Kamailio with Asterisk as Media Relay
by Benjamin Marty 08 Oct '18

08 Oct '18

Hello I would like to ask if there is any available informations on how to use Kamailio as a SIP Proxy but letting (multiple) Asterisk Instances do the Media Relaying. Is this scenario supported and if yes are there any tutorials or documentation available for it? I know the Kamailio Dispatcher Module, but this does as far as I know a dispatching of also the SIP Traffic. Not just the Media Traffic.

set_advertised_address with variable
by Patrick Wakano 08 Oct '18

08 Oct '18

Hello list, Hope you all doing fine! I am using version 5.0.7 and I was trying to use the set_advertised_address with an avp variable but it does not replace with the avp value.... I then find out this thread https://lists.kamailio.org/pipermail/sr-users/2016-March/092327.html, in which is mentioned: *"I expect those functions not to support pvs, but I think this issomething to address in 5.0 and get all core functions working with pvs."* Looks like this was actually not done.... is that correct? Is there any plan to do it? In my case I want to use the set_advertised_address after reading the value from DB, so I can't use the advertised_address or listen options.... Any idea on how I could achieve that? Thank you, Kind regards, Patrick Wakano

Sending INVITE from loopback subnet
by Joonas Kamailio 08 Oct '18

08 Oct '18

Dear List, I am trying to achieve a scenario where I can recognize the original peer and mask it as peer from subnet 10.0.7.0/24 with kamailio. Basic IP connectivity is established with the following network configuration (Debian9): auto lo:1 iface lo:1 inet static address 10.0.0.0/24 And of course I have routed 10.0.0.0/24 to servers public IP address (hereby known as x.x.x.1) in my router. Please consider the following scenario: - Peer1 192.168.0.1 is sending INVITE to kamailio at IP x.x.x.1 - Kamailio sends INVITE to peer2 at 172.10.0.1 from socket 10.0.0.1 - Peer2 receives the INVITE and knows that since it came from IP 10.0.0.1 it means that INVITE is originally from peer1 - IF peer2 sends INVITE to kamailio, it should be sent to peerX from socket 10.0.0.2 This works if I list both 10.0.0.1 and 10.0.0.2 with 'listen=' parameter but things get out of hand if I have multiple peers. In my tests I have noticed that 60 peers equals 60 listen parameters which equals roughly 500 kamailio processes. At some point there are just too many processes and everything melts. If I omit the listen parameter altogether, kamailio has only one socket from /24 subnet and it is 10.0.0.0. Error message when listen parameter is omitted: [pv_core.c:2612]: pv_set_force_sock(): no socket found to match [10.0.0.1] My kamailio has the following configuration in request_route: $avp(e_private) = $(sht(get_private=>$si)); $fs = $avp(e_private); I know that the case is a bit confusing and totally something normal people won't do. If you have any questions I am happy to answer. Best Regards, Joonas Keskitalo

Server_id expects number only
by Denys Pozniak 08 Oct '18

08 Oct '18

Hello! I need to separate Kamailio's dmq_usrloc by server_id and will be much easily if server_id can accept string values also, like: server_id="192.168.100.100" But currently it accepts only integer: https://www.kamailio.org/wiki/cookbooks/5.1.x/core#server_id Syslog: 0(11488) CRITICAL: <core> [core/cfg.y:3447]: yyerror_at(): parse error in config file /etc/kamailio/global.cfg, line 126, column 11-24: syntax error 0(11488) CRITICAL: <core> [core/cfg.y:3447]: yyerror_at(): parse error in config file /etc/kamailio/global.cfg, line 126, column 11-24: number expected -- BR, Denys Pozniak

High number of aborted mysql connections
by Sergiu Pojoga 08 Oct '18

08 Oct '18

Hi all, I'm trying to understand why some Kamailio processes become Connor MacLeod and go to live forever causing high # of aborted connections. While watching in time over *SHOW PROCESSLIST*, some 12 kamailio connections in *SLEEP* state, most of them are reused over time (time value gets reset). However, a select few go on to SLEEP forever for as much as the mysql's *wait_timeout* allows them to. Default was 28800 sec, that's how long they lived. If I lower this to say 600 sec, even higher abort rate is observed. I suppose my questions are: 1. Is this normal to have so many SLEEPing connections? 2. What is the recommended MySQL *wait_timeout* value under Kamailio? 3. Any other suggestions as to why such a high rate of aborted connections? Merci!

