New feature: #!ifexp - conditional preprocessor blocks
by Daniel-Constantin Mierla 15 Sep '22

15 Sep '22

Hello, a new feature has landed to Kamailio devel version, bringing in more flexibility for preprocessing of the kamailio.cfg file. It is about #!ifexp, which allows to evaluate an expression created with defined IDs, string and number values. Based on evaluation result, being true or false, parts of the config file can be enabled or disabled. An extensive number of operators can be used in expressions, such as: +, -, *, /, ==, !=, <, >, <=, >=, ||, &&, etc. The evaluation is done using snexpr (https://github.com/miconda/snexpr), which was embedded inside Kamailio code. Here are some simple kamailio.cfg examples: #!ifexp KAMAILIO_VERSION >= 5006000 loadmodule "tlsa.so" #!else loadmodule "tls.so" #!endif #!ifexp MOD_xlog && (OS_NAME == "darwin") xlog("running on MacOS\n"); #!endif Documentation and more examples can be found on the wiki portal at: - https://www.kamailio.org/wikidocs/cookbooks/devel/core/#ifexp Testing would be appreciated, feedback can be addressed to sr-users mailing list!

evapi_async_relay() and workers
by Alex Balashov 14 Sep '22

14 Sep '22

Hi, When a transaction suspended by evapi_async_relay() is resumed, in which child processes is it resumed? Is it in the dedicated “EVAPI RELAY” workers defined by the ‘workers’ modparam to ‘evapi’? If this is so, just trying to work out the concurrency implications and the optimal size for the worker pool for maximal throughput. It sounds, at first glance, like it should be roughly similar to the sizing considerations for listener children. Thoughts welcome!

Kamailio + RTPEngine SIP Proxy...
by Jerry Kendall 12 Sep '22

12 Sep '22

Hi There, It's been a few years since I joind the group and I have watched and learnt and played but, I am stuck... I have searched hi & low but I can't seem to find what I am looking for. Is is do-able to have SIP Phones proxy through Kamailio/RTPengine and have the connection relayed to a freeswitch system where all the work is done. I need to have Kamailio act as proxy ONLY - no need to do AUTH, and I need Kamilio to have the RTPEngine have the media but only as proxy. I have FreeSWITCH doing all the IVR/VM/CONF/etc.... So: 1) The SIP Phone sends everything to the Kamailio system, the Kamailio system will relay everything to the FreeSWITCH system (requests and replies) 2) The FreeSWITCH system will send everything to the Kamailio system which will relay everything back to the SIP Phone (requests and replies) 3) The SIP phones are behind NAT 4) The Kamailio and FreeSWITCH systems are on the public internet with public IP addresses I have found a few sample kamailio.cfg files but, I can get REG to make it through but no SUBCRIBE wont get NOTIFYs back, etc... I seem to get parts but not all the way. If this is doable, and I assume it is, is there a config file someone can share with me? or point me to? Jerry

Siremis JSONRPC problem on Bullseye
by Joseph Goettgens 12 Sep '22

12 Sep '22

I am not sure what I have to look for and I didn't change the initial config files (except for the 666 mode for kamailio_rpc.sock). As far as Kamailio is concerned the socket files files do exist: root@deb11srv1-kamailio:/var/www/siremis-5.3.x# ls -l /run/kamailio/ insgesamt 4 srw------- 1 kamailio kamailio 0 7. Jun 11:37 kamailio_ctl -rw-r--r-- 1 kamailio kamailio 5 7. Jun 11:37 kamailio.pid prw-rw---- 1 kamailio kamailio 0 7. Jun 11:37 kamailio_rpc.fifo srw-rw-rw- 1 kamailio kamailio 0 7. Jun 11:37 kamailio_rpc.sock When I look at siremis/log/ERR.log I repeatedly get: '06/07/2022','09:43:29','ERR','ErrorHandler','socket_bind(): unable to bind address [2]: No such file or directory','' This disappears when I put the local file socket in /tmp: <UnixSockLocal name="unixsocklocal" address="/tmp/siremis_rpc.sock" timeout="3.0"/> which was probably done this way in previous versions of Siremis (before systemd private tmp config). In this case I get no error messages, but still no answers (as expected). The next step seems to get UnixSockLocal right.

MANAGE_REPLY: do_action(): bad uri: How to mirror username changes from the invite to all replies?
by Benoît Panizzon 09 Sep '22

09 Sep '22

Hey there! Kamailio is being used between CPE (customer) and IC. Towards IC we use e164 numbers Towards customers we use 'localized' numbers and also ensure that Privacy is enforced by setting usernames to 'Anonymous' if Privacy is set to id, remove unwanted header etc. I realized, that I have to apply the same translations to replies and re-invites to make sure, they do not leak unwanted information towards the customer. But when I try to set: onreply_route[MANAGE_REPLY] $fU,$rU,$tU within MANAGE_REPLY I get: do_action(): bad uri Just removing unwanted header works fine it looks as it's only changing the usernames that causes this issue. What would be the proper was to change usernames in replies? Is there any module which would apply the same user translations as done with the invite to all replies and re-invites? -- Mit freundlichen Grüssen -Benoît Panizzon- @ HomeOffice und normal erreichbar -- I m p r o W a r e A G - Leiter Commerce Kunden ______________________________________________________ Zurlindenstrasse 29 Tel +41 61 826 93 00 CH-4133 Pratteln Fax +41 61 826 93 01 Schweiz Web http://www.imp.ch ______________________________________________________

tls_wolfssl talk at KWO: traffic generation scripts are online
by Richard Chan 09 Sep '22

09 Sep '22

Hi sr-users, The TLS traffic generation scripts are online here: * SIP library - fork of sippy/b2bua - use main-async branch https://github.com/space88man/b2bua This branch is an async refactoring of sippy; the master branch of the repo is the regular sync+elperiodic version. * runtime UA generation scripts: https://github.com/space88man/multiuac-tester This repo contains the TLS-client transport (sippy out-of-the-box supports UDP); also gratuitously uses the match/case syntax for fun (so needs Python 3.10) * no documentation: the scripts/t_register.py and scripts/t_phone.py should give you an idea how to create UACs. The script in the talk is scripts/t_register.py - creates SIP UACs that sit in an infinite loop and do REGISTER and keepalive ('\r\n\r\n'). Disclaimer: this is not a SIP-scenario framework like SIPp; SIP messages are programmatically created using sippy; e.g., the test scenario does not need to handle RTP media so the SDP body is a hardcoded string. Regards S-P

Dynamic rtimer interval, transaction to replace in-memory dispatcher list
by Anton Yabchinskiy 05 Sep '22

05 Sep '22

Hello, I have two slightly related questions, and would appreciate any advice on the matter. The first one is about dynamic `rtimer` (or `timer`) intervals. In the route, called by the timer process there is a request to a neighbor service. In the response there's a set of new destinations for in-memory dispatcher list and some TTL value. And I need to adjust the timer interval based on this TTL (e.g., timer interval may be 10 min, but TTL may suggest to request destinations every 5 min since now). Also, the first call to the timer route should be at T+0, not at T+interval. As far as I can tell from `rtimer` module implementation, that's unfeasible. But maybe I'm missing something? Any suggestion on how one should implement something like this? The second one is about updating in-memory dispatcher list. After receiving and parsing new destinations in the timer route, the previous in-memory destinations must be replaced by these new destinations. The naive way of doing so would look something like: `dispatcher.reload` to clear previous list, then a series of `dispatcher.add` calls to add new destinations. But a failed `add` call may lead to wrong in-memory destinations set. As far as I understand I should start using some transaction-aware database for dispatcher destinations, and literally write a transaction. Are there any other ways to solve this?

Hi Community, I have set up a SBC with Kamailio. I am testing voice call from external network to my network and voice call from my network to external network. When I send SIP messages to external network, I want to hide Via and Record-Route headers but when I receive replies from the external network I want to restore these Via and Record-Route headers to my network. How to store and restore these headers in Kamailio configuration ? Could you help on this? Thanks Anthony Blandin

Dispatcher module and xavp_dst
by Pyry Aaltonen 01 Sep '22

01 Sep '22

Hello, I’m quite new user with kamailio (heard first time about it a year ago and joined the list yesterday) and now wondering how the xavp_dst should work. I had read from the documentation that ”The first XAVP is the current selected destination.” I use ds_select_dst with alg 13. And my kamailio version is kamailio 5.5.3 (x86_64/linux) So when my dispatcher list is like (I have also tried to differ the priority value like 10 and 1, but doesn’t make difference) 10 sip:1.2.3.4;transport=tcp 10 1 type=type1 10 sip:4.3.2.1;transport=tcp 10 1 type=type2 If one of the destinations fails (dx/ip), and it happens to be the one with higher priority or the one that just gets higher position in the dispatcher list if the prio Is equal. My xavp_$xavp(dsdst=>attrs) get null value. And, if I try to seek $(xavp(dsdst[0]=>attrs) or $(xavp(dsdst[1]=>attrs) I also got nothing. If both destinations are up with equal priority, it selects them with round-robin, and the xavp_$xavp(dsdst=>attrs) has the type value of the selected destination as expected, also the $(xavp(dsdst[0]=>attrs) or $(xavp(dsdst[1]=>attrs) contains the destinations so that the selected is 0 and the other is at position 1. The $du is updated as I expect so if one fails the other one is selected always, why the xavp_dst isn’t working same way, or am I missing something? If needed I’ll try to provide more information, Thanks already in advance -Pyry

Disabling video rtp proxing
by mayamatakeshi 31 Aug '22

31 Aug '22

Hi, I'm using rtpengine for RTP proxying with kamailio. I use it just for audio. But eventually some terminal reinvites offering video. I don't want to refuse the request but just disable RTP proxying for video as my employer has limited bandwidth and want to reserve it only for audio. So I checked the rtpengine module documentation but it seems there is no way to restrict RTP proxying to be performed only for m=audio. I tried some things like replace_body("^m=video [0-9]+", "m=video 0"); and subst_body('/^m=video [0-9]+ /m=video 0 /'); and msg_apply_changes(); but still the RTP proxying for video is set up. Any hints on how to solve this?

Intermittent delays relaying BYE (up to 1s)
by Lewis Hutchinson 31 Aug '22

31 Aug '22

Ok so making progress but still a little confused, hopefully this forum can shed some light on this behaviour. Using the hints provided (thanks all so far) and the latency logging from the cookbook I have managed to isolate the issue down to RTPengine introducing the delay. INFO: app_python3 [apy_kemi.c:1820]: sr_apy_kemi_exec_func(): alert - action KSR.rtpengine.rtpengine_manage(...) took too long [1003089 ms] (file:(null) func:(null) line:252) What is confusing is, I don't believe this block should be being called. when the BYE is triggered, it routes to ksr_route_withindlg # handle requests within SIP dialogs if self.ksr_route_withindlg(msg)==-255 : return 1 from within the ksr_route_withindlg a check is done to see if any RTPengine work needs doing # Handle requests within SIP dialogs def ksr_route_withindlg(self, msg): if KSR.siputils.has_totag()<0 : return 1 # RTPEngine handling for UPDATES & reINVITES with sdp if self.ksr_route_rtpengine(msg) == -255: return 1 RTPengine is configured in a way to step in whenever there is an SDP present based on Content-Type: application/sdp # RTPengine handle anything with SDP def ksr_route_rtpengine(self, msg): if KSR.textops.has_body_type("application/sdp"): KSR.rtpengine.rtpengine_manage( "RTP/AVP replace-session-connection replace-origin ICE=remove") return 1 What I can understand is why is this being called and erroring introducing the delay when there is no Content-Type: application/sdp in a BYE ??? As a quick fix I have put this in which stops the problem (I am sure there is better ways to handle this but for now this works in a DEV environment) def ksr_route_rtpengine(self, msg): if KSR.is_BYE(): return 1 if KSR.textops.has_body_type("application/sdp"): KSR.rtpengine.rtpengine_manage( "RTP/AVP replace-session-connection replace-origin ICE=remove") return 1 Can anyone see why this would occur? Why is sr_apy_kemi_exec_func(): alert - action KSR.rtpengine.rtpengine_manage(...) even being called for this BYE ? when there is no Content-Type: application/sdp Lewis

Intermittent delays relaying BYE (up to 1s)
by Lewis Hutchinson 26 Aug '22

26 Aug '22

Thanks Alex and Kaufman, As you said there is an element of db blocking for accounting, but I don't see the same impact when the INVITE goes through and sets the accounting flags. I will look to disable accounting and see if it improves things. If not, I will have a look at benchmark to try and pin it down. It is not causing any noticeable delay in the clearing down of the call to the end users but I want to try and optimise the cleardown if possible. Once I have tested this I will report back. Thanks for your assistance. Lewis

Is there any buffer that I have to increase to get the complete output? command used: ``` echo '{"jsonrpc": "2.0", "method": "dispatcher.list", "reply_name": "kamailio_reply_fifo", "id": 1}' | nc -u 192.168.1.1 8090 ``` kamailio related config: modparam("jsonrpcs", "fifo_name", "/tmp/kamailio_request.fifo") modparam("jsonrpcs", "transport", 6) modparam("jsonrpcs", "fifo_mode", 0600) modparam("jsonrpcs", "fifo_user", "kamailio") modparam("jsonrpcs", "dgram_socket", "udp:MY_INTERNAL_IP_ADDR:8090") modparam("jsonrpcs", "dgram_timeout", 2000) modparam("jsonrpcs", "pretty_format", 1) output: [image: image.png] Thanks

