number based routing and NATed peers
by Kiss Zoltán 12 Sep '23

12 Sep '23

Hello, Im gathering ideas about routing based on caller number to multiple peers and -lets say- subscribers. As far as i know we can route the calls with LCR based on prefix or the whole number to the LCR gateways which are specified in the LCR module gateway table. This is working very well with public IP based "peers". We can route calls to these gateways. But what can we do if we have to route to a "peer" which is behind NAT. Basically they have to REGISTER as a subscriber, but we cannot add a subscriber to the LCR gateway table, beacuse LCR module needs a directly reachable IP address with a fixed port. Does anyone have any ideas on how to handle these mixed type peers? Or maybe we have to add the fixed IP peers which are not REGISTERing to the usrloc database somehow and then we can do a lookup location based on $rU. To make myself clear, it would be nice if we can handle those 2 types of our peers unifromly in terms of SIP routing, thats why im looking for a "unified" solution. Thanks for your suggestions. With kind regards, Zoltan

Skip/discard branch in branch route?
by Benoît Panizzon 11 Sep '23

11 Sep '23

Hi all Is there a way to skip a branch in branch route? Situation: Two registrar server with DMQ synced location database. CPE register via TCP or TLS. To properly work, message have to be sent over the existing TCP connection. Multiple CPE register to one AOR. CPE1 and CPE2 register to Registrar 1 CPE3 registers to Registrar 2 On Registrar 1 there is an established TCP connection to CPE1 and CPE2 but not to CPE3. Within the Branch Route to the CPE I can check if there is a TCP as the Branch Route is executed for every contact in that AOR: branch_route[BR_TO_CPE] { [...] $var(reg_contact_addr) = $(ulc(aor=>addr)[$T_branch_idx]{uri.host}); $var(socket) = $(ulc(aor=>socket)[$T_branch_idx]); if ($var(socket) == 0) { xlog("L_ERROR", "$cfg(route): No Socket for: $var(reg_contact_addr)"); } [...] } This log an error if the socket is not present on the local registrar. But is there a way to tell kamailio to skip/discard that contact? My intention is to parallel branch from the core to both registrars, that way all contacts would still get the call but via established TCP socket (and in case of UDP and NAT via correct know ip for ALG port-forwarding). -- 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 ______________________________________________________

Question about a Slow timer process.
by Володимир Іванець 07 Sep '23

07 Sep '23

Hello everyone! I'm running Kamailio 5.6.2 and having a potential problem on one of the systems. The Slow timer process slowly consumes more and more of its PKG memory. I did not allow it to use all memory by restartink Kamailio during afterhours so I'm not sure what the consequences might be. I'm suspecting that this could be caused by my configuration but not sure how exactly. Can anyone please tell me how the Slow timer process can be debugged? Is it possible to see what it is storing in the memory and what data is piling up? Thanks a lot! Regarts, Volodymyr Ivanets.

uac_replace_to() without RR params
by Duarte Rocha 07 Sep '23

07 Sep '23

Hello all, I'm currently working on a proxy where I need to change To and From headers in order to normalize the numbers to +E164. I would like to be able to restore using and $avp() or $dlg_var() and without writing parameters on the Record-Route headers. I've tried to use restore_mode in auto mode and restore_dlg parameter with value 1 but still got the parameters on the inserted Record-Route. I've tried manual mode and using the configured $avp() to restore, but the parameters still got written on the Request-URI. I thought of using restore_mode with value "none" saving original values in an $avvp() and doing the replace, however, uac_replace() on Request Route or branch routes. That way i can't replace the values of To and From in the replies. That being said, my questions are : - Is there a way to use manual or auto mode without writing info on the Record-Route and only using $avp() ? - Is there a way to make changes on the To and From header on replies? Thanks in advance, Best Regards, Duarte Rocha

Unnecessary/Invalid AVPs in CCR message over Ro Interface
by s.ghahremannejad＠gmail.com 06 Sep '23

06 Sep '23

**Issue Description** I'm encountering an issue with my Kamailio configuration related to the inclusion of the "Accounting-Record-Type" (480) and "Accounting-Record-Number" (485) AVPs in Credit-Control Request (CCR) messages sent from the S-CSCF to the OCS. **Issue Details** - **Problem**: The "Accounting-Record-Type" and "Accounting-Record-Number" AVPs are being added to CCR messages generated by my Kamailio instance. - **Expected Behavior**: According to modern Diameter and 3GPP standards (e.g., RFC 4006 and TS 32.299), these AVPs should not be included in CCR messages. **Configuration Details** - **Kamailio Version**: 5.3.0 - **SigScale OCS Version**: 3.2.9 Note that I have redacted some specific information for confidentiality reasons. The actual values are placed in my Kamailio main configuration file (`kamailio.cfg`) and Diameter-specific configuration files (where applicable).