Intercepting local reply attributes
by Alex Balashov 06 Oct '18

06 Oct '18

Hi, I have Kamailio in a weird interop/adaptation layer role with the following call flow: SUBSCRIBE to Kamailio with Expires: 0 ---> <-- immediate 200 OK from Kamailio [some time passes] <-- NOTIFY with additional info from Kamailio 200 OK to Kamailio ---> The NOTIFY follows a series of lengthy async HTTP interrogations, so it's constructed at a later point in time with $uac_req(...). The problem is that the standard which regulates this is extremely eccentric in the following way: despite the immediate expiration of the subscription, the NOTIFY is expected to conform to the format of an in-dialog request as if a dialog existed. Don't ask. It's as idiotic as it sounds. But it's a Broadsoft "standard". I can match the To URI / To-tag by capturing it from the incoming From header on the SUBSCRIBE and reproducing it into the outgoing To header on the NOTIFY. The issue is that my From-tag on the NOTIFY does not match the To-tag on the 200 OK for the SUBSCRIBE. So, from the point of view of the subscriber, the NOTIFY is "From" a different party to the one that "initiated" a "dialog" in response to its subscription. I'm just sending the "200 OK" for the SUBSCRIBE like this: --- append_to_reply("Event: $hdr(Event)\r\n"); append_to_reply("Expires: $hdr(Expires)\r\n"); append_to_reply("Contact: <sip:$sel(cfg_get.domain.sip_domain):$Rp>\r\n"); send_reply("200", "OK"); --- I am not aware of anything like an onsend_route that I can use to gain access to the To header of this reply. Nor am I aware of any means of removing headers from a reply and injecting my own To header with a self-generated To-tag I can later mimic in the From tag of the NOTIFY. Any creative workarounds would be appreciated! -- Alex -- Alex Balashov | Principal | Evariste Systems LLC Tel: +1-706-510-6800 / +1-800-250-5920 (toll-free) Web: http://www.evaristesys.com/, http://www.csrpswitch.com/

kamailio + rtpproxy behind NAT
by Bonjour Madame 05 Oct '18

05 Oct '18

Hello, I have kamailio and rtpproxy running on the same server located behind a router with NAT just like below. UA(internet)---public ip---router(NAT)--Kamailio+RTPproxy(private ip)--UA(private network) There are several issues like one way audio. I need users on the internet to communicate with each other, users on the private network to communicate with each other, and users on the internet and the private network to communicate with each other. What is the best approach? Best regards, Clarence

SIP communication does not reach phone when STUN is used
by Kevin Olbrich 05 Oct '18

05 Oct '18

Hi! I noticed a minor problem when I set up the STUN config of my phone. When the server is set, I am unable to reach the endpoint from kamailio (Phone1 -> Kamailio -> Asterisk -> same Kamilio -> no outgoing SIP flow to Phone2). If I do not set it, it seems to fallback to it's RFC1918 address which is then detected by nat_uac_test() and I can reach the phone. During my tests with Asterisk directly, this did not make any difference. Seems like Asterisk checks more than FLAG 19/8 in nat_uac_test(). If I am right, I strictly used the SIP source port for answers instead of any self-detection using STUN or similar. My kamailio node is connected to the internet directly and 95 percent of (planned) phones are behind random NATs. In example kamailio.cfg there are these settings: # Caller NAT detection > route[NATDETECT] { > #!ifdef WITH_NAT > force_rport(); > if (nat_uac_test("19")) { > if (is_method("REGISTER")) { > fix_nated_register(); > } else { > if(is_first_hop()) { > set_contact_alias(); > } > } > setflag(FLT_NATS); > } > #!endif > return; > } AND (modified for direct RTP flow): # RTPProxy control and signaling updates for NAT traversal > route[NATMANAGE] { > #!ifdef WITH_NAT > if (is_request()) { > if(has_totag()) { > if(check_route_param("nat=yes")) { > setbflag(FLB_NATB); > } > } > } > if (!(isflagset(FLT_NATS) || isbflagset(FLB_NATB))) return; > if(nat_uac_test("8")) { > fix_nated_sdp("15"); > if (is_request()) { > if (!has_totag()) { > if(t_is_branch_route()) { > add_rr_param(";nat=yes"); > } > } > } > if (is_reply()) { > if(isbflagset(FLB_NATB)) { > if(is_first_hop()) > set_contact_alias(); > } > } > #!endif > return; > } I checked the docs but I am not sure which FLAGs are safe to use (or break things). Any thoughts or hints are welcome. Thank you very much! Kind regards Kevin

Re: [SR-Users] Kamailio as TCP UDP proxy
by M K 05 Oct '18

05 Oct '18

Thanks, that was very helpful. But now I get an "ERROR: <core> [tcp_main.c:4070]: handle_tcpconn_ev(): connect <Client IP>:<Port> failed" displayed when trying to register. The SIP client establishes the connection to the proxy via TCP, but does not receive an answer. Could this indicate a faulty NAT-ALG?