Kamailio 5.3 call forwarding
by Derek OSS 24 Aug '22

24 Aug '22

Hi, I'm using Kamailio 5.3 and I am interested in doing call forwarding. I am interested in having a user "alice" bypass the SIP REGISTER step and have their SIP INVITE request/call forwarded to another SIP user "bob" (who, let's just say for now is within the same domain, so accessible by the same SCSCF and if it makes things simpler, let's say that bob went through the register step). In the PCSCF configuration, I've tried doing something like this: route { route(TEST) ... } route[TEST] { $ru = "sip:bob@domain.com" if (!t_relay("scscf.domain.com",6060)) { sl_reply_error(); } exit; } Instead of $ru, I've also tried using uac_replace_to, providing both the To and URI fields with Bob's SIP URI. When I try using the $ru, the S-CSCF still seems to use Alice's R-URI instead of Bob's. When I try using uac_replace_to, I get a 403 error saying that I need to register with the S-CSCF first. Am I going about this the correct way? Thank you. Derek

remove header from reply?
by Brett Nemeroff 19 Aug '22

19 Aug '22

Hello, I'm receiving calls which I forward to a server I KNOW will reply with a 302. When I get that 302, I parse some information and then t_reply(302) the originator. The 302 I create needs to have it's own contact header which I am adding with append_to_reply(). That works great. BUT the contact header from the original 302 is hanging around. Now I have two contact headers :( How can I get rid of the original 302's contact header? remove_hf() doesn't work in this context since it's a reply. So I need a kind of "remove_header_from_reply()". Thanks, Brett

Processing Async HTTP Requests in Real-time
by Brett Nemeroff 19 Aug '22

19 Aug '22

Hello Kamailio Team! I've tried following the documentation for http_async_query() with suspend=1 and not getting results I'm expecting. Perhaps I'm misunderstanding the documentation. Basically I'm performing a http_async_query() with suspend set to 1 and a "route_name" set to HTTP_REPLY. When my query executes, it appears that Kamailio stops processing in that route block, suspends, and then when a reply is available, it continues in HTTP_REPLY. That makes sense. I pull the return value and set some $var and $avp. When I get to the end of the HTTP_REPLY block, I'm EXPECTING it to RESUME FROM the suspended location from the original route block, which it does NOT seem to do. Is that expected? For what it's worth, I did test just continuing my route logic in HTTP_REPLY and just forgetting about the original route block (moved all the remaining processing logic into HTTP_REPLY) However, existing $avp and $vars that were already set within the transaction were not set. So that's not possible either. I'm pretty sure there is a right way to do this without getting hacky. Can someone help me out? And yes, I know what I'm trying to do sounds like sync, but I want async to handle high volume and the potential for my external URL to lightly block. I believe the right way to do this is with async+suspending. Thank you, Brett

packets exceeding MTU size
by Ali Taher 18 Aug '22

18 Aug '22

Hello all, Lately I faced an issue that Kamailio is not responding to some invite packets coming from SBC. When investigating I found that these packets exceeds MTU size. Could this be the issue? Knowing that in Kamailio configuration I have a condition on is_method("INVITE"). Could be that in case of packet exceeding MTU size it's not considered as invite packet by Kamailio? I have Kamailio 5.2.5. Regards, Ali Taher

Kamailio not responding in heavy load
by Ali Taher 17 Aug '22

17 Aug '22

Hello all, I'm using sqlops module to connect to postgres and get the routing of calls from postgresql database. In order to troubleshoot issues in case they happened, I added each call details to Kamailio log. In some cases, when there is heavy traffic load (around 100 cps), I don't find some calls in Kamailio log, knowing that I can find them on the switch log (switch sending the invite packets to Kamailio). When checking the traces on these calls taken by the switch, it's clear that Kamailio is not responding to the invite packets sent by the switch. It could be because there are no available process to handle the call at this moment (I have set fork=14) Is it possible to check if there are calls pending in the queue? Regards,

Remove and Re add FROM in 200 OK sl reply
by Lewis Hutchinson 16 Aug '22

16 Aug '22

Hello All kamailio 5.5.3 KEMI Python Lab environemnt Is there a reason why this does not work? Lines 2 and 3 work but the removal of the initial From is not working on Line 1 1. KSR.hdr.remove("From") 2. KSR.hdr.append_to_reply("From: " +KSR.pv.gete("$fn") + " <"+KSR.pv.gete("$fu") + ">" + ";tag=" +KSR.pv.gete("$ft") + "--1234" + "\r\n") 3. KSR.sl.sl_send_reply(200, "OK") In a SUBSCRIBE/NOTIFY scenario I am trying to control the From Tag returned in the 200OK so I can use the same one in subsequent NOTIFY messages generated outside of Kamailio, my theory is use the From tag in the Subscribe and append it on the reply with -1234 for example (this is only in a Lab at this stage, any other options please let me know) Whenever I do this I end up with 2 From headers (see below) SIP/2.0 200 OK Via: SIP/2.0/UDP 192.168.1.67:5060;branch=z9hG4bK-f710a11a;rport=46404;received=xx.yy.xx.yy From: " testuser" sip:limeant30@sip.viazeta.com;tag=bf8745def06c7b12 To: <sip: testuser(a)sip.viazeta.com>;tag=47969b75f14e6954812863912d1cf21c.b5f3318f Call-ID: b21ba770-9b5836aa(a)192.168.1.67 CSeq: 18137 SUBSCRIBE Contact: "testuser" <sip:testuser@ xx.yy.xx.yy:46404> Expires: 3600 From: "testuser" sip:testuser@testbed.com;tag=bf8745def06c7b12--1234 Content-Length: 0 I have tried many many variations but the original From header always persists I have checked the debug logs and it says it has been removed Anyone know what I am missing?

I've been attempting to get Kamailio configured and working for some considerable time now (read: Years of occasional tinkering, and weeks of recent dedicated evening work) -- all without success. I have a sip trunk from sipgate, with two PSTN numbers assigned. My local network has a static external IP, with an internal private network. Currently I have Kamailio running within the intenal network along with two physical sip telephones (gigaset and an old grandstream), although I do have the option to put kamailio within a DMZ if necessary. Would anyone have a working config file that they could share please, permitting incoming and outgoing calls? With grateful thanks, Phil

Kamailio has unconfined processes
by HimaBindu G 11 Aug '22

11 Aug '22

Hi, Problem Description: Customer security scan returned unconfined services on Kamailio. Unconfined processes run in unconfined domains Rationale: For unconfined processes, SELinux policy rules are applied, but policy rules exist that allow processes running in unconfined domains almost all access. Processes running in unconfined domains fall back to using DAC rules exclusively. If an unconfined process is compromised, SELinux does not prevent an attacker from gaining access to system resources and data, but of course, DAC rules are still used. SELinux is a security enhancement on top of DAC rules - it does not replace them Solution Investigate any unconfined processes found during the audit action. They may need to have an existing security context assigned to them or a policy built for them. Notes: Occasionally certain daemons such as backup or centralized management software may require running unconfined. Any such software should be carefully analyzed and documented before such an exception is made. See Also https://workbench.cisecurity.org/files/2485 For Kamailio ====== The command returned : 00 kamailio 00 kamailio 00 kamailio 00 kamailio 00 kamailio 10 kamailio 10 kamailio 10 kamailio 10 kamailio 00 kamailio 00 kamailio 00 kamailio 00 kamailio 33 kamailio 33 kamailio 33 kamailio 32 kamailio 17 kamailio 16 kamailio 33 kamailio 00 kamailio 00 kamailio 03 kamailio 05 kamailio 18 kamailio 17 kamailio 18 kamailio 18 kamailio 07 kamailio 00 sleep is any security context available to assign kamailio processes ? theses services can be run as confined services ? Please suggest us with resolution, thanks in advance. Thanks & Regards, Hima Bindu.

Kamailio World Conference - Sep 7-8, 2022 - Online
by Daniel-Constantin Mierla 10 Aug '22

10 Aug '22

For the 3rd year, we are planning an online version of Kamailio World Conference! At the beginning of 2022, the situation was not clear in terms of whether pandemic would decrease enough in intensity and we would be allowed to organize an on-site event late spring/beginner of summer, when the usual Kamailio Conference took place in Berlin, therefore we chose the safety path. But we hope that next year we will return in-person to the beautiful Berlin city center! The event this year, to happen in 4 weeks from now (Sep 7-8, 2022), follows the structure from previous edition, being two afternoons with presentations about Kamailio, sharing technical solutions and open discussions, allowing the community to interact and reconnect. The website of the event: - https://kamailioworld.com/k10-online/ There is no registration required, the event will happen on live video conferencing, also streamed to youtube. A text chatting channel will be made available as well. If you want to present, just send me the title and a short description -- we encourage community members to step forward and share their knowledge. It has to be related to Kamailio and fit within a 30min slot (including the questions). The agenda will be released in the near future. The event will be used also to celebrate 21 years of Kamailio project development, first commit being done on Sep 3, 2001. Two other major celebrations for 2022 to make the party bigger: - 20 years of open source for the project -- after one year of internal development, GPL was added on Sep 19, 2002 and source code was released to public - the 10th edition of Kamailio World Conference Book the dates in your agenda! I am looking forward to a very interesting event and (re-)connecting with many of you! Daniel -- Daniel-Constantin Mierla -- www.asipto.com www.twitter.com/miconda -- www.linkedin.com/in/miconda

Syncing Registration Database across Kamailio Pairs
by harneet singh 09 Aug '22

09 Aug '22

Hi Experts, We have been using Kamailio in an Active/Standby Pair(with Keepalived under the rugs moving the single Virtual IP to access the Active Kamailio) for sometime now. *Kamailio also acts as a Registrar for our webrtc endpoints. * It has been serving the purpose pretty well and now we have a requirement where we need to be syncing the Registration DB between Two Pairs of Kamailios. Kamailio-Active(*Pair 1*) -------- Kamailio-Standby(*Pair 1*) || Kamailio-Active(*Pair 2*) -------- Kamailio-Standby(*Pair 2*) We generally keep the counterpart in the same Pair as a notifier( *modparam("dmq", "notification_address", "sip:PEER1_IP:5060")* ) so as to sync the dialogs and the userloc data too( *modparam("dmq_usrloc", "enable", 1) * ). In order to achieve the said requirement with the other Pair, we added another "*notification_address*" in the kamailio cfg. At this point, we ran into weird issues. *1. *With Kamailio ver *5.3.2, *the subsequent *notification_address *line in the cfg file, seemed to be overriding the previous one. Hence we see only the latter peer in the dmq list nodes. Example: modparam("dmq", "notification_address", "sip:*172.27.45.77* :5090") modparam("dmq", "notification_address", "sip:*172.27.45.200* :5090") In this case, the "*kamcmd dmq.list_nodes*" would show the local Machine and 172.27.45.200 as the only nodes in the output, ie *172.27.45.77 is not showing up at all,* which is problematic, since the local machine(172.27.45.243 in our case) would not been able to send any dmq sync info to its peer(172.27.45.77) in the same Pair. To see if the above issue might have been addressed in later release, we upgraded to the latest Kamailio ver *5.6.0* *To our respite, the above issue no longer exists in the new version*(though not sure which immediate release after v 5.3.2 it would have been initially fixed.) This is where we have a new issue explained below: *2. *The registration data does get synced to the peer Kamailio in the same Pair, and also to the Kamailio instances in the other Pair. However, the *Socket* Parameter in "*kamctl ul show*" output shows *[not set] *even on the side where the websocket connection actually exists. [root@localhost ~]# *kamctl ul show * { "jsonrpc": "2.0", "result": { "Domains": [{ "Domain": { "Domain": "location", "Size": 1024, "AoRs": [{ "Info": { "AoR": "9008077221", "HashID": 1952082106, "Contacts": [{ "Contact": { "Address": "sip:Harneet_qifir@172.24.58.210", "Expires": 159, "Q": -1, "Call-ID": "vfli2uv8du3ppda73q5ppe", "CSeq": 106, "User-Agent": "EngageDigital", "Received": "sip:172.27.44.252:60070;transport=ws", "Path": "[not set]", "State": "CS_NEW", "Flags": 0, "CFlags": 0, * "Socket": "[not set]", <<<<<<<<<<<<<<<<<<<<<<* "Methods": 7071, "Ruid": "uloc-62f26e3b-2677-1", "Instance": "<urn:uuid:4fbd3e96-b4de-497b-886d-1ca8ffa016a4>", "Reg-Id": 1, "Server-Id": 0, "Tcpconn-Id": -1, "Keepalive": 0, "Last-Keepalive": 1660063892, "KA-Roundtrip": 0, "Last-Modified": 1660063892 } }] } } ], In order to confirm that the socket actually exists on this Kamailio instance, I am pasting the below outputs from the same machine, where ws dump and even the native netstat confirms that. [root@localhost ~]# *netstat -tunelap | grep 60070* tcp 0 0 172.27.45.199:8080 172.27.44.252:*60070* *ESTABLISHED* 994 17322355 16230/kamailio [root@localhost ~]# *kamcmd ws.dump* { connections: { 1: ws:172.27.44.252:*60070* -> ws:172.27.45.199:8080 (state: *OPEN*, last used 24s ago, sub-protocol: sip) } info: { wscounter: 1 truncated: no } } We do need to distinguish the actual Kamailio instance where the websocket connection actually exists, so as to route the call ahead from the same instance, or if it does not exist(and it's merely a sync'ed registration data received over DMQ Channel), then the Kamailio should route the call ahead to the Kamailio instance in the other Pair, which can then route it ahead to the Registered webrtc endpoint. We were hoping to use the Socket Parameter output, but for the said problem, unable to use the same as an indicator. *So what would be the best way to identify which Kamailio has the websocket connection with the Actual endpoint*? Should we rely on the output of netstat or ws.dump to infer that? I mean this needs to be done in kamailio.cfg for each call, so want to know the best way, or if there is completely different approach that can be suggested? Apologies for the long email, but any pointers will be much helpful.