Configuring package memory
by Ivan Ribakov 05 Sep '23

05 Sep '23

Is there any specific reason why shared memory can be configured via the config files ("shm_mem_size") AND CLI flags ("-m") but package memory can only be set via CLI flags ("-M")? Did no one ever came across the need to configure the package memory limit so far, or is there another way to achieve it without using the CLI flag? -- Ivan Ribakov Software Engineer www.zaleos.net

Re: Kamailio stops processing UDP on one interface

Bastian, According to mine stats all seems ok... # kamctl stats shmem { "jsonrpc": "2.0", "result": [ "shmem:fragments = 330", "shmem:free_size = 1889418024", "shmem:max_used_size = 258962624", "shmem:real_used_size = 258065624", "shmem:total_size = 2147483648", "shmem:used_size = 248809096" ], "id": 212042 } pkg.stats also not showing any signs of exhausting.

Kamailio stops processing UDP on one interface
by Ihor Olkhovskyi 30 Aug '23

30 Aug '23

Hello, I've faced a bit strange issue, but a bit of preface. I have Kamailio as a proxy (TLS/WS <-> UDP) and second Kamailio as a presence server. At some point presence server accepts around 5K PUBLISH within 1 minute and sending around the same amount of NOTIFY to proxy Kamailio. Proxy is "transforming" protocol to TLS, but at sime point I'm starting to get these type of errors tm [../../core/forward.h:292]: msg_send_buffer(): tcp_send failed tm [t_fwd.c:1588]: t_send_branch(): sending request on branch 0 failed <script>: [RELAY] Relay to <sip:X.X.X.X:51571;transport=tls> failed! tm [../../core/forward.h:292]: msg_send_buffer(): tcp_send failed tm [t_fwd.c:1588]: t_send_branch(): sending request on branch 0 failed Some of those messages are 100% valid as client can go away or so. Some are not, cause I'm sure client is alive and connected. But the problem comes later. At some moment proxy Kamailio just stops accept UDP traffic on this interface (where it also accepts all NOTIFY's), at the start of the "stopping accepting" Kamailio sends OPTIONS via DISPATCHER but not able to receive 200 OK. Over TLS on the same interface all is ok. On other (loopback) interface UDP is being processed fine, so I don't suspert some limit on open files here. Only restart of Kamailio proxy process helps in this case. I've tuned net.core.rmem_max and net.core.rmem_default to 25 Mb, so in theory buffer should not be the case. Is there some internal "interface buffer" in Kamailio that is not freed upon failure send or maybe I've missed somethig?

How to forward 480
by Anthony Blandin 29 Aug '23

29 Aug '23

Hello, I have a Kamailio SBC connected to another foreign SBC and to a media server. In case of non response, Kamailio SBC receives a 480 Temporarily not available from the foreign SBC and I need to forward this 480 to my media server but I don't see how to do that. The 480 arrives in the onreply_route. If I use then a failure_route, it resends the initial INVITE and not the 480. Is there a way to do that? Thanks for your help. Anthony Blandin

Or, if you are good at Google search, I believe you can definitely find more ways to play the big dildo. All in all, huge dildos are the best sex toy for singles. For single women, it’s vaginal masturbation. For single men, it’s anal sex. https://www.hugedildo.com/

hi, i have open around ~8000 rtp ports for around ~200calls (in peak) with this statistic (current data, not from peak) rtpengine_closed_sessions_total{reason="rejected"} 0 rtpengine_closed_sessions_total{reason="timeout"} 237405 rtpengine_closed_sessions_total{reason="silent_timeout"} 103 rtpengine_closed_sessions_total{reason="final_timeout"} 0 rtpengine_closed_sessions_total{reason="offer_timeout"} 0 rtpengine_closed_sessions_total{reason="terminated"} 0 rtpengine_request_seconds_total{proxy="127.0.0.1",request="offer"} 539.270967 rtpengine_request_seconds_total{proxy="127.0.0.1",request="answer"} 367.237641 rtpengine_request_seconds_total{proxy="127.0.0.1",request="delete"} 0.000000 is it normal? (large number of timeouts, "zero" terminated) or i have missing rtpengine_manage (rtpengine_delete) somewhere? (os rocky 9.2, kamailio 5.6.4, rtpengine 11.3.1) thanks Marek