Kamailio as TCP UDP proxy
by M K 05 Oct '18

05 Oct '18

Hi, I'm struggling with the configuration to use Kamailio as TCP UDP proxy: [SIP Client] <-(TCP)-> [Proxy] <-(UDP)-> [SIP Server] should be the setup. I only have one client and one SIP server. How do I get Kamailio configured as a proxy so that translation between TCP and UDP works (and vice versa)? I have not yet found any documentation and examples that have caused messages to arrive at my SIP server. I think I've been on the wrong track so far and I'm looking forward to any help. Thank you in advance, Laqoore

Development for Kamailio v5.2 series is frozen
by Daniel-Constantin Mierla 05 Oct '18

05 Oct '18

Hello, short note to mark the freezing of development for Kamailio v5.2 series. For few weeks, please do not push new features in the master branch. Once the branch 5.2 is created (expected to happen in 3-4 weeks from now), the master branch becomes again open for new feature. Meanwhile the focus has to be on testing current code. Work on related tools (e.g., kamctl) or documentation can still be done as well as getting the new modules in 5.2 in good shape, plus adding exports to kemi interface (which should not interfere with old code). The entire testing phase is expected to be 4 to 6 weeks, then the release of v5.2.0 will be out.

PATH when used with multiple listening ports
by Sergiu Pojoga 04 Oct '18

04 Oct '18

Hi again, When acting as an intermediary proxy for a non-colocated Registrar, the REGISTER request coming in on one port and going out on another, shouldn't the *add_path[received]()* generate *two* nodes in the Path header? Otherwise, how are the subsequent requests supposed to be routed back to the UAC? Scenario with Kamailio proxy on IP 1.1.1.1 with dual port listeners UAC => proxy:5070 <=> proxy:5060 => Registrar:5060 Path: <sip:1.1.1.1;lr;received=sip:123.123.123.123:59593> I would expect it to be something like: Path: <sip:1.1.1.1;lr>,<sip:1.1.1.1:5070;lr;received=sip: 123.123.123.123:59593> modparam("rr", "enable_double_rr", 1) modparam("path", "use_received", 1) Merci!

Using "Kamailio in a mobile world" as a base, I have the following routes to store information about the current transaction, however, if the transaction is already cancelled registrations for the user will still trigger `ts_append`, raising an error as the htable hasn't expired yet. Is there anyway to remove the htable entry when the original transaction cancels? Or something else that I'm missing?

Roadmap to next major release - v5.2.0
by Daniel-Constantin Mierla 04 Oct '18

04 Oct '18

Hello, as it was discussed during our last IRC devel meeting before the summer, the time to release a new major version should be this autumn. With the Kamailio Developers Meeting planned for September 27-28, 2018, I think it is better to freeze the code couple of days after that event. So I propose the following milestones: * on Thursday, October 4, 2018 - last development day, code for 5.2.0 will be frozen at the end of the day * 4 to 6 weeks of testing * release sometime in November, to be decided more precisely after the first weeks of testing, some rough candidates being within the weeks of Nov 5 or Nov 19 If anyone has something to add or adjust, let's discuss on sr-users mailing list.

Planing the release of Kamailio v5.1.6
by Daniel-Constantin Mierla 04 Oct '18

04 Oct '18

Hello, a matter of the schedule to be agreed in the morning and the availability during the Kamailio Developers Meeting, we may do a new stable release from branch 5.1.6 on Thursday, Sep 27, 2018, in the afternoon. Given that several of us will be in the same room, the special goal would be to try to automate the process as much as possible. If the time doesn't allow it, then the release will be done next week, a specific day to be decided by the end of this week. Anyhow, this is the informal notification to report as soon as possible any issues you are aware of and not yet in bug tracker, so they get a chance to be fixed.

is_first_hop() fails to detect 'myself' when using advertise
by Sergiu Pojoga 04 Oct '18

Hi ppl, If I add a FQDN advertise address to the listen statement, *is_first_hop() <https://kamailio.org/docs/modules/4.3.x/modules/siputils.html#siputils.f.is…>* seems to return FALSE no matter how I play with the listen and alias settings. listen=udp:1.1.1.1:5060 advertise sip.mydomain.net:5060 alias="sip.mydomain.net:5060" This statement doesn't get executed in the *onreply_route* *onreply_route[MANAGE_REPLY] {* *if(is_first_hop())* *set_contact_alias(); # contact alias doesn't get set?* *}* *is_first_hop()* *"The function returns true if the proxy is first hop after the original sender.