recompute distribution list
by David Villasmil 08 Aug '22

08 Aug '22

Hello guys, Is it possible to have dispatcher recompute the distribution list? i.e. one server goes down, all traffic for that server goes to the next one, doubling traffic on that one. Is there a way of, when a host becomes unreachable, recompute the whole list? Regards, David Villasmil email: david.villasmil.work(a)gmail.com phone: +34669448337

Contact header modification - Kamailio
by Ankit Jayswal 04 Aug '22

04 Aug '22

Hello Team, I am in need to modify the contact header in Kamailio before sending an INVITE request to the SIP trunk provider. Basically the IP address I need to modify in the contact header. Please suggest a better way to do this. Below is an example. *OLD (Existing):* Contact: <sip:009169240xxx@*45.118.162.x:5080*;alias=10.52.26.102~5080~1> *NEW (Needed):* Contact: <sip:00912269240xxx@*10.52.26.98:5060 <http://10.52.26.98:5060>*> I tried various functions from the textops module but no hope. I am looking for a function that can replace the contact header's value. Please help me with this. -- Thanks & Regards, *Ankit Jayswal* | Specialist - Software Development

Support of ECDHE cipher suites for tls connection in kamailio
by Илья Болмосов 03 Aug '22

03 Aug '22

Hello. I have a question about support of ECDHE cipher suites in kamailio-5.6.0 in centos7 with installed OpenSSL 1.0.2k-fips. We received kamailio with its modules from https://rpm.kamailio.org/. Our client can use only cipher suites: TLS_AES_256_GCM_SHA384 (0x1302) TLS_CHACHA20_POLY1305_SHA256 (0x1303) TLS_AES_128_GCM_SHA256 (0x1301) TLS_ECDHE_ECDSA_WITH_AES_256_CBC_SHA (0xc00a) TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA (0xc014) TLS_ECDHE_ECDSA_WITH_AES_128_CBC_SHA (0xc009) TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA (0xc013) TLS_EMPTY_RENEGOTIATION_INFO_SCSV (0x00ff) And some of them are supported by our openssl: $ openssl cipher -V ... 0xC0,0x14 - ECDHE-RSA-AES256-SHA SSLv3 Kx=ECDH Au=RSA Enc=AES(256) Mac=SHA1 0xC0,0x0A - ECDHE-ECDSA-AES256-SHA SSLv3 Kx=ECDH Au=ECDSA Enc=AES(256) Mac=SHA1 ... 0xC0,0x13 - ECDHE-RSA-AES128-SHA SSLv3 Kx=ECDH Au=RSA Enc=AES(128) Mac=SHA1 0xC0,0x09 - ECDHE-ECDSA-AES128-SHA SSLv3 Kx=ECDH Au=ECDSA Enc=AES(128) Mac=SHA1 ... But when trying to connect with, for example, cipher suite ECDHE-RSA-AES256-SHA (the same with other 3 cipher suites), we receive, that it is not allowed: $ openssl s_client -connect ${kamailio-serper-ip}:${kamailio-server-port} -cipher ECDHE-RSA-AES256-SHA ... SSL handshake has read 7 bytes and written 121 bytes --- New, (NONE), Cipher is (NONE) Secure Renegotiation IS NOT supported Compression: NONE Expansion: NONE No ALPN negotiated SSL-Session: Protocol : TLSv1.2 Cipher : 0000 ... To exclude the influence of other factors, I installed nginx on the same machine with usage of the same tls certificate and it can use cipher suites ECDHE-RSA-AES256-SHA and ECDHE-RSA-AES128-SHA. $ openssl s_client -connect ${nginx-serper-ip}:${nginx-server-port} -cipher ECDHE-RSA-AES256-SHA ... SSL handshake has read 3271 bytes and written 406 bytes Verification: OK --- New, TLSv1.0, Cipher is ECDHE-RSA-AES256-SHA Server public key is 2048 bit Secure Renegotiation IS supported Compression: NONE Expansion: NONE No ALPN negotiated SSL-Session: Protocol : TLSv1.2 Cipher : ECDHE-RSA-AES256-SHA ... So, the reason of failed handshake is, probably, kamailio. Tried to add cipher_list modparam: modparam("tls", "cipher_list", "ECDHE-RSA-AES256-SHA") but result is the same: $ openssl s_client -connect ${kamailio-serper-ip}:${kamailio-server-port} -cipher ECDHE-RSA-AES256-SHA ... SSL handshake has read 7 bytes and written 121 bytes --- New, (NONE), Cipher is (NONE) Secure Renegotiation IS NOT supported Compression: NONE Expansion: NONE No ALPN negotiated SSL-Session: Protocol : TLSv1.2 Cipher : 0000 ... Can you, please, help me to add support of cipher suites ECDHE-RSA-AES256-SHA and ECDHE-RSA-AES128-SHA to kamailio?

Limit cps per destination gw
by Jon Bonilla (Manwe) 02 Aug '22

02 Aug '22

Hi I'm thinking on having a cps preference for each pstn gw that I can check. I've started thinking in the pike module but it won't allow me to set custom cps per peer. seems that the threshold is global. Ratelimit module needs the queues to be set as modparam, not dynamic AFAICS. Any hints? cheers, Jon -- PekePBX, the multitenant PBX solution https://pekepbx.com

Sharing Database between three kamailios
by Waqar 40 01 Aug '22

01 Aug '22

I have three Kamailios in three different servers which are dispatching calls to 9 asterisks in three different servers using load balancing. All these Kamailios are using databases installed on that servers. As the entries of the dispatcher table are the same for all the Kamailio, so I want that these Kamailio use a single database installed on one of the servers. All these Kamailios instances should use the same database which is common between them. And also I want these Kamailios to write into the database by creating a table that stores all the active calls in three Kamailios. Is it possible? How can I do it? Please guide me with somewhat explanation as I am not this much expert in Kamailio. Waiting for a quick response. Regards VoIP Engineer Vicky

Kamailio behind NAT
by Алексей Якимкин 29 Jul '22

29 Jul '22

Hello, I have kamailio in local network behind NAT. Kamailio have one interface eth1 with ip 10.130.0.23 UserAgent - (internet) - (178.0.0.169)router_with_NAT - (LAN) - kamailio+rtpproxy - pbx I made two listeners: listen=udp:10.130.0.23:5070 #to pbx in lan (I don`t want to put via header with 178.0.0.169) listen=udp:10.130.0.23:5060 advertise 178.0.0.169:5060 #to internet (UserAgent need to get via header with 178.0.0.169 ) mhomed = 1 # I think It not useful for my case UserAgent send Register and Invite to 178.0.0.169:5060, Kamailio get it on udp:10.130.0.23:5060 Kamailio Relay it to udp:10.130.0.23:5070 My pbx get requests from udp:10.130.0.23:5070 with via header 10.130.0.23 Responses to UserAgent go from udp:10.130.0.23:5060 with via 178.0.0.169 In RELAY block: if ($Ru == «udp:10.130.0.23:5070») { #set_send_socket(«udp:10.130.0.23:5060»); $fs = «udp:10.130.0.23:5060»; #force_send_socket(«udp:10.130.0.23:5060»); } else { #set_send_socket(«udp:10.130.0.23:5070»); $fs = «udp:10.130.0.23:5070»; } #$fs = «udp:10.130.0.23:5070»; if (!t_relay()) { sl_reply_error(); } route[REGISTRAR] { if ($rd == "mydomain.ru" || $rd == "mydomain2.ru") { set_send_socket("udp:10.130.0.23:5070"); } } It works for requests from UserAgent to PBX. But INVITE from my pbx to UserAgent goes only through udp:10.130.0.23:5070 , Kamailio realy it to internet from udp:10.130.0.23:5070 I get error in syslog: (pv [pv_branch.c:62]: pv_get_branchx_helper(): error accessing branch [0]) I tried set_send_socket(«udp:10.130.0.23:5070»); and $fs = «udp:10.130.0.23:5070»; Why I can`t relay outgoing requests to internet through another socket? -- Best regards, Alex

[REGISTRAR] Registered. How to match $sut to usrloc received ?
by Richard Edmands 29 Jul '22

29 Jul '22

Hey Kamailio Users, So the scenario is we get the registers. Load them, slightly oddly as we also fill in the received section, not something I usually do. Then when they send an invite, the To and From headers are real phone numbers and for some reason the contact header isn't their username. So to compensate for that I'm trying to match their connection ($sut) using registered, but after a couple of hours I haven't been able to get it to match up. Not sure what I'm missing. ul.dump gets me Received: sip:sipclientpublicip:2353;transport=udp so we know that part is loading $sut correctly into the user location data. modparam("usrloc", "matching_mode", 2) modparam("registrar", "xavp_rcd", "ulrcd") modparam("registrar", "received_avp", "$avp(i:42)") $xavp(regcfg=>match_received) = $sut; if (registered("location","$sut", 2, 1)) { After that block of code $sut is sip: sipclientpublicip:2353;transport=udp which is what's in usrloc for received, but it's not match. There's probably a much smarter way of doing this that I've completely missed, if so then that'd be excellent. But if I'm on the right path somewhat then it would be great to get this working.

Hi, You are currently using TLSv1/SSLv3 ECDHE-RSA-AES256-GCM-SHA384 256 Teams stopped TLSv1/ TLSv1.1 and only allowing TLS1.2+ So change your TLS settings to enforce it only method = TLSv1.2+ after restarting kamailio your teams connections should be good.

uac replace PRACK trouble
by Алексей Якимкин 22 Jul '22

22 Jul '22

Hello, pbx -> kamailio -> provider kamailio registers (uacreg) on provider. When I call through my provider I need to change headers To From and PAI. I tried with uac_replace_from and uac_replace_to. $tU for example 0987656789 if($fU=~"1234567") { uac_replace_from("sip:provider_login@provider.com"); uac_replace_to("sip:$tU@provider.com"); } My provider answers on Invite with 183 progress, so pbx answers with PRACK. Kamailio change To and from like this: To: <sip:0987656789@provider.comsip:0987656789@provider.com>;tag=..... To: <sip:0987656789@provider.comsip:0987656789@provider.com> From: <sip:provider_login@provider.comsip:provider_login@provider.com >;tag=..... From: <sip:provider_login@provider.comsip:provider_login@provider.com> Is it a bug? I tried to disable this modification for PRACK u REQINIT ($csb != "2 PRACK") It haven't worked for me. I solved this issue with this code. remove_hf("From"); if ($ft == $null) { insert_hf("From: <sip:provider_login@provider.com>\r\n", "To"); } else { insert_hf("From: <sip:provider_login@provider.com>;tag=$ft\r\n", "To"); } version: kamailio 5.7.0-dev0 (x86_64/linux) Ubuntu 18 -- Regards, Alex

incomplete values and Wrong Counting for $hfl and $hflc
by Patrick Karton 21 Jul '22

21 Jul '22

the counting and values provided by $hfl and $hflc are wrong and incomplete from my understanding. looking at the source code these pseudo vars count the body values of Via, Record-Route and Route headers. in kamalio 5.6.1 with Record-Route: <sip:1.1.1.1;lr=on;nat=yes> Record-Route: <sip:2.2.2.2:5060;lr;transport=udp>,<sip:3.3.3.3:22506;lr;transport=udp> i get $hflc(Record-Route) == 2 instead of 3 and $(hfl(Record-Route)[0]) == 1.1.1.1 $(hfl(Record-Route)[1]) == 2.2.2.2 $(hfl(Record-Route)[3]) does not exists.