excessive CANCELs
by James Lipski 23 Aug '23

23 Aug '23

Hello, I've already suppressed this via routing logic, however I was wondering if there is a dedicated parameter that handles this. I'm currently running version 5.6.4. Scenario: UA-1 registered towards kamailio, calls UA-2 which is registered towards a different platform (non kamailio); so there are 2 proxys involved. kamailio is set to fork the call to voicemail if there is either no response completely from the other end, or the call goes unanswered. So the initial leg is: UA-1 <-----> kamailio <-----> second proxy <-----> UA-2 Issue: I'm trying to catch a case where the second proxy does issue a "100 Trying" for the initial INVITE; and then timesout. The call does fork to voicemail; however 14000+ SIP packets are generated between kamailio and the second proxy of CANCEL and "100 Trying" (the 100 Trying has a CSeq for INVITE still). Is there a way to suppress the amount of CANCELs that is transmitted in this situation? I'm using the following as my "tm" parameters: modparam("tm", "failure_reply_mode", 3) modparam("tm", "fr_timer", 30000) modparam("tm", "fr_inv_timer", 300000) modparam("tm", "auto_inv_100_reason", "Trying") Thanks.

Kamailio behind TLS-TCP load balancer
by David Villasmil 17 Aug '23

17 Aug '23

Hello all, I’m having lots of problems when trying to configure Kamailio behind an AWS tls load balancer to offload tls and receive on tcp on Kamailio. Everything else inside is UDP. I found I need to manually add record-route presets every time and invite comes in. And when trying to forward an ACK to the client via tls/tcp load balancer Kamailio complaint the socket is not TLS so it fails. Is there a simpler way of doing this via some parameters I don’t know? Thanks for helping me with this! David -- Regards, David Villasmil email: david.villasmil.work(a)gmail.com phone: +34669448337

Kamailio dns-failover / dns-loadbalancing with slow responding client.
by Mattis Lind 14 Aug '23

14 Aug '23

Hello! I am looking into a problem where we have Kamailio forwarding calls to two or more "recording-clients". I will try my best to describe the problem and would appreciate it if someone has an idea what to do. Please feel free to ask if you think I have forgotten to describe something that might be important or something is unclear in what I have written. We use use_dns_failover=yes and dns_srv_lb=yes so calls get load balancing to the "recording-clients". There is also the t_set_fr(60000,1000) parameter set so that if there is no response within 1 second it would try the next recording-client. The SRV record points to two or more recording clients. It now happens that the recording-clients sometimes have some kind of temporary problem so it will respond with a 503 after 5 seconds. What happens is that after the 1 second timeout trying to get the INVITE through to the first recording-client Kamailio will internally generate a 408. This will cause it to failover to another recording-client which happily takes care of the INVITE and responds properly with a 200 OK. Everything would have been just fine except for the fact that the first recording-client is just slow and finally responds with a 503. This 503 is not relayed backwards since a 200 has already been forwarded back to the caller. But when receiving the 503 Kamailio will initiate a new INVITE which is trying to set up a new call to a recording client. It looks like it is doing a new failover regardless if it already has done a failover for this failed transaction. I don't want Kamailio to send that last INVITE when receiving the 503. How can I configure Kamailio to disregard the last 503 (except for responding with an ACK) and not initiate a new INVITE? I have tried a lot of different changes to the configuration but failed to achieve this, unfortunately. Do I need to use the dispatcher module to achieve this? /Mattis

Modify To URI in Multiple Choices
by Ali Taher 11 Aug '23

11 Aug '23

Hello, I'm using Kamailio as SIP redirect where SBC sends INVITE packet to kamailio and "302","Multiple Choices" is sent back to SBC. What I want is to modify the URI part in the To header of the Multiple Choices packet sent from kamailio. I tried to use uac_replace_to("","sip:$var(cdpn)@$td") where $var(cdpn) is already defined in the routing logic, but it's not reflected and the original TO URI is sent instead. Any help to handle this issue is much appreciated. Regards,

how to get value of next hop
by Sergey Safarov 10 Aug '23

10 Aug '23

I receiving INVITE with two Route header (no to tag). First Route header is my Kamailio host. Second Route header is next hop after Kamailio. I need to get value of next hop. I tried to use "$route_uri" after "loose_route" but his deos works. "$route_uri" always use top Route header. But in the INVITE first Route header is Kamailio host. Is any change to get top Route header after "loose_route"?