What is the typical network setup for kamailio?
by Kevin Olbrich 03 Oct '18

03 Oct '18

Hi! I am working successfully with Kamailio in my lab setup where Kamailio is the SBC for Asterisk. The network layout is looking like this: SIP-Phone <== PUBLIC NET ==> Kamailio (SBC) <== PRIVATE NET ==> Asterisk <== PUBLIC NET ==> Carrier Each public network is reachable from the internet and has a local firewall with IP whitelists. The internal SIP transactions are UDP-only but for external phones I would like to also listen for TCP/TLS. For this layout to work with rtpproxy (before we move on to RTPengine), we have to enable mhomed in Kamailio. We also have some routing issues with packets leaving with the wrong IP via rtpproxy (when call between carrier and external phone needs to be bridged). Most examples show that Asterisk is deployed on the same network as the external interface of Kamailio (-> Asterisk exposed to the public network). In our tests, this works much better but I have great security concerns because this Asterisk instance itself does not need to be reachable from external. How do other users deploy Kamailio in front of Asterisk or similar as SBC to secure internals? There is lot of docs for Kamailio's config but IMHO less for the setup as DMZ (SBC) proxy. Thank you very much. Kind regards Kevin

Using TLS on a load-balancing cluster behind DNS-SRV
by Kevin Olbrich 03 Oct '18

03 Oct '18

Hi! Which hostname do I need to request for the certificate when the servers are load-balanced using DNS-SRV? Do I need to get the cert for the DNS-SRV subdomain (without _sip._tls) or for the servers, eg. server0{1,2,3}.pbx.example.com ? Thank you! Kevin

rr module not detecting nat=ws route param
by Jon Bonilla (Manwe) 02 Oct '18

Hi all. I'm having problems with an indialog ACK request which is not being routed correctly. I call loose_route and print: $du=sip:MYIP:2443;transport=ws;r2=on;lr=on;did=1d1.7702;nat=ws $route_uri=sip:MYIP;r2=on;lr=on;did=1d1.7702;nat=ws But when I call check_route_param("nat=ws") I get false result. version: kamailio 5.1.4 any hints? cheers, Jon -- https://pekepbx.com https://www.issabel.com/multitenant

Dialog lifetime for dialogs synced with DMQ
by jenus＠cyberchaos.nl 02 Oct '18

02 Oct '18

Hello, I'm using DMQ to sync dialogs between a active and standby kamailio node. I noticed that when the standby takes over dialog's they do not expire after the lifetime i set on the other node. Is there a way to make sure that calls are terminated after the dialog lifetime expires? I see that the timer is replicated to the other node, but nothing happens after the dialog expires. The event routes aren't executed as well. Thanks, Jan