Using Kamailio with Teams
by Javier González Muñoz 21 Jul '22

21 Jul '22

Hi, I'm using kamailio with Teams like SBC and asterisk. Works perfectly less one thing. When I make a call asterisk to Teams, in my Teams app I see 3 popup notifications, and 3 calls in my history. If I call Teams to Asterisk, perfect.. When I make an asterisk to Teams call, I get the trace from Asterisk and I can see three 180, I don't know if this is the problem, but are there any way to fix it? Limit to 1 notification? Thanks

iterate trough all Record-Route values via @hf_value.Record_Route
by Patrick Karton 21 Jul '22

21 Jul '22

Hello All, i would to iterate through all ips in Record-Route through @hf_value.Record_Route. if i put static index like @hf_value.Record_Route[0] it works. but $var(i) = 0; @hf_value.Record_Route[$var(i)] does not work. is there a way to get the count of all headers values through @hf_value.Record_Route For example i would like to iterate through all Record-Route Values if i receive it like this Record-Route: <sip:1.1.1.1;lr=on;nat=yes> Record-Route: <sip:2.2.2.2:5060;lr>,<sip:3.3.3.3:22506;lr>

Using usrloc db_insert_update in a dmq replicated environment with shared db ?
by Matteo Brancaleoni 19 Jul '22

19 Jul '22

Hi, I was wondering if it is safe from a cache consistency pow to enable usrloc db_insert_update in a dmq replicated environment, where all registrars share the same db. I'm already using the filter option to avoid loading/deletion by server id, but there's no similar option for writing. I know that it is possible to use db mode 4 on all registrars (which get synced by dmq) except one, which will be responsible for writing, but this creates a little unbalanced setup in addition to performing writes only from one proxy. Any hint? Maybe is time to check how to filter writes, too :) ? Thanks, Matteo

How to externally trigger htable cache flushing?
by Benoit Panizzon 18 Jul '22

18 Jul '22

Hi List We cache stuff like call forwarding information in a htable cache to minimizie SQL lookups and have it available via DMQ on all instances. But of course, if the call forwarding information for a destination changes in the database, we would like to flush either the whole cache, or even better, that single entry. What is the best way to do this?

dialog timeout_avp no longer works?
by Alex Balashov 18 Jul '22

18 Jul '22

Hi, I discovered recently that, on Kamailio 5.5.4 at least, the dialog ’timeout_avp’ no longer appears to have effect. Here are my (seemingly relevant) dialog parameters: modparam("dialog", "enable_stats", 0) modparam("dialog", "hash_size", 4096) modparam("dialog", "rr_param", "dlgcor") # DLG "correlator" modparam("dialog", "dlg_flag", 2) modparam("dialog", "default_timeout", 28800) # 8 hours modparam("dialog", "dlg_match_mode", 1) modparam("dialog", "table_name", "dialog") modparam("dialog", "send_bye", 1) modparam("dialog", "wait_ack", 0) modparam(“dialog”, “timeout_avp”, “$avp(dlg_timeout)”) The flow is roughly like this: request_route { ... t_check_trans(); if(is_method(“INVITE”)) { ... dlg_manage(); $avp(dlg_timeout) = 10; ... if(!t_relay()) sl_reply_error(); return; } I was able to resolve the problem by switching to dlg_set_timeout() instead, but I wonder if there has been a regression. Last version I have on which this positively works is 4.4.7, though, so not sure when it might have broken. One nuance: $avp(dlg_timeout) is not initialised prior to calling dlg_manage(), and the value is only set if certain conditions are true. Not sure if some stricter check appeared in later releases which could cause this to be a problem.

Nathelper sip ping and Path support ?
by matteo brancaleoni 18 Jul '22

18 Jul '22

Hello, I'm trying to setup the following scenario with sip ping: UAC -> Kamailio Edge -> Kamailio Registrar Edge proxy is a multihomed proxy with public/private ips and the registrar is a kamailio on a private network. The edge acts as a nat proxy and loadbalancer. Edge proxy inserts a Path header (and contact alias) which get correctly saved on registrar usrloc. Registration works as expected. Now, since I need to keep nat open towards the uacs and expire them when they're not reachable anymore, I'm trying to send sip pings from the registrar via the edge proxy. I'm using nathelper sipping in the registrar. What I see is that the registrar sends out a sip options putting in the Route header the Path as expected, but the sip packet gets sent directly to the UAC contact and not via the edge, as the Route header specifies. After looking into the nathelper code, it seems that the sip packet is sent via udp directly without any specific routing. So the question: it should work what I'm trying to achieve? Maybe not? Probably I can work around it setting the ;received in the contact on registrar (it will set to the edge proxy) and since the contact is aliased on the edge when the edge receives an option from the registrar it can process the alias and send it to the correct endpoint, but seems a workaround? Or using the keepalive module maybe, even if that means setting specific timers and manually do what the nathelper module already does? Any hint? Thanks, Matteo

Does pure outbound RFC5626 work without edge proxies?
by Richard Chan 17 Jul '22

17 Jul '22

Hi sr-users, Does pure RFC5626 outbound work without an edge proxy->internal proxy design? By "pure" I mean no nathelper to rewrite addresses. I tried setting up the following: Configuration: use standard kamailio configuration without WITH_NAT (Ignore RTP-rtpengine/rtpproxy for the moment as I am just testing the control plane) 1. UA1 UA2 each behind NAT, with bogus Contact: headers 2. kamailio loaded with rr/tm (no outbound/path because I am using single proxy/registrar — without edge proxies) 3. no nathelper: no Contact rewriting, set_contact_alias etc 4. Both UA1 and UA2 establish persistent TLS to kamailio 5. INVITE/200 OK/ACK does work. 6. Contact headers show the NAT bogus addresses (as expected). UA1/UA2 are configured to be "dumb"(i.e. don't self-rewrite Contact:/SDP based on rport/received). Problem: 7. In-dialog requests don't work as kamailio tries to route to the bogus addresses per the Contact header. I.e. kamailio doesn't seem to resolve the UAs(bogus Contact addresses) to the persistent TLS connections. Now in the Route header I don't see any flow-token so probably kamailio is doing "normal" routing instead of RFC5626 routing (i.e. because it has no flow-token to match with an existing flow). This leads me to ask: for pure RFC5626 to work (no nathelper stuff at all) is it a must that there is a "edge-proxy--[1]-->internal-proxy" layout? ...and...the flow-tokens in [1] are what make it possible to skip bogus Contact: header and route to an existing flow? Regards Shih-Ping Chan

usage of {s.urldecode.param} to convert special chars (why is + removed?)
by Benoit Panizzon 14 Jul '22

14 Jul '22

Hi List Service Numbers, like to activate CFW probably often start with * and end with a # # is a special character that needs to be urlencoded in an SIP URI. So best would be to use a generic kamailio urldecode transormation. I guess {s.urldecode.param} is what I was looking for. So when I get a call to the 'enable CFW' service I get $rU => "*21+419999999%23" So I want to extract the destination number and remove the urlencoded # sign. So I do $var(cfw-dest) = $var(cfw-dest) = $rU; $var(cfw-dest) = $(var(cfw-dest){s.substr,3,0}); # "+419999999%23" $var(cfw-dest) = $(var(cfw-dest){s.urldecode.param}); But now I end up with 419999999# the + sigh disappeared. Is this expected behavior? How would this be done the correct way?

Need Suggestion/Idea to set call limit on 3 kamailios.
by Waqar 40 13 Jul '22

13 Jul '22

Please Read the Scenario in full and then guide me. In my scenario, I have three Kamailio (KamA, KamB, KamC) running in production. They do load balancing for the asterisks which are about 9. Kamailios randomly receive calls from the SIP trunk. I have set the limit of 750 calls on each kamailios. I want to provide only 1000 Calls to my client but they are enjoying calls more than this since each kamailio can receive 750 calls (I have set this limit for redundancy purpose). And I cannot set the limit like 750 on KamA and the rest on KamB and KamC for redundancy purposes. If one kamailio goes down then they send calls on the other kamailios so that no call drops. So, I want to know if there is a module or a way that my redundancy is not affected and I limit total calls on the three kamailios to not exceed 1000. Waiting for a prompt response. Let me know if you need any further information. Regards, Vicky

Multiple rtpengine servers
by David Cunningham 07 Jul '22

07 Jul '22

Hello, We are looking to implement a system with one Kamailio server and multiple rtpengine servers. I see that the rtpengine module allows the server configuration to be stored in a database table with multiple entries, which is perfect. My question is - how does Kamailio distribute load between multiple rtpengine servers in the same set? If one of the rtpengine servers goes offline then will Kamailio note this and not send calls to that server until it comes back online? If not then presumably calls could be delayed by whatever the timeout for accessing a server is? Thank you very much, -- David Cunningham, Voisonics Limited http://voisonics.com/ USA: +1 213 221 1092 New Zealand: +64 (0)28 2558 3782

Kamailio 5.5 STIR SHAKEN private key buffer size error

Re: [SR-Users] mhomed not working for tls destination
by Aidar Kamalov 05 Jul '22

05 Jul '22

Hi, thank you for your reply, I have tried it at kamailio 5.5 and 5.6 versions, and there are two network interfaces. Actually, I have created a testing vm for this, with a simple almost default kamailio configuration. And yes, with forcing socket everything is working fine, but I just want to know maybe there is a kamailio params that allow "mhomed" params to work with tcp/tls destinations, or is it impossible by TCP design, or is it a kamailio bug. I wonder if anyone uses kamailio with 2+ network interfaces and uses tls and don't use $fs? -- Aidar

return 0 is not equivalent to exit
by Patrick Karton 04 Jul '22

04 Jul '22

on 5.5 kamailio wiki for core it is stated that return (0) is the same as exit. but that's not true request_route { if (route(POS)){ xlog("POS PASS\r\n"); } if (!route(NEG)){ xlog("NEG PASS\r\n"); } if (!route(ZERO)) { xlog("ZERO PASS\r\n"); } xlog("AFTER ZERO\r\n"); send_reply("400","Error"); return; } route[POS]{ return 1; } route[NEG]{ return -1; } route[ZERO] { return 0; } for example from the config above not only ZERO PASS will be printed but also all the actions after route(ZERO) are still executed. instead if i replace return 0 with exit in route[ZERO]. this work as expected.

mhomed not working for tls destination
by Aidar Kamalov 04 Jul '22

04 Jul '22

Hello, I have faced an issue when mhomed parameter working well only for udp destinations in systems with multiple network interfaces. If kamailio forward call to the UDP destination, mhomed option chooses the correct Via and the correct network interface for sending. But if the destination is tls, mhomed chooses first described in configuration file "listen=" interface and use this IP in Via header Network routes in the system are correct and "ip r get IP" returns the correct route and interface. Should mhomed work with tcp/tls or is this impossible with TCP design? -- Aidar

Question about SIP registration
by Cheng Tang 01 Jul '22

01 Jul '22

Hi, everyone! In one sentence, I want to know how to how to add the shared key (aka. K, Ki) used by AKA algorithm to Kamailio. I’m using Kamailio as an IMS server to test my own 5G Core. As you know, UE would send its first SIP Registration message to Kamailio with its IMPI and IMPU, then Kamailio should use the shared key to proceed AKA algorithm to generate the authentication vector, then respond UE with 401 unauthorized message to challenge the UE. I’ve done my research and I still can’t figure out how to let Kamailio know this shared key. And when I was doing my test, it seems like Kamailio used some default key to generate the auth vector. Could anybody help me? I’ve been stuck here for days.

Run PCSCF without IPSec
by Weiqi Yao 30 Jun '22

30 Jun '22

Hello Community, We are running Kamailio with 3 instances as PCSCF/ICSCF/SCSCF, and we don't want IPsec to be used in between PCSCF and UE and we confirmed the initial Register UE send do not have the Security-Client header. However, seems the IPsec is enabled by default in current PCSCF cfg, we tried to comment WITH_IPSEC as well as couple ipsec_forward function out in the cfg, but when the 401 Challenging message send to PCSCF and PCSCF failed to forward it to UE due to (Create ipsec failed) reason. So I want to reach out and see if anyone have experience not using IPsec with currently Kamailio PCSCF? Any clue or comment will be appreciated! BR, Weiqi

Install Kamailio in captive network
by Rahul mm 30 Jun '22

30 Jun '22

Hello guys, Ab initio, I'm loving Kamailio and the endless horizons it opens-up. Is there any document somewhere to get Kamailio installed in a captive network that runs w/o internet? I know this seems bizarre but in the mining industry most of the locations do not have internet facilities but they still want to use VoIP. I do not have the privilege to pull a blade system and put it on the internet to install Kamailio, FS etc. Any suggestions? -- Warm Regds. MathuRahul

Forward reply in onreply_route
by Carsten Bock 29 Jun '22

29 Jun '22

Hi, Question: Is there a way to forward a reply from the reply route and do other stuff afterward? We are currently doing operations on a 183 reply and it would be useful if we could forward the reply before continuing to process other stuff. High-Level example: *route { t_on_reply("REPLY"); t_relay();}onreply_route[REPLY] { // Forward the reply to the Caller t_relay(); // Does not work, as t_relay is only allowed in request and failure-routes // Do other fancy stuff, e.g. a DB Update or anything else}* Any ideas?

SIP Proxy Challange
by Mihai 27 Jun '22

27 Jun '22

Hello ! I have this issue with the telco provider they give the sip trunk on a private connection with private ips, the problem is that i am trying to relocate the sip trunk in remote server and I've tried though basic networking/tunnels/vpn and no go; their sbc is dropping requests and rejects if they are more via headers, they force me to use that connection and the ip allocated. The challenge is how to do this in kamailio, basically I just want to transport the trunk (similar to a reverse proxy for web) to its new destination and from there handle everything. Any hints on how to achieve this?