Kamailio-asterisk BYE
by Dr. Barabás Péter 09 Aug '23

09 Aug '23

Hello, we work on a mobile softphone which connects to asterisk through kamailio. Almost everything is fine except one thing. Asterisk allows only one registration to an AOR. In mobile environment network can change, register/unregister can be called frequently in foreground/background cases. Kamailio forwards every request to asterisk. Until I have only one connection between kamailio – asterisk, everything is fine. The next situation is problematic: 1. Client A and client B register to asterisk through kamailio. –> there will be one connection between kamailio and asterisk 2. Client A calls client B. • one connection exist still 3. If client A terminates the call -> one connection remains. It is okay. 4. If client B terminates the call -> a new connection appears (kamailio IP with new port) After case 4 If I try to register again, I got 403 from asterisk, since the setting of asterisk does not allowed to register from different IP:port for the same AOR. (this behaviour cannot be changed now). The question: is there any setting/config exist in kamailio not to create new connection for a BYE in above case. Thanks in advance for your reply. Peter

Htable question
by Stefan-Cristian Mititelu 09 Aug '23

09 Aug '23

Hello, Can one kama process iterate a htable using sht_iterator_start(), sht_iterator_next(), sht_iterator_rm(), sht_iterator_end() while some other kama process call sht_rm(htable, item) ? I've looked into code and to me it looks like slots are locked ok. The entire linked list(specific to a slot) where the item might be, is locked, so this means there should be no problems, right? Thank you, Stefan

Problem connecting to Redis DB using DB_REDIS module with a Password
by Nick Digalakis 08 Aug '23

08 Aug '23

Hello everyone! I had a Kamailio 5.6.4 server using the DB_REDIS module for quite some time without a password on the Redis DB working just fine. A few days ago I decided to add a password to Redis and modify the Kamailio config file with the following line per the documentation to be able to authenticate: modparam("db_redis", "db_pass", "r3d1sPass") Since that moment, I see the following errors in the Kamailio logs: ...... kamailio: ERROR: <core> [core/modparam.c:175]: set_mod_param_regex(): parameter <db_pass> of type <1:string> not found in module <db_redis> kamailio: CRITICAL: <core> [core/cfg.y:3790]: yyerror_at(): parse error in config file /etc/kamailio/kamailio.cfg, line 556, column 49: Can't set module parameter ...... The documentation I am reading is here: https://www.kamailio.org/docs/modules/devel/modules/db_redis.html#db_redis.… Could someone help me figure out what I am doing wrong? Many thanks, Nick

Subscribers and peers handling
by Kiss Zoltán 08 Aug '23

08 Aug '23

Hello, We are trying to build a lightweight SBC solution for some external peers, but currently there is a mixed environment which is handled by Asterisk. We have some "peers" with IP based auth, and also some "subscribers" with register. We have succeded with the subscribers, because we can handle the numbers for those type of users with aliases in Kamailio. So basically we have a subscriber, lets call it "test", and we can add aliases for the subscriber like "3612345678@localhost", then if we are calling the number the routing goes to the contact of "test" subscriber. Currently the problem is that we dont have any idea about the IP based peers, because those peers not registering, so we cannot create aliases for them as far as i know. How do you solve this type of problem? Maybe im overcomplicating the situation, but i havent got any solutions in my mind currently. Thanks for your help and ideas. With kind regards, Zoltan

Connection to AWS services (e.g DynamoDB)
by Lewis Hutchinson 07 Aug '23

07 Aug '23

Hi Jakub Although no direct experience with this exactly as you have described I have used HTTP API out of Kamailio quite a bit and into other services. Which yes some ultimatly end in AWS> Having done our's in KEMI there is some difference however from our experience we did notice some of this didn't fair well under a loads test scenario. We tested Kafka vs Kamailio HTTP API Modules vs Aiohttp (Python in Kemi) and Kafka significantly out perfomed in terms of the load test. We then had to rejig things to account for this instead of HTTP API. If this is ever going to be under intense load. Maybe make sure you do the load testing early on before you ratify your design. Also make sure all your error habndling is in place and working to prevent issues in Kamailio if something API side goes wrong. Mission Labs Limited is registered in England, company number 10040088.

Connection to AWS services (e.g DynamoDB)
by jakub.smadis＠cloudtalk.io 04 Aug '23

04 Aug '23

Hello, I am researching how I could communicate from Kamailio (which runs on an AWS EC2 instance) with AWS services (e.g. DynamoDB) using HTTP API. My Kamailio logic is written in Kamailio configuration files. I would like to ask you if anyone has some experience with such a setup and if so how did you manage to connect it? My current options are: * HTTP connection to DynamoDB API with HTTP module I would create a Python script that would generate signature headers for the [AWS API request](https://docs.aws.amazon.com/IAM/latest/UserGuide/create-signed-req…. Then I would use the headers in the HTTP request. (I am using the Kamailio module to keep the connection open to DynamoDB). * Middleman service Small service that provides HTTP API to Kamailio and manages the communication with DynamoDB. Easiest solution but it's harder to maintain it in high availability mode. * API gateway with VPC endpoint attached to the EC2 API gateway would be a proxy to DynamoDB and we would call the VPC endpoint from the Kamailio. We would use resource policies to allow requests without auth through the VPC endpoint. Any help or feedback would be valuable to me. Thank you very much! Regards, Jakub