Fwd: kamailio with evapi crashing on high volume
by Jayesh Nambiar 02 Oct '18

Hello Daniel, Just a quick update on this. After running from the 5.1 branch twice it happened that Server became unresponsive. It never crashed and on forceful shutdown it only generated a core with shutdown routine. Here is what the syslog contained off while the calls were being sent to kamailio but kamailio was not processing any calls: Sep 22 16:09:04 triviamedia /usr/local/kamailio/sbin/kamailio[16006]: CRITICAL: <core> [core/mem/q_malloc.c:502]: qm_free(): BUG: freeing already freed pointer (0x7fcd23ce5648), called from tm: h_table.c: free_cell_helper(235), first free tm: h_table.c: free_cell_helper(235) - aborting Sep 22 16:09:04 triviamedia /usr/local/kamailio/sbin/kamailio[16006]: CRITICAL: <core> [core/mem/q_malloc.c:502]: qm_free(): BUG: freeing already freed pointer (0x7fcd24a38ea8), called from tm: h_table.c: free_cell_helper(234), first free tm: h_table.c: free_cell_helper(234) - aborting Sep 22 16:09:04 triviamedia /usr/local/kamailio/sbin/kamailio[16006]: CRITICAL: <core> [core/mem/q_malloc.c:502]: qm_free(): BUG: freeing already freed pointer (0x7fcd23ce5648), called from tm: h_table.c: free_cell_helper(235), first free tm: h_table.c: free_cell_helper(235) - aborting Sep 22 16:09:04 triviamedia /usr/local/kamailio/sbin/kamailio[16006]: CRITICAL: <core> [core/mem/q_malloc.c:502]: qm_free(): BUG: freeing already freed pointer (0x7fcd24a38ea8), called from tm: h_table.c: free_cell_helper(234), first free tm: h_table.c: free_cell_helper(234) - aborting Sep 22 16:09:04 triviamedia /usr/local/kamailio/sbin/kamailio[16006]: CRITICAL: <core> [core/mem/q_malloc.c:502]: qm_free(): BUG: freeing already freed pointer (0x7fcd23ce5648), called from tm: h_table.c: free_cell_helper(235), first free tm: h_table.c: free_cell_helper(235) - aborting Sep 22 16:09:04 triviamedia /usr/local/kamailio/sbin/kamailio[16006]: CRITICAL: <core> [core/mem/q_malloc.c:502]: qm_free(): BUG: freeing already freed pointer (0x7fcd24a38ea8), called from tm: h_table.c: free_cell_helper(234), first free tm: h_table.c: free_cell_helper(234) - aborting Sep 22 16:09:04 triviamedia /usr/local/kamailio/sbin/kamailio[16006]: CRITICAL: <core> [core/mem/q_malloc.c:502]: qm_free(): BUG: freeing already freed pointer (0x7fcd23ce5648), called from tm: h_table.c: free_cell_helper(235), first fre And here's the "bt full" of the core file: [New LWP 16003] Cannot access memory at address 0x7fcd64e1a148 Cannot access memory at address 0x7fcd64e1a140 Failed to read a valid object file image from memory.

Forcing outbound transport to TCP
by Ivan Ribakov 02 Oct '18

02 Oct '18

I’m new to Kamailio and currently evaluating it’s capabilities. One of the things I would like to be able to do is to change outbound message transport based on some dynamic logic. Kamailio setup: I’m running on a setup from this guide - http://kamailio.org/docs/tutorials/5.1.x/kamailio-install-guide-git/ <http://kamailio.org/docs/tutorials/5.1.x/kamailio-install-guide-git/> and using default configuration file. In a basic scenario of one2one call, I was able to make Kamailio to forward INVITE to callee over TCP by issuing a REGISTER request with “transport=tcp” parameter. Although it worked, as far as I understand that means all communication with the callee will be happening over TCP. I would like to be able to change transport dynamically so looking for a way to do that from config file. I tried modifying $ru/$du in the following manner, but it didn’t seem to work. # default config content if (is_method("INVITE")) { setflag(FLT_ACC); # do accounting # added to try to force TCP transport $du = $du + ";transport=tcp"; } Any pointers as to how can I modify the outbound message transport? Do I need to use some extra modules or can it be achieved with a basic setup? Thanks in advance, Ivan

Registrar Module
by Dan Quinney 01 Oct '18

01 Oct '18

Hi, So, route[REGISTRAR_1] will, when the max_contacts is reached, reply to the endpoint with a 503 error containing a "P-Registrar-Error: Too many registered contacts" header - this seems wrong to me so I've tried to work around it with route[REGISTRAR_2] which returns the right response, but, also writes "INFO: registrar [save.c:615]: test_max_contacts(): too many contacts for AOR" to the log file, which is messy. Does anyone have any pointers for doing this better? Thanks, Dan route[REGISTRAR_1] { if ( is_method("REGISTER") ) { if(isflagset(FLT_NATS)) { setbflag(FLB_NATB); setbflag(FLB_NATSIPPING); } if ($avp(maximum_contacts) != $null) { $xavp(reg=>max_contacts) = $avp(maximum_contacts); } save("location"); } return; } route[REGISTRAR_2] { if ( is_method("REGISTER") ) { if(isflagset(FLT_NATS)) { setbflag(FLB_NATB); setbflag(FLB_NATSIPPING); } if ($avp(maximum_contacts) != $null) { $xavp(reg=>max_contacts) = $avp(maximum_contacts); } save("location", "0x02"); switch ($retcode) { case -1: sl_send_reply("500", "Server Internal Error"); exit; case -2: sl_send_reply("403", "Forbidden"); exit; }; sl_send_reply("200", "OK"); } return; }