How to handle a 301 redirect request from a client?
by Benoît Panizzon 27 Jun '22

27 Jun '22

Hi Gang We want to allow customers to send a 301 to forward calls to mimik ISDN PARE. The new destination is in the contact user HF. So I guess I could handle this on the t_on_failure route to catch that error, extract the contact user HF, craft an appropriate Diversion header and send the call on. But I wonder, is there maybe a module which handles all of this out of the box? -- Mit freundlichen Grüssen -Benoît Panizzon- @ HomeOffice und normal erreichbar -- I m p r o W a r e A G - Leiter Commerce Kunden ______________________________________________________ Zurlindenstrasse 29 Tel +41 61 826 93 00 CH-4133 Pratteln Fax +41 61 826 93 01 Schweiz Web http://www.imp.ch ______________________________________________________

Append (not replace) line to SDP body
by Benoît Panizzon 24 Jun '22

Hi Gang Next question. I have some broken CPE which do not set a=ptime despite using 20ms which then causes the call to get rejected in certain destinations, because ptime header is missing. So I would like to match the user-agents in question and add back a=ptime:20 Google searches found an user with the exact same problem almost 10 years ago and Daniel replying that indeed a function to add a body line would be handy. https://www.kamailio.org/docs/modules/devel/modules/textops.html How could this be accomplished? I don't see a add_body_line or other function which does not 'replace' a body line. -- Mit freundlichen Grüssen -Benoît Panizzon- @ HomeOffice und normal erreichbar -- I m p r o W a r e A G - Leiter Commerce Kunden ______________________________________________________ Zurlindenstrasse 29 Tel +41 61 826 93 00 CH-4133 Pratteln Fax +41 61 826 93 01 Schweiz Web http://www.imp.ch ______________________________________________________

Finding advertised address of socket
by Tor Petterson 24 Jun '22

24 Jun '22

Hi I have a setup where Kamailio is connected to several telephony providers using different IP addresses to communicate with them. So I have a socket per provider. I am using the dispatcher module to route calls to the different providers. My question is if there is a way to get the advertised address of the socket chosen by dispatcher? I have a socket pointer in the XAVP, but I can't figure out if it is possible to get the advertised address from it somehow. Thanks in advance. Tor

Testers wanted for new TLS transport based on wolfSSL
by Richard Chan 24 Jun '22

24 Jun '22

Hello Kamailio users, I would like testers to try out a new module tls_wolfssl, an alternate TLS transport based on wolfSSL. Why another TLS transport implementation? The travails of using OpenSSL >= 1.1.1 in Kamailio’s multi-process paradigm has been documented by OpenSIPS (and that sister project has implemented tls_wolfssl). Essentially, OpenSSL makes no concessions to the multi-process use case and in fact has implementation details that work against global shared memory structures. As a result Kamailio contains some tricky code * a pthread polyfill in core * duplicated SSL_CTX per worker * atexit workaround How to test? The code is currently in master and can be built in the usual way. Debian has 5.2.0 libwolfssl-dev needed; for some RPM distros (el8, el9, fc36) I have created a Copr repository https://copr.fedorainfracloud.org/coprs/beaveryoga/wolfSSL/ Known limitations The current state can be considered as identical to tls+OpenSSL 1.1.1/3.0.x. Old TLS protocols < 1.2 and cipher list configuration don’t work, i.e., only TLS 1.2 and 1.3 work with the default cipher list. In your configuration just replace loadmodule “tls.so” with loadmodule “tls_wolfssl.so” The rest of the TLS configuration can remain unchanged unless you are using a funky protocol version/cipher list combination. Thanks! S-P

Possibility of mirroring the rpm/deb.kamailio.org repos efficiently via rsync?
by Malte Schmidt 23 Jun '22

23 Jun '22

Hello, is there an rsync endpoint available or is there a possiblity of setting this up? Creating a mirror via HTTP is a rather quick and dirty solution and while the deb-repo can be mirrored using debmirror, the rpm repo is hard to sync to a non-CentOS-based machine due to missing dependencies such as yum and reposync in latest Debian-based systems. Would be great to get some input in regards to this topic. Cheers

What is the alignment of shm_malloc and friends?

22 Jun '22

Hi Daniel and kamailio users, In my integration adventure of wolfSSL and kamailio I have encountered an alignment issue sometime causing segfaults. May I enquire what is the alignment of shm_malloc and friends? The wolfSSL library integration requires that ser_malloc and ser_realloc return values aligned on alignof(_max_align_t) which in the case of x86_64 is 16. Thank you Shih-Ping

Record-Route advertised per branch
by Ilie Soltanici 17 Jun '22

17 Jun '22

Hello, Is there any way to advertise a different IP Address in the Record-Route header individually per branch? I have a setup here - where Kamailio is listening on 2 different interfaces: Local IP and External IP. At the moment if the packet is coming through the internal interface - I'm checking where is it going to and based on that I'm setting the Record-Route header accordingly - and everything works well, except when I have multiple branches: one going through the internal interface and another one through the external one, so in this case, I have to add a different record-route header per branch, by doing this in the branch_route - it's not working and getting the error: w_record_route_advertised_address(): Double attempt to record-route. What would be another way to accomplish this?

Kamailio eats pkg mem, but where?
by Sebastian Damm 14 Jun '22

14 Jun '22

Hi, we have some Kamailio instances running (currently latest 5.4 release), and we need to restart it from time to time. We have a grafana graph showing the pkg memory usage of one random tcp listener, and it increases slowly over time. Config is pure python KEMI. A mem dump directly after restarting Kamailio says this: SipSeppBook22:tmp sdamm$ grep alloc pkgmem_before.log | awk '{ print substr( $0, 16, length($0) ) }' | sort | uniq -c | sort -k1n | tail -10 16 sipproxy qm_status(): alloc'd from core: core/re.c: subst_parser(301) 31 sipproxy qm_status(): alloc'd from core: core/sr_module.c: load_module(436) 31 sipproxy qm_status(): alloc'd from core: core/sr_module.c: register_module(236) 31 sipproxy qm_status(): alloc'd from core: core/sr_module.c: register_module(253) 40 sipproxy qm_status(): alloc'd from core: core/pvapi.c: pv_init_buffer(2139) 58 sipproxy qm_status(): alloc'd from core: core/cfg.lex: pp_define(1827) 133 sipproxy qm_status(): alloc'd from core: core/rpc_lookup.c: rpc_hash_add(101) 162 sipproxy qm_status(): alloc'd from core: core/counters.c: cnt_hash_add(339) 211 sipproxy qm_status(): alloc'd from core: core/cfg.lex: addstr(1448) 265 sipproxy qm_status(): alloc'd from core: core/pvapi.c: pv_table_add(236) And after running for some weeks, the same dump looks like this: SipSeppBook22:tmp sdamm$ grep alloc prod_pkgmem.log | awk '{ print substr( $0, 16, length($0) ) }' | sort | uniq -c | sort -k1n | tail -10 31 ifens5 qm_status(): alloc'd from core: core/sr_module.c: register_module(253) 40 ifens5 qm_status(): alloc'd from core: core/pvapi.c: pv_init_buffer(2139) 59 ifens5 qm_status(): alloc'd from core: core/cfg.lex: pp_define(1827) 133 ifens5 qm_status(): alloc'd from core: core/rpc_lookup.c: rpc_hash_add(101) 161 ifens5 qm_status(): alloc'd from core: core/counters.c: cnt_hash_add(339) 203 ifens5 qm_status(): alloc'd from core: core/cfg.lex: addstr(1448) 265 ifens5 qm_status(): alloc'd from core: core/pvapi.c: pv_table_add(236) 686 ifens5 qm_status(): alloc'd from core: core/pvapi.c: pv_parse_format(1173) 694 ifens5 qm_status(): alloc'd from htable: ht_var.c: pv_parse_ht_name(158) 707 ifens5 qm_status(): alloc'd from core: core/pvapi.c: pv_cache_add(349) I know, currently there are a few lines in the code which look like this: self.instance_name = KSR.pv.get("$sht(pbxdata=>ip.%s)" % (ip,)) This has been an issue in the past and I have replaced the code with something like this: KSR.pv.sets("$var(tmpInstanceIp)", ip) self.instance_name = KSR.pv.get("$sht(pbxdata=>ip.$var(tmpInstanceIp))") However, even after changing this, the memory still grows slowly but steadily. The usage scenario is TLS-only on one side (clients) and TCP-only on the other side (pbxes). Does anybody have a hint for me how to debug this? Looks like there's a lot of pv stuff in the memory, but I don't really know where. Thanks for any hints, Sebastian

I need to hang up a call after some seconds after received 183 provisional response but before any other SIP message. I am using "rtimer" module to set a callback on time, but how can I search for a call on transaction module in order to terminate the call? I think I am missing something to prepare the transaction data before I can use this data to terminate the call. I am thinking of storing the call-Id of all transactions to use on timeout callback, I don't know if it's possible. Thanks in advance. Antonio

Get all contacts by domain
by Jose Fco. Irles Durá 13 Jun '22

13 Jun '22

Hi, I'm running a cloud infrastructure with multiple sip domains and I have some kamailio's as registrars with dmq for usrloc replication. The kamailio registrars are configured without db, so the aors are in ram. For some gui's I need to get all aors for one sip domain, If I execute ul.dump I get all aors, but I want only a few. In my situation it would be perfect to get all registrations for one sip domain in one request (memory, performance, cache at gui...) I thought I could save the registers with save("$rd") but ul.dump doesn't allow any parameter that restricts the "location" domain. Is there any solution for this? Best regards -- Jose Fco.

Use of interface name or listening socket name as DMQ server_socket
by Ben Kaufman 10 Jun '22

10 Jun '22

Kamailio allows the use of an interface name (eth0 for example), as the identifier for the listen directive. Additionally it allows assignment of a name to be used as an identifier. This can be used, as indicated in the documentation: A unique name can be set for sockets to simplify the selection of the socket for sending out. For example, the rr and path modules can use the socket name to advertise it in header URI parameter and use it as a shortcut to select the corresponding socket for routing subsequent requests. I'm wondering if there is a way to get allow either of these parameters to be used to define DMQ's server_socket parameter. This would be useful in containerization situations where the local IP address is assigned dynamically. Here's what I'm attempting: #!KAMAILIO loadmodule "tm" loadmodule "sl" loadmodule "dmq" loadmodule "textops" listen=udp:eth0:5060 name "sip5060" listen=udp:eth0:5090 name "sip5090" modparam("dmq", "server_address", "sip:dmq_quicktest:5090") modparam("dmq", "notification_address", "sip:dmq-bus:5090") modparam("dmq", "server_socket", "sip5090" ) ## Above line doesn't work, neither does the line below: #modparam("dmq", "server_socket", "udp:eth0:5090" ) modparam("dmq", "multi_notify", 1) modparam("dmq", "num_workers", 3) modparam("dmq", "ping_interval", 30) request_route { exit; } I get the following error during startup: 0(1) ERROR: dmq [dmq.c:241]: mod_init(): server_uri is not a socket the proxy is listening on Thoughts? I realize that I can configure and pass static networking with the containers, but I'm looking for a way to have this set on the fly - especially when testing, etc. Ben Kaufman

Hello ! I have this issue with the telco provider they give the sip trunk on a private conection with private ips, the problem is that i am trying to relocate the sip trunk in remote server and I've tried though basic networking/tunnels/vpn and no go; their sbc is dropping requests and rejects if they are more via headers, they force me to use that conection and the ip allocated. The challenge is how to this is in kamailio, basically i just want to transport the trunk (similiar to a reverse proxy for web) to its new destination and from there handle everything. Any hints on how to achieve this?

Hello, I'd like to remove headers during async processing e.g. in a route called from http_async_client(..). The usual textops functions are not working here. Adding headers could be done using something like rtjson, but it do not offer a remove header function. I could of course loop the request locally, but this is not that "nice". Any other suggestions for this case? Or just the rtjson module needs some extensions?

Siremis startup helper service for systemd
by Joseph Goettgens 09 Jun '22

09 Jun '22

Hi, I had some difficulties getting Siremis 5.3 to run under Debian 11 Bullseye. It turned out that the problem was the creation of the Siremis socket: <UnixSockLocal name="unixsocklocal" address="/run/siremis/siremis_rpc.sock" timeout="3.0"/> There is a warning in siremisJRCommands.xml that points out that systemd has to be reconfigured as sockets in /tmp are no longer shared (PrivateTmp setting). By the same token, /run/siremis/siremis_rpc.sock cannot be created as the httpd server is not allowed to write to /run, i.e. it can neither create the socket nor the siremis directory. The permanent creation of the siremis directory with suitable access rights is also not possible, since /run is mounted as tmpfs in the default configuration. At least the directory has to be created at boot time, which can be done with a small helper service. This is working for me (siremis-helper.service): [Unit] Description=Siremis Helper Service After=network.target [Service] Type=oneshot ExecStartPre=/usr/bin/mkdir /var/run/siremis ExecStart=/usr/bin/chown www-data:www-data /var/run/siremis [Install] WantedBy=multi-user.target It is enabled the usual way with systemctl "systemctl start --now siremis-helper". Siremis now works with jsonrpc commands and the procedure would mean that installing Siremis on a newer Debian system would definitely require some attention. Does anyone have any objections to the above procedure?