RTPEngine Question
by Wilkins, Steve 01 Oct '18

01 Oct '18

Hello All, I have an issue where Kamailio-RTPEngine-Asterisk calls work good when a softphone UAC on an IOS phone makes an Inbound call to a WebRTC client. However, if the softphone UAC is on Windows, it does not work (No Audio/Video). I noticed in the Wireshark trace that when using IOS I see STUN packets, but when using Windows I see no STUN packets. I believe this may be my issue, but I am not sure why the IOS would create STUN packets but when using Windows I get no STUN packets. Does anyone have any thoughts on what could be causing this? Thank you,

Problem with replicating dialogs using DMQ
by Jan Hazenberg 01 Oct '18

01 Oct '18

Hello, I'm trying to replicate active dialogs using the DMQ module. I see the dialogs on the other nodes but it generates a error message in the logs on all the nodes: Sep 27 10:17:31 sip04 /usr/sbin/kamailio[27367]: CRITICAL: dialog [dlg_timer.c:130]: insert_dlg_timer(): Trying to insert a bogus dlg tl=0x7efdca1bebf8 tl->next=0x7efdca14cb80 tl->prev=0x7efdca14cb80 Sep 27 10:17:31 sip04 /usr/sbin/kamailio[27367]: CRITICAL: dialog [dlg_dmq.c:309]: dlg_dmq_handle_msg(): Unable to insert dlg timer 0x7efdca1beb98 [2643:3725] Even with the timeout_avp option disabled i still see the error messages. I tested this on kamailio 5.0.3 and 5.1.3 with the same results. With debug enabled i see the correct data is replicated to the other nodes: dlg_dmq_replicate_action(): sending serialized data {"action":2,"h_entry":1328,"h_id":409,"state":4,"start_ts":1538036606,"lifetime":7200,"tag1":"1635359980","tag2":"as2d80799c","cseq1":"21","cseq2":"0","route_set1":"","route_set2":"","contact1":"sip:sipuser@10.10.10.10:1057 ;alias=10.10.10.10~1055~1","contact2":"sip:+31101234567@10.10.10.10:5060"} "lifetime":7200 is in the serialized data, and when i check on the other node with "kamcmd dlg.list" i see that the lifetime data is not updated.

registrar lookup with different URI
by Maarten Ureel 30 Sep '18

30 Sep '18

Hello I want the registar module to lookup a user with a different 'name' as the RURI. We have the extension & domain in variables, but the RURI is ext@ip-of-server, e.g. 200(a)1.1.1.1<mailto:200@1.1.1.1>, while we want to perform the lookup for 200(a)somedomain.tld<mailto:200@somedomain.tld>. We have somedomain.tld in a header, so we have it in a variable. However, if we perform the lookup like this (using Python module): lookup_result = KSR.registrar.lookup('location') We get a negative result, and the debug logs show that it tries to locate 200(a)1.1.1.1<mailto:200@1.1.1.1> - which makes sense. So according to docs you can specify an URI, however when I do this: lookup_result = KSR.registrar.lookup('location' '200(a)somedomain.tld') lookup_result is "False" and the function is not executed, according to docs because it cannot obtain the parameters for this function. How can we force the registrar module to lookup a different user?

Dialog timout reset when receiving a re-INVITE
by jenus＠cyberchaos.nl 30 Sep '18

30 Sep '18

Hello, I have a issue with setting the dialog timeout for a call. It works fine until i receive a re-INVITE. The re-INVITE seems to reset the dialog timeout back to the default value configured in the module parameters (7200 in my case). I use "dlg_set_timeout("900");" to set the timeout to 900 seconds. When i receive a re-INVITE i see the following in the debug logs: DEBUG: dialog [dlg_handlers.c:647]: get_dlg_timeout(): invalid AVP value, using default timeout This happens even with the "timeout_avp" module parameter disabled. I'm running kamailio 5.1.3. Thanks, Jan