This is a hardcoded value that can't not be changed. Regardless of the traffic that flows through the connection, it is closed after 10 minutes. Problem: in case of long-running calls above 10 minutes it is not possible for Kamailio to send back SIP traffic back to the client using the original TCP connection. The client has been asked to either increase the time limit or send SIP reinvites - none of that is possible due to some client's infrastructure limitations. Question: is it possible to force Kamailio to open a new TCP connection and associate it with the call? Client has a 5060 port always opened which can accept incoming connections.

ipops dns_query not working using Kemi
by Thomas de Rooij | CM.com 09 Jun '22

09 Jun '22

Hi all, We are trying to do a DNS query using Kemi: KSR.ipops.dns_query(domain, "xyz") The result is always -3. This is returned here: https://github.com/kamailio/kamailio/blob/5.5.4/src/modules/ipops/ipops_pv.… It seems weird to me that the error code is returned because the same non-Kemi code works just fine. Could it be related to this issue: https://github.com/kamailio/kamailio/issues/2052 Thanks. Kind regards, Thomas

Siremis JSONRPC problem on Bullseye
by Joseph Goettgens 07 Jun '22

07 Jun '22

Hi, I seem to have a problem setting up Siremis 5.3 on a Debian 11 box using the Kamailio 5.6.0 release (installed from repo). When I enter something like core.uptime into the JSONRPC Command Panel, I get a "System Internal Error" alert. The Apache error log then says: [Mon Jun 06 10:48:41.459377 2022] [php7:notice] [pid 22322] [client 192.168.xxx.xxx:45030] socket bind failed: No such file or directory, referer: http://deb11srv1-kamailio/siremis/sipadmin/jrcmds The path siremis/sipadmin/jrcmds obviously does not seem to exist and I assume that one needs some internal adjustments for some paths. As far as the socket is concerned, siremis/modules/sipadmin/service/siremisJRCommands.xml has the definition: UnixSockRemote name="unixsockremote" address="/var/run/kamailio/kamailio_rpc.sock" timeout="3.0"/> and the corresponding definition in /etc/kamailio/kamailio.cfg is: modparam("jsonrpcs", "dgram_socket", "/var/run/kamailio/kamailio_rpc.sock") modparam("jsonrpcs", "dgram_mode", 0666) which looks fine to me. I also checked for the existence of the socket and its access rights. Any suggestions?

t_cancel_callid - doesn't insert Reason header, if called from branch 0
by Pavel Veselovsky 07 Jun '22

07 Jun '22

Hallo all, I defined branch_failure routing block via t_on_branch_failure() In the branch_failure route, in case of "408 Request timeout" I am sending CANCEL with reason "t_cancel_callid("$ci", "$cs", "22", "408")". If the t_cancel_callid("$ci", "$cs", "22", "408") is called in branch_failure for branch idx 0, the CANCEL is sent, but Reason header is missing there. Why? (I expect that t_cancel_callid() should insert Reason header regardless of branch it is called from) If the t_cancel_callid is called in branch idx !=0, the CANCEL contains Reason header with cause as expected. Thanks for clarification of this behavior, Pavel. P.S. code snipset: event_route[tm:branch-failure:primary] { if ($T(reply_code) == "408") { if ($avp(branch_idx) == $T_branch_idx) { if (t_cancel_callid("$ci", "$cs", "22", "408")) { xlog("L_INFO", "CANCEL sent ci:$ci, cs:$cs 408"); } else { xlog("L_INFO", "CANCEL not sent ... ci:$ci, cs:$cs 408"); } $var(_palotmp_) = "sip:" + $avp(replaced_cfnry_target_number) + "@" + $dd + ":" + $dp + ";user=phone"; append_branch($var(_palotmp_),"1.0"); t_relay(); return; } } }

SNMP, export concurrent calls count
by ZZ Wave 30 May '22

Hello. Debian 10, Kamailio 5.2.1 I want to monitor concurrent calls in/out per every trunk connected to this proxy (it's done with dialog profiles), and export this to Zabbix. But I can't find in snmpstats documentation how to export user-defined variables. Help me please. Maybe SNMP isn't the best solution for that...

DNS Failover try next destination on receiving code other than 503
by Patrick Karton 30 May '22

30 May '22

Hello, im using DNS Failover and everything works well except i would like to try other resolved ips when i receive a 408 from the previous ones As far as i know only a received 503 will trigger next destinations and there is no config parameters in tm module to handle that behaviour. so how can i implement it ? set a failure route before relay and just call t_relay() after again ? also is there a way in failure route to know how many destinations are left to exit failure route. Thanks for help.

KEMI Python Syntax
by Olivier Roy 30 May '22

30 May '22

Hello, I am writing some Kamailio scripts using app_python3. I understand that the KSR module is automatically generated by Kamailio. So when I import KSR from KSR I don't get any syntax from my IDE since it doesn't know where KSR is. My question: is there a way to generate a KSR.py file that can be used for autocompletion and syntax highlighting? Thanks. Olivier

Find Values in User part of Diversion URI
by Lewis Hutchinson 30 May '22

30 May '22

Sorry if this is a super basic ask but I can't seem to work it out, I have got a work around but for my own sanity wanted to post the question on here. In Kamailio Native 5.5.2 I want to be able to look into this field $(di{uri.user}) and "find" or see if it "contains" a value i.e Diversion: "TEST" sip:112233445566@xxx.xxx.xxx.xxx;user=phone; find 234 or contains 234 I know how to do this in in KEMI Python but for the life of me cant get my head around it in Native. 2ndly is there an opposite to {s.numeric} Removes all non-numeric parts of string. I want the ability to strip all numeric parts. Keep us the good work. Lewis

TLS connection failure. Not sure if system behavior is correct.
by Володимир Іванець 27 May '22

27 May '22

Hello all! My test Kamailio setup (now updated to version 5.5.4) that was working with MS Teams some time ago, now stopped :) I was wondering if someone could tell me if the current behavior is correct or if there is a problem? Here is a screenshot of the packet capture: [image: image.png] I thought that after MS Teams side sent Change Cipher Spec request, Kamailio should respond with ACK. But instead it just starts sending data (I believe it sends OPTIONS request. sipdump module captured it). Is this correct? There seems to be no issues in the Kamailio debug log: May 20 15:29:05 server kamailio[28961]: 14(28975) DEBUG: <core> [core/io_wait.h:782]: io_watch_chg(): DBG: io_watch_chg (0xae9560, 24, 0x1, 0xffffffff) fd_no=20 called May 20 15:29:05 server kamailio[28961]: 14(28975) DEBUG: <core> [core/io_wait.h:600]: io_watch_del(): DBG: io_watch_del (0xae9560, 25, -1, 0x0) fd_no=20 called May 20 15:29:05 server kamailio[28961]: 14(28975) DEBUG: <core> [core/tcp_main.c:4471]: handle_tcpconn_ev(): sending to child, events 1 May 20 15:29:05 server kamailio[28961]: 14(28975) DEBUG: <core> [core/tcp_main.c:4144]: send2child(): selected tcp worker idx:1 proc:11 pid:28972 for activity on [tls:172.16.30.206:5062], 0x7fad6a70f6c8 May 20 15:29:05 server kamailio[28961]: 11(28972) DEBUG: <core> [core/tcp_read.c:1737]: handle_io(): received n=8 con=0x7fad6a70f6c8, fd=6 May 20 15:29:05 server kamailio[28961]: 11(28972) DEBUG: tls [tls_domain.c:1208]: tls_lookup_private_key(): Private key lookup for SSL_CTX-0x7fad6a5e1eb8: (nil) May 20 15:29:05 server kamailio[28961]: 11(28972) DEBUG: <core> [core/tcp_main.c:2720]: tcpconn_do_send(): sending...

Debian: Kamailio: -> FIN - SYN -> on new port
by Kevin Browne 26 May '22

26 May '22

Hi, am looking for some specific Kamailio help i cant seem to find anywhere ( # running Kamailio on Debian/buster ... ## after receipt of tcp FIN, port is closed. when signaling is required again from Kamailio side. Kam is attempting SYN on FINd (closed) port. this is rejected RST. How to change SYN to re-establish tcp on new ephemeral port? ## another description, same problem: FIN received from (external) cisco (call owner) due to port recycling, not to keep port open after x minutes. everything is as expected re ACKs and such. When Kam wants to send REFER to cisco after the FIN, tcp attempts a SYN (as we'd expect) but sends SYN on old closed port. ## Where to change this Kam/OS/other is where i'm attempting to identify, then figure how to change. Thank you.

TOPOS + RE-INVITE problem - Contact IP not updated
by c c 24 May '22

24 May '22

It seems that TOPOS is not working properly on RE-INVITE and stop masking IP and contact on some RE-INVITE. When a RE-INVITE is send with Kamailio IP as Request-URI TOPOS is not operating. Note : we are using the HTABLE trick to rewrite $ru and match the call but we would need to have TOPOS re-evaluating the dialog once done. We use a standard configuration with 2 modifications. 1. in route[DISPATCH] to set the HTABLE if(is_method("INVITE")) { $sht(ct=>$ci::$ft) = $sel(contact.uri); } 1. in route[WITHINDLG] to find the call if R-URI = myself if(has_totag() && uri==myself) { if($sht(ct=>$ci::$ft) != $null && $T_reply_code > 400) $shtex(ct=>$ci::$ft) = 10 ; if($sht(ct=>$ci::$tt) != $null) { $ru = $sht(ct=>$ci::$tt); if (is_method("BYE")) $shtex(ct=>$ci::$tt) = 10 ; route(RELAY); } } As you can see in the PCAP the RE-INVITE goes directly to calling stating with the Contact not updated and the 200 OK is also sent to called party with wrong Contact info too. [ https://github.com/kamailio/kamailio/files/8730489/topos-issue.zip ] This behavior breaks the BYE procedure. Any advice ? Chris

Releasing Kamailio v5.6.0
by Daniel-Constantin Mierla 23 May '22

23 May '22

Hello, with some effort directed lately to convert the wiki content to markdown files and host them on github, it's time to now to nail down the path to release nest major release for Kamailio, respectively v5.6.0. What's new in this major release as well as upgrade guidelines have to be built, but I hope to be done in time to release Kamailio v5.6.0 either on Monday, June 23, 2022 or on Wednesday, June 25, 2022. Should anyone consider a different release planning, let's discuss it. If anyone wants to help with them, the content has to be added to the github wiki repository: * https://github.com/kamailio/kamailio-wiki If not there, new files have to be created and linked from the main page. The wiki is built with mkdocs into html and made available for browsing at: * https://kamailio.org/wikidocs/ Cheers, Daniel -- Daniel-Constantin Mierla -- www.asipto.com www.twitter.com/miconda -- www.linkedin.com/in/miconda Kamailio Advanced Training - Online: June 20-23, 2022 * https://www.asipto.com/sw/kamailio-advanced-training-online/

Hi, You are currently using TLSv1/SSLv3 ECDHE-RSA-AES256-GCM-SHA384 256 Teams stopped using TLSv1/ TLSv1.1 and only allowing TLS1.2+ So change your kamailio TLS settings to enforce only it method = TLSv1.2+ After restarting kamailio your team's connections should be good. -- Best Regards, Ahmed Fouad

Path MTU issues over UDP/IPv6
by Rick van Rein 20 May '22

20 May '22

Hello, IPv6 routers never fragment packets. Rather, they drop a packet that is too large for a (local) MTU and send back ICMPv6 "Packet Too Big". This seems to cause loss of larger SIP messages when an ISP tunnels their IPv6 at the expense of the MTU. The pmtu_discovery flag sets Don't Fragment in IPv4 traffic; in IPv6 this is an implied property. Does Kamailio learn a lower MTU from any "Packet Too Big" for IPv6 even if pmtu_discovery is not set? Future resends can then be fragemented appropriately. The udp_mtu setting diverts to another protocol, but that would be a setting as low as the worst peer, impacting all. It would be a weird struggle with a telco serving many. PMTU would be better to rely on, but how does it work in Kamailio? Details on https://www.rfc-editor.org/rfc/rfc3542#section-11.3 https://stackoverflow.com/questions/38817837/how-does-mtu-retransmission-wo… Thanks, -Rick

Forwarding SIP status code to HTTP client
by Tim Anderson 19 May '22

19 May '22

Hi, I have a kamailio that is has an HTTP message server. Is it possible to send the SIP status code back in the HTTP reply? Is it possible to suspend an xhttp request while some other stuff happens and then send the reply later? The relevant bit of the config currently looks like event_route[xhttp:request]{ if($hu == "/sms"){ $uac_req(method)="MESSAGE"; $uac_req(ruri)="sip:1234@example.com"; $uac_req(furi)="sip:4567@example.com"; $uac_req(turi)="sip:1234@example.com"; $uac_req(body)=$rb; uac_req_send(); xhttp_reply("200", "OK", "text/plain", "Sent") } } Regards, Tim

Kamailio Stop Responding Randomly
by M Arqum CH 19 May '22

19 May '22

Kamailio first gives timeout on ctl unix socket as I am exporting data using prometheus exporter, after a few minutes it stops responding to any sip request on default/production udp port binded with multiple IP addresses for sip traffic. The other listing port which is used by keepalived check script for bing-pong keeps responding to option messages. Its very random behaviour occurs after a few days or after a few months, the system having max load 350 concurrent calls with load average 200-300. I am attaching core dump which is collected before restarting the process.

Split audio and video into different calls
by Rüdiger, Christoph 18 May '22

18 May '22

Hi everyone, we are running a call center with really good to use hardphones and audio only up to this point. Because of changing regulation, we soon have to deal with video calls as well, but only for a fraction of the calls (below 1%). Instead of switching everyone to clumsy softphones for the rare case of a video call, I’m exploring the ability to branch an incoming call into a pure audio call to the hardphone and optionally a pure video call to the softphone. Has anyone done this in the past and can share some experiences/ideas on 1. Can it be done purely with Kamailio and rtpengine? I don’t have a clear picture of how to do it purely with Kamailio on the SIP side, because we end up with two independent legs (to the hardphone and the softphone). Or do I need to deploy an Asterisk, Yate, freeswitch, etc. and doing it as a 3-way conference where one party gets both RTP streams (the trunk) and the other two parties only get one RTP stream (either audio or video)? 2. Was it worth the effort or a steady candidate for troubles? I’m looking forward to your thoughts, especially on question b).

kamailio WebSocket not respond sometimes
by dolphin 18 May '22

18 May '22

Hello, kamailio could not respond to the question: This machine is on aws, there is no high load, there is an external ip listening to the WebSocket 443 port, and sometimes there are some unknown detection signals "SSTP_DUPLEX_POST" that will cause port 443 to fail to respond. Need to restart kamailio Then, it stopped responding again after about a month.

Failing Audio stream on Kamailio+webrtc with integration to asterisk server
by Kelvin Ezenwaka 16 May '22

16 May '22

Summary: We have a Kamailio server as our sip proxy server, sip firewall with WebSocket and RTP engine configured on it (the Kamailio Server). But we experience one way audio, no audio, hang up after 30s, when we try making calls between internal extensions (eg extension 100 to call extension 105) and external calls (eg extension 100 to call mobile number 09056925668) as well. The call flow is as: Webrtc client<------->Kamailio1+rtpengine<-----Asterisk---->Kamailio2<-------->Telco Provider The asterisk communication between all three boxes is via local IP (All ports open between them). The Kamailio 1 box where we have our sip registration cache, has rtp ports and wss port open on the internet. Asterisk 18.9.0 Kamailio 5.5.3 + RTPengine 10.4.0.0 Debian 11 bullseye Kindly see attached below a diagram depicting the VoIP network flow and also attached are logs files for the webrtc client and server side.

Question on pike_check_ip(ipaddr)
by Joel Serrano 13 May '22

13 May '22

Hello, One of our customers has lots of extensions that register to our platform using all the same IP. Sometimes they get caught in our pike velocity rules but if we increase the values to accommodate this client then all the others could abuse the system. I was wondering if pike_check_ip(ipaddr) needs strictly an IP as parameter or can it be a string? I was thinking of using pike instead of by $si by something like $fU-$si but I don't know if this would work? I need to either handle separately different extensions from the same IP or a way to adjust the pike config values just for one specific IP... I'm not sure either of these is possible with pike? My alternative is just use table and mimic the functionality myself which I don't think is too complicated, but I'd love to know if I'm missing a fast-path here... Thanks! Joel.

Info: converting dokuwiki content to markdown files
by Daniel-Constantin Mierla 12 May '22

12 May '22

Hello, it was discussed a couple of times during the past Kamailio development meetings and several days ago the works started to convert the Kamailio Wiki content to markdown format and host the files on Kamailio github.com organisation. The Dokuwiki engine has served us very well during more than a decade and a half, but open editing had to be disabled many years ago due to bad actors pushing inappropriate content. The contributors had to make a dedicated account on our portal only for Wiki editing. More recently we had add another layer of protection requiring to grant manually edit permissions to newly created wiki accounts because bots started to work around CAPTCHA and other security extensions, posting again inappropriate content. All these added to operational overhead, but also made it difficult for new people to contribute, specially for small editing to fix typos or add usage examples. Thanks to Kenneth Stowe, who undertook the first big effort of converting the Dowkuwiki files to markdown format, we are now in the position of moving further with the plans of using github for hosting the content of the wiki and enable easier contributions via pull requests. The history of changes done via Dokuwiki show up now as git commits. The github repository for the wiki content is available at: * https://github.com/kamailio/kamailio-wiki It is still work in progress, therefore we ask for the help of community to speed up the conversion, among the tasks that need to be done: * convert relative links between wiki pages – the conversion tools used relative paths without file extensions, like: [Install Kamailio v4.4.x From GIT](/install/4.4.x/git) They have to be converted to relative path with .md extension in order to be able to browse directly :n the github.com portal — practically the leading / has to be removed and .md added at the end, like: [Install Kamailio v4.4.x From GIT](install/4.4.x/git.md) * some section heading markers were not detected/converted, onee may notice many equal signs (=) around a section name, it has to be replaced with the appropriate markdown format based on hash signs (#). For example: ======= Install And Maintain Kamailio v4.4.x From GIT ======= Should be converted to: # Install And Maintain Kamailio v4.4.x From GIT * some Dokuwiki paragraphs used special formatting based on plugins, for example the notes, warnings, … had special colors. The common markdown format does not specify a syntax to color the text, the propose solution is to use emoji at the start of the paragraph to signal its special purpose. For example, the Dokuwiki content: <color blue>//IMPORTANT: Content for older releases than 3.2.0 is available at the **Old Wiki Site**://</color> Has to be transformed to: :fire:*IMPORTANT: Content for older releases than 3.2.0 is available at the **Old Wiki Site**:* You are welcome to propose a better syntax for this kind of transformation. * review config examples and evaluate what improvements can be done (e.g., in terms of formatting and syntax highlighting) Any of these changes do not require any C programming knowledge, nor much Kamailio config knowledge. Can be your first contribution to the project and it will be very appreciated. It can also help you learn more about Kamailio, because you may discover documentation that you were not aware of. A very important decision is how to present the wiki markdown content on kamailio.org website. Besides being able to see it on github repository, we want to process the markdown pages somehow and make them available in html format on kamailio.org website for easier navigation and better indexing (e.g., with tables of content for large pages). If you are aware of a suitable cli or web app that can convert markdown to html and generate table of content, let us know. Any questions and suggestions should be addressed to sr-users(a)lists.kamailio.org mailing list. Looking forward to your contributions on this community effort!

Using TLS in Kamailio behind AWS NLB
by Aditya Uppuluri 12 May '22

12 May '22

Hello Team, I want to understand if there is any recommendation on installing kamailio behind AWS NLB. I want to enable TLS at the NLB (using the certificate generated via Aws Certificate Manager) but still use the TLS module functionalities in kamailio (like listening on 443 port/updating the correct via header and all). Because NLB by default doesn't understand sips/TLS, I need a way to differentiate whether the request came on a secure line or on a plain UDP line. How do I configure this? Do I need to generate new certificates for kamailio ? Thanks in advance Regards, Aditya

Detect RTP stream end (Kamailio + rtpengine)
by Rawad Kassir 11 May '22

11 May '22

Hello, I am trying to play early media purely relaying on kamailio and i have accomplished that using the below: rtpengine_manage(); append_to_reply("Content-Type: application/sdp\r\n"); $var(body)= $(rb{re.subst,/(IP4.).*/\127.0.0.1/g}); set_reply_body($var(body), "application/sdp"); send_reply("100","Trying"); send_reply("183","Session In Progress"); play_media("totag=$ft file=/home/rawad/test.wav"); My problem is that once the RTP stream starts the call is kept open so my question is is there a way for kamailio to detect the end of rtp stream so that i can send BYE or can kamailio do that automatically.

Proxy for ACK
by Rick van Rein 09 May '22

09 May '22

Hello, RFC 3261 gives (by way of example) an ACK that is sent directly to a remote phone via its Contact: header address. Is this the _only_ way of doing this, or may ACK also be passed through a SIP proxy? I found that my Kamailio setup does not forward ACK, and I wonder why; whether that is a common refusal, or my fault in modifying the proxy script. I am working on an IPv4-only to IPv6-only translation proxy, and would like to leave the DNS-related work to a more advanced SIP proxy. The translator is supposed to be small/simple, so it can be integrated into home routers. I would like to avoid DNS resolution (and its delays) for Contact: URIs. Proxy script, https://gitlab.com/arpa2/mkroot/-/blob/master/contrib/sip-trunk/etc/kamaili… SIPproxy64 translator, https://gitlab.com/0cpm/sipproxy64 Thanks, -Rick

Hello guys, I'm trying to use: if(dns_query("$du", "xyz")) And all I get is dns_update_pv(): container not found: xyz Any ideas? I'm not really sure what that means. I know there's supposed to be a $dns(xyz) but it looks like it's not there? I'm using 5.0 BTW. Thanks all & Regards, David Villasmil email: david.villasmil.work(a)gmail.com phone: +34669448337

calling failure_route
by David Villasmil 06 May '22

06 May '22

Hello guys, Is it possible to call a failure_route like a normal route? i.e.: { t_on_failure("myroute"); } ... route("myroute"); failure_route[myroute] { ... } Let me explain: I have this scenario where a DNS name may get deleted and a dns resolution will fail. There's no pinging to that gateway so i need to: - skip that gateway when dispatching to the setid - detect whether the domain is up and available And failover to the next gateway. I don't know of any other way so on the DISPATCH route, I'm doing: route[DISPATCH] { # round robin dispatching on gateways group '1' if(!ds_select_dst("1", "4")) { send_reply("404", "No destination"); exit; } xlog("L_DBG", "--- SCRIPT: going to <$ru> via <$du>\n"); if(dns_query("$du", "xyz")) { t_on_failure("RTF_DISPATCH"); route(RELAY); } else { route(RTF_DISPATCH); } exit; } to try to resolve and if it fails, it will just go to the failover route. makes sense?

BYE is being sent using the Dialog ID (did)
by mack＠dopensource.com 06 May '22

06 May '22

I configured the dialog module to match routing based on SIP elements versus the (Dialog ID) did. It looks like it’s using the callid SIP element, but it’s still looking it up using the dialog module. I was hoping it would route on the RURI of the BYE. But, it looks like it’s using the dialog lookup table, which has the wrong RURI because that was the original server we sent the request to. How can I get Kamailio to route based on the RURI within the BYE.

Tips on picking random element from a list
by Joel Serrano 05 May '22

05 May '22

Hi Everyone, I have to implement a flow where outbound calls get their caller-id set with a random number from a pool. I've been looking around and, as most of the time, there are tons of ways to implement something like this... This is a simple implementation, the number pool is fixed and will not change (so I could have it hard-coded in the config if required). My initial approach was: 1- Try to keep it simple, with no dependencies, and all done in the config script. 2- If #1 is "ugly", then I'd probably go with some inline code using python/lua/etc 3- If #2 is "ugly", then I'd go with having the info in a DB and just run a query I think #2 and #3 might be overkill for something so "simple" but I haven't had to work too much with randomness in Kamailio, so any tips/suggestions on where to store the number list and how to pick one randomly would be awesome! Thanks!! Joel.

Development is open for future release of v5.7.x series
by Daniel-Constantin Mierla 05 May '22

05 May '22

Hello, the branch 5.6 was created, therefore the master branch is open for adding new features, to be part of future release series v5.7.x (or whatever version is decided for next series). Any bug fix committed to master that applies to 5.6.x or older stable branches should be backported as usual with "git cherry-pick -x ..." to appropriate branches like 5.6 or 5.5. Expect that v5.6.0 will be released in a few weeks from now. Based on the workflow used during the past years, the next future release v5.7.0 should be out after another 6-10 months of development, plus 1-2 months of testing, so sometime by end of 2022 or in the first part of 2023.

Development for v5.6.x is frozen
by Daniel-Constantin Mierla 05 May '22

05 May '22

Hello, the formal notification that the development for the next major version 5.6.0 is now frozen. The focus has to be on testing the master branch. Also, the master branch should not get commits with new features till the branch 5.6 is created, expected to happen in 2-4 weeks, a matter of how testing goes on. Meanwhile, the commits with new features in the C code can be pushed to personal branches, new pull requests can still be done, but they will be merged after branching 5.6. Can still be done commits with documentation improvements, enhancements to related tools (e.g., kamctl, kamcmd), merging exiting pull requests at this moment, exporting missing KEMI functions and completing the functionality of the new modules added for 5.6. Once the branch 5.6 is created, new features can be pushed again to master branch as usual. From that moment, the v5.6.0 should be out very soon, time used for further testing but also preparing the release of packages. If someone is not sure if a commit brings a new feature, just make a pull request and it can be discussed there on github portal or via sr-dev mailing list. A summary of what is new in upcoming 5.6 is going to be built at: * https://www.kamailio.org/wiki/features/new-in-5.6.x Upgrade guidelines will be collected at: * https://www.kamailio.org/wiki/install/upgrade/5.5.x-to-5.6.0 Everyone is more than welcome to contribute to the above wiki pages, especially to the upgrade guidelines, to help everyone else during the migration process from v5.5.x to 5.6.x.

sanity_reply not available from sanity module
by Patrick Karton 04 May '22

04 May '22

Hello , the sanity_reply function from sanity is not available in kamailio script so i get an error when i want to use it. in the module source i see this static cmd_export_t cmds[] = { {"sanity_check", (cmd_function)w_sanity_check, 0, 0, 0, REQUEST_ROUTE|ONREPLY_ROUTE}, {"sanity_check", (cmd_function)w_sanity_check, 1, fixup_igp_null, 0, REQUEST_ROUTE|ONREPLY_ROUTE}, {"sanity_check", (cmd_function)w_sanity_check, 2, fixup_igp_igp, 0, REQUEST_ROUTE|ONREPLY_ROUTE}, {"sanity_check", (cmd_function)w_sanity_reply, 0, 0, 0, REQUEST_ROUTE|ONREPLY_ROUTE}, {"bind_sanity", (cmd_function)bind_sanity, 0, 0, 0, 0 }, {0, 0, 0, 0, 0, 0} }; why is sanity_check linked again in w_sanity_reply ? is this an error ? i want to setup specific responses for some errors and let the default ones from module work as usual. Thanks.

Hello guys, I'm starting to try KEMI and i already hit a snag... right now i'm simply testing with: loadmodule "app_lua.so" modparam("app_lua", "load", "/etc/kamailio/myscript.lua") cfgengine "lua" route { lua_run("send_reply"); } But i'm always getting: 0(118) ERROR: app_lua [app_lua_api.c:1633]: sr_kemi_lua_modf(): function 'sl_send_reply' is not available I'm guessing that function is not exported by the module.. if that's the case, how can i use it?

Dispatcher SRV load balancing
by Nicolas Chapleau 03 May '22

03 May '22

Just having a hard time trying to see if the Dispatcher module does LB when SRV records are used as the destination. Will the destinations be picked based on the SRV list or will it simply use the first name received? Read lots of docs, but can't seem to figure it out Thanks, Nic.