kamailio rtp connection
by Pieter Muller 28 Sep '18

28 Sep '18

Good day all I hope Im on the right place to ask the question. Im a newbie to kamailio and have a little problem understanding how to set kamailio correctly. Scenario: VoIP Supplier (IP:161.161.252.20{Private Net}) à Connect via routing to Kamailio Server(155.155.16.2 eno2{private Net}),Kamailio Server(187.221.197.252 eno1{public facing})àconnect to PBX(public IP set in dispatcher) à connect to RTP server(Public IP) Now the problem is that if you call in Number(a)161.161.252.20 <mailto:Number@161.161.252.20> is send to kamailio, kamailio then sends it down to dispatcher IP and that PBX responds directly back via rtp server to 161.161.252.20. The 161.161.252.20 IP is private and cannot be reached from the cloud and vice versa . How do I get kamailio to be the middle man between 161.161.252.20 and RTP server(all traffic must go via the kamailio server) Is there specific modules I must load. Im running Kamailio 4.4 Any help would be muchly appreciated. Regards Pieter

Important: new module exports interface
by Daniel-Constantin Mierla 28 Sep '18

28 Sep '18

Hello, as a result of collaborative work at Kamailio Developers Meeting, we succeeded to merge the two existing module exports interface (one for kamailio modules and the other one from ser modules) in a single one. All public modules were updated, but if you have any private module then you have to update as well in order to get it compiled with the latest master. Just look at one of the modules (e.g., sl is a good option) and all the fields in mod exports structure have comments with their meaning. In short: we removed unused fields for statistics, mi commands and extra-processes (from kamailio old interface) and oncancel (from ser old interface), kept the rpc exports from ser interface and pv exports and dlopen flags from kamailio interface. The other fields were common in both interfaces, but be aware that order was also changed. If you have a module implementing the old ser interface, you also need to add the free_fixup_field in functions exports tructure -- you can just set it to 0. With this we have now a single mod exports interface in all modules, the core is also cleaner as we got rid of the various compatibility layers.

subst_hf to rewrite a contact header
by Ben Hood 27 Sep '18

27 Sep '18

Hi, I’m wondering how to use subst_hf() properly. I’m trying to debug a broken flow by manually rewriting the contact header from Contact: <sip:b73c6f29-0101-4802-afcd-efb63f1e6d8f@10.10.10.12:5090;transport=udp> to Contact: <sip:2018092417381900003@81.x.x.x> by using $var(ctct) = "<sip:2018092417381900003@81.x.x.x>"; subst_hf("Contact", “/\<.+\>/$var(ctct)\r\n/", "a”); but the result is Contact: <sip:2018092417381900003@81.x.x.x> sip:b73c6f29-0101-4802-afcd-efb63f1e6d8f@10.10.10.12:5090;transport=udp Testing the regex with an external tool appears to match all of the original header, so I’m wondering why subst_hf doesn’t appear to rewrite the entire header. Is there something I’m doing wrong? TIA, Ben

Kamailio - Asterisk integration
by denislav.tsonev＠musala.com 27 Sep '18

27 Sep '18

Hello guys, I'm following this guide: https://kb.asipto.com/asterisk:realtime:kamailio-4.0.x-asterisk-11.3.0-astdb And I have the following schema: Phone A -----> Kamailio -----> Asterisk -----> Phone B (10.0.8.249) (10.0.6.123) (10.0.3.144) (10.0.13.23) I think the flow it is like (because when UAC register to Asterisk, the contact points to Kamailio IP): 1. Phone A --> Kamailio --> Asterisk 2. Asterisk --> Kamailio --> Phone B In attachment is the pcap of the call, kamailio config. The problem is that I never receive ACK after 200 OK and call drops after 30 seconds? Kamailio version 5.1 and Asterisk version 15.1 Phones are grandstreams and also tested with microsip soft client and same results... Like "Phone A" never sends ACK back I tried different approaches to change contact header in 200 OK, because is Asterisk IP. Disable NAT handling. Different "nat_uac_test" flags, but still without success :( Also tried with this NAT detection and manage routes (again without any success) - source https://github.com/sipwise/kamailio/blob/master/etc/kamailio.cfg # Caller NAT detection route[NATDETECT] { #!ifdef WITH_NAT force_rport(); if (nat_uac_test("19")) { if (is_method("REGISTER")) { fix_nated_register(); } else { if(is_first_hop()) { set_contact_alias(); } } setflag(FLT_NATS); } #!endif return; } # RTPProxy control and signaling updates for NAT traversal route[NATMANAGE] { #!ifdef WITH_NAT if (is_request()) { if(has_totag()) { if(check_route_param("nat=yes")) { setbflag(FLB_NATB); } } } if (!(isflagset(FLT_NATS) || isbflagset(FLB_NATB))) return; if(nat_uac_test("8")) { rtpproxy_manage("co"); } else { rtpproxy_manage("cor"); } if (is_request()) { if (!has_totag()) { if(t_is_branch_route()) { add_rr_param(";nat=yes"); } } } if (is_reply()) { if(isbflagset(FLB_NATB)) { if(is_first_hop()) set_contact_alias(); } } #!endif return; } Thanks in advance Denislav Raychev Tsonev | Integration and Infrastructure Engineer | Musala Soft JSC www.musala.com | t: +359 2 969 58 21 | m: +359 878 270 965 | f: +359 2 969 58 22 World Trade Center, 36 Dragan Tsankov blvd., Sofia 1057, Bulgaria