Problem with Record-Route in Public to Private Network
by Carlos Escalona 03 May '22

03 May '22

Hello! I wish everyone who reads this message a good day. I would appreciate some guidance with the configuration of my Kamailio. Initially, I have the following architecture: Endpoints <----Public IP----> Kamailio (listen PrivateIP advertise PublicIP) <----Private IP----> Asterisk CONFIG: https://gist.github.com/Carlos-Escalona94/3a289af05b05c69ae563ab29c9ec4710 In general, calls initiated from outside the system work perfectly, but I have a problem with calls initiated from Asterisk. According to what I was able to investigate and understand, the problem arises from the fact that Kamailio uses the public IP for the entire routing system that involves the Record-Route and Route Headers. This in turn causes Asterisk to get lost trying to send messages outside of the INITIAL INVITE transaction, for example, the ACK response to the 200 Ok received from the Endpoint since it tries to use Kamailio's public IP to which Asterisk doesn't have access. I tried to force Asterisk to send all messages to Kamailio's private IP regardless of their nature, but it doesn't seem like an appropriate solution. On the other hand, I tried to modify the architecture a bit so that it was something similar to this: Endpoints <---- Public IP----> Kamailio (listen PrivateIP:P1 advertise PublicIP) <---- PrivateIP-----> Kamailio (listen PrivateIP:P2) <---- PrivateIP ----> Asterisk CONFIG: https://gist.github.com/Carlos-Escalona94/4d681bb189c6190941d291965e123889 It seems to me that this would solve the problem, but I have two doubts about this architecture, the first is that I would like to know if there is an easier way to solve the problem that I am not considering, and on the other hand, I have not found a way to identify from which interface is receiving the message to perform the routing properly.

Getting "uac.reg_add" to work (documentation unclarities)
by Rick van Rein 29 Apr '22

29 Apr '22

Hello, I am trying to make UAC register with a SIP telco. But when I run... shell$ kamctl rpc uac.reg_add mydomain.com 0123456789 myteldomain.com 0123456789 sip6.telco.nl telcoreseller.nl 999999 secretpw . udp:sip6.telco.nl 360 0 10 'udp:[fd8:9::10]:5090' ...it gives me the cryptic response... ERROR: jsonrpcs [jsonrpcs_mod.c:666]: jsonrpc_scan(): field is not a string - type 3 The module docs only give "..." as example of attributes. And, according to... http://www.kamailio.net/docs/modules/5.4.x/modules/uac.html#uac.r.uac.reg_a… https://github.com/kamailio/kamailio/blob/5.4.4/src/modules/uac/uac_reg.c#1… ...it also seems to be behind on diff_expires, timer_expires, reg_init. What I am missing is the format, and in some cases the purpose of attributes. Could you help me to an example, perhaps based on the command I am trying? Thanks, -Rick P.S. It's been years since I worked with OpenSIPS. It feels like Kamailio is friendlier, and easier to use.

Dispatcher Usage and change of $rU
by Benoît Panizzon 29 Apr '22

29 Apr '22

Hi Gang I have a observation which I don't understand... Let's assume we have an inbound $rU = 12345 And I want to change $rU outbound to 0012345 Doing: $rU = "0012345"; ds_select_dst("2000"),"6"); route(RELAY) The call is being sent out with unaltered R-URI Username: 12345 Doing: $rU = "0012345"; ds_select_domain("2000", "6"); route(RELAY); The call is being sent out with the intended new R-URI Username: 0012345 Looking at the docs: https://kamailio.org/docs/modules/5.4.x/modules/dispatcher.html#dispatcher.… I can not figure out, why I see this difference. -- Mit freundlichen Grüssen -Benoît Panizzon- @ HomeOffice und normal erreichbar -- I m p r o W a r e A G - Leiter Commerce Kunden ______________________________________________________ Zurlindenstrasse 29 Tel +41 61 826 93 00 CH-4133 Pratteln Fax +41 61 826 93 01 Schweiz Web http://www.imp.ch ______________________________________________________

Incorrect Socket and Tcpconn-Id with Mid-Registrar and WebSockets
by Grant Bagdasarian 29 Apr '22

29 Apr '22

Hi, We're attempting to implement a mid-registrar for websocket connections but are running into some issues where the tcpconn-id and socket attributes are not stored correctly in memory (usrloc). REGISTER Flow: UA1 -> P1 (Mid-Registrar) ~> P2 (Core Proxy/Registrar) INVITE Flow: UA2 -> P2 -> P1 -> UA1 UA1: baresip cli connecting to P1 using websockets UA2: softphone Everything is running locally on a dev machine, and we're using Docker to launch P1 and P2. The below code snippet is what we use on P1, and has been simplified. The general idea is as following: 1) UA1 sets up the websocket connection and sends a REGISTER request to P1 2) P1 checks if this request has already been sent to P2 2.a) If not, then relay the request to P2. Upon receiving a 200 OK from P2 we save the registration in usrloc 2.b) If so, then absorb the request (save) and generate a reply 3) UA2 tries to call UA1 via P1 and P2 The problem occurs at 2.a since the REGISTER request is forwarded using UDP and the 200 OK is also received using UDP. When the registration is stored in reply route, the Socket (udp:x.x.x.x:xxxx) and Tcpconn-Id (-1) are not set to what we would prefer (see Output 1) TCP was also tried as the transport between P1 and P2. Upon receiving the reply from P2 the Tcpconn-Id and Socket of the connection between P1 and P2 was saved in the binding. When 2.b occurs the Socket and Tcpconn-Id are set to the correct values (see Output 2) Making a call when the binding state is at 2.a we receive the following error: "TCP/TLS connection (id: 0) for WebSocket could not be found" Making a call when the binding state is at 2.b works perfectly fine since the correct Tcpconn-Id is set. We did find a solution, or rather a workaround to this issue: 1) Always call the save function in request_route 2) If P2 responds with an error (non-200 OK) use the unregister function to remove the binding We also tried the tcpops tcp_set_otcpid and tcp_set_otcpid_flag functions after lookup, but this didn't do anything.

TOPOS, 183 (before a 200OK) and SIP INFO
by Giovanni Tommasini 28 Apr '22

28 Apr '22

Hi kamailiers, I ask your help for a strange situation with topos, 183 (before a 200OK) and SIP INFO My topology is kamailio in front of asterisks; so kamailio has 2 interfaces (1Public to talk with customers and carriers and 1 Private to talk with asterisk). In the image: - the first column is the customer - the second is the public interface of kamailio - the third is the private interface of kamaiio - the fourth is asterisk As you can see in the image, the customer send an INVITE and the carrier give back the IVR messages in a 183 (before a 200OK) asking for an IVR selection. The customer (configured to use SIP INFO) types a key and sends in INFO, but as you can see kamailio sends the INFO to himself to private interface instead of sending it to asterisk as if the contact that handled topos contained incorrect information. [image: Schermata 2022-04-26 alle 19.40.32.png] - If the customer is configured with a RFC2833 - or if the IVR messages is not in a 183 but is sent after a 200OK - or if I disabe TOPOS *all works fine* I used kamailio 5.5.3, I also try to upgrade to 5.5.4 but nothing change Maybe could be connected with https://github.com/kamailio/kamailio/issues/2344 https://github.com/kamailio/kamailio/issues/1077 Could be a kamailio bug for this particular situation or am I getting lost in a glass of water? thanks a lot cheers Giovanni Tommasini *evoseed s.r.l.* phone: +39 340 11 28 800 mail: giovanni.tommasini(a)evoseed.io site: evoseed.io address: Via Lucrezio 13, Trieste Italy

Kamailio functionality clarification - call forwarding no replay (call is ringing but not answered)
by Pavel Veselovsky 28 Apr '22

28 Apr '22

Hallo all, I would need help with Kamailio. I hope, you can give me some hints. I would like use Kamailio for CFNRy feature call forward no replay, i.e. - call is forked to multiple destination - 180 is received, call is ringing, but not answered, no 200 OK is received from destinations - after predefined time (CFNRy timer), the specific branch has to be rerouted to another destination Expected behaviour is described in this flow: [image: image.png] My current behavior: - Kamailio TM module is involved for parallel forking ( https://www.kamailio.org/docs/modules/stable/modules/tm.html#:~:text=1.-,Ov… ) - all branches are CANCEL-ed, it is not possible send CANCEL just to one specific branch [image: image.png] My questions: - is it possible to CANCEL just specific branch of parallel forked calls? - is it possible start timer just for specific branch? - do you think is it possible implement this feature with Kamailio? Thanks a lot in advance for any comments. Pavel.

I am using Kamailio as registrar and proxy for underlying asterisk server. I am able to call but ACK on 200 OK respond from client phones are not validating transaction and thus not relaying correctly. Below are my Invites and 200 OK responses.

Modify session name in SDP
by ZZ Wave 28 Apr '22

28 Apr '22

Hello. Kamailio 5.2.1, Debian 10. I need to change session name (s=) in SDP before relaying it to next hop, and for unknown reason I can't do it with virtually any TEXTOPS function, everything replace*, subst*, *body*... For example this from TEXTOPS documentation: subst_body('/^s=(.*)/s=root/') just before 'final' t_relay(). Either Kamailio just adds "s=root" to SDP leaving first "s=" intact, or adds just "root", or does nothing. Also I've tried msg_apply_changes() before and after these manipulations, still no result. Is it possible to make this in Kamailio without source code modification?

High performance
by Muborakshohi Masoud 27 Apr '22

27 Apr '22

Hello! I have kamailio 5.5 configured with digest authentication. DB Mysql, 2 rtpengine one on the same server with kamailio, the other is separate. Rtpengins work in bridge mode, internal/external/external-ipV6. Kamailio listen 3 address: internal/external/external-ipV6 work in mixed mode: ipV4-ipV4, ipV4-ipV6, ipV6-ipV6. OS Debian 10, CPU 1 core, Ram 4gb, Disk not ssd. internal address is used for the gateway model of the connection to the PSTN. Before sending a call to PSTN, a request is sent to Billing by Diameter (request over the network, ims_charging ), Billing responds in the region of 10-17 milliseconds. usrloc db_mode = 0; UAS contacts are received according to the PUSH scheme (we send PUSH via http and get a REGISTER). children = 8 for each; When running synthetic tests with sipp, I get 36 cps as a maximum, but there are a lot of retrans. This is a test environment. Product: I plan to get 100 cps; 20k concurrent calls, hardware will be 128GB RAM ddr4-2400; Intel Xeon Silver 4216, Optane SSD. 2 such servers, kamailio/rtpengine are configured exactly according to the scheme of the test environment. Question: Can you please tell me how many children, shm/pv do I need? Is it worth going in the direction of asynchrony, or is the standard one enough for my purpose? I will be very glad for any help. Thank you! -- Отправлено из Mail.ru для Android

Hi, I'm trying to use LCR with kamailio v5.5.4 gw, rule and rule_target are stored on mysql. for lcr rules, do you know if prefix is mandatory ?

Local Registration Cache
by Linux Vince 26 Apr '22

26 Apr '22

Hello, I am trying to implement scenario described in this thread by Daniel-Constantin Mierla. I am able to cache registration using save but i am not able to handle unregistration. Unregister function of registrar module is not available in onreply routes and I cannot unregister until upstream registrar returns 200 OK on Expire 0 message. Is there any workaround to fix this? Thanks,

SSL errors with websocket clients
by Vinicius Kwiecien Ruoso 22 Apr '22

22 Apr '22

Hi all! How are you? I have a kamailio instance and some users are having issues connecting via websocket using TLS. The logs show SSLv3 errors. Cannot find why that error would show up if SSLv2/3 is not enabled. Double checked it via SSLLabs that only TLSv1.2 is allowed in the service. Error sample: ``` 15(36) ERROR: tls [tls_util.h:42]: tls_err_ret(): TLS accept:error:14094416:SSL routines:ssl3_read_bytes:sslv3 alert certificate unknown 15(36) ERROR: <core> [core/tcp_read.c:1512]: tcp_read_req(): ERROR: tcp_read_req: error reading - c: 0x7fafc8768190 r: 0x7fafc8768278 (-1) ``` This instance has close to 400 websocket connections opened during the day. I have a high log level enabled. I was not able to identify any reason why this happens. The certificate is a Letsencrypt certificate. The issue is that sometimes clients have a hard time connecting to the websocket and that maybe related. Below are a few more details about the config. Please let me know if you have any pointers on how to debug those connection issues. 8<----- TLS config: modparam("tls", "tls_method", "TLSv1.2+") modparam("tls", "verify_certificate", 0) modparam("tls", "require_certificate", 0) modparam("tls", "low_mem_threshold1", 0) modparam("tls", "low_mem_threshold2", 0) modparam("tls", "private_key", "/etc/certs/tls.key") modparam("tls", "certificate", "/etc/certs/tls.crt") version: kamailio 5.3.9 (x86_64/linux) 8<----- This is related to the issue https://github.com/kamailio/kamailio/issues/3085 (as pointed out it is not a problem in Kamailio code). Thanks, Vinicius

How to disable video in invite with both audio and video
by Simone de Blasiis 22 Apr '22

22 Apr '22

Hello to everyone, we have a Kamailio 5.5 + RTPEngine deployment. Some devices will send an invite with both audio and video in the offer and we are trying to disable the video portion of the invite by either setting the video port to 0 or by setting a=inactive in the video portion of the SDP packet. We know that sdpops has a function that would be able to remove the video portion but it violates standards so we can't use it. We need to disable the video in the SDP offers because one of the pstn providers we are using doesn't accept invites that contain a video offer. I've spent days searching but I can't find an obvious way of achieving this. We were originally doing it with textops but we've been having some issues where the sdp wouldn't be modified correctly in reinvites after the original call is in place so we're looking for alternatives. Can someone please help us? Thanks in advance Simone de Blasiis