Problem with replicating dialogs using DMQ
by jenus＠cyberchaos.nl 27 Sep '18

27 Sep '18

Hello, I'm trying to replicate active dialogs using the DMQ module. I see the dialogs on the other nodes but it generates a error message in the logs on all the nodes: Sep 27 10:17:31 sip04 /usr/sbin/kamailio[27367]: CRITICAL: dialog [dlg_timer.c:130]: insert_dlg_timer(): Trying to insert a bogus dlg tl=0x7efdca1bebf8 tl->next=0x7efdca14cb80 tl->prev=0x7efdca14cb80 Sep 27 10:17:31 sip04 /usr/sbin/kamailio[27367]: CRITICAL: dialog [dlg_dmq.c:309]: dlg_dmq_handle_msg(): Unable to insert dlg timer 0x7efdca1beb98 [2643:3725] Even with the timeout_avp option disabled i still see the error messages. I tested this on kamailio 5.0.3 and 5.1.3 with the same results. With debug enabled i see the correct data is replicated to the other nodes: dlg_dmq_replicate_action(): sending serialized data {"action":2,"h_entry":1328,"h_id":409,"state":4,"start_ts":1538036606,"lifetime":7200,"tag1":"1635359980","tag2":"as2d80799c","cseq1":"21","cseq2":"0","route_set1":"","route_set2":"","contact1":"sip:sipuser@10.10.10.10:1057;alias=10.10.10.10~1055~1","contact2":"sip:+31101234567@10.10.10.10:5060"} "lifetime":7200 is in the serialized data, and when i check on the other node with "kamcmd dlg.list" i see that the lifetime data is not updated. Thanks, Jan

create domain "on the fly" in registrar modukle
by Maarten Ureel 27 Sep '18

27 Sep '18

I'm building a setup with FreeSWITCH and Kamailio 5.2 but I'm having troubles in handling the registrations for multiple domains. So far I have in my config these related settings: # Disable database completely modparam("usrloc", "db_mode", 0) # Take domain into account when saving modparam("usrloc", "use_domain", 1) # Preload location table modparam("usrloc", "preload", "location") I'm using the app_python module; when performing the registrar save like this: KSR.registrar.save(KSR.pv.get('$fd'), 1) It fails, the debug shows that it cannot find the domain that the SIP user has here. When I use: KSR.registrar.save('location', 1) The phone registers just fine; however I'm bothered by the fact that the documentation states that you should specify the domain as a parameter. Is it OK if everything is in one 'location' domain? How can I let Kamailio know what domains exist (where does Kamailio get this information from)? We have a unique domain for every customer, like g123.ctx.ourcompany.tld. Kind regards Maarten Ureel

Adding new rtpproxy instance without restarting Kamailio
by Pintu Lohar 27 Sep '18

27 Sep '18

Hi All, I have a very basic question. Is there any way to add new rtpproxy instance without restarting Kamailio? As per my understanding, we can reload the dispatcher table when Kamailio server is running with kamctl dispatcher reload but do we have any such for rtpproxy list also from db when rtpproxy table ? Below is my rtpproxy related config, load from DB , #Once RTPProxy was found unreachable and marked as disabled, #the rtpproxy module will not attempt to establish communication to RTPProxy for rtpproxy_disable_tout seconds. modparam("rtpproxy", "rtpproxy_disable_tout", 120) #only for local host. modparam("rtpproxy", "timeout_socket", "xmlrpc:http://127.0.0.1:8000/RPC2") modparam("rtpproxy", "db_url", "mysql://kamailio:xxxxxxxx@10.xx.xx.xx /kamailio") modparam("rtpproxy", "table_name", "rtpproxy") #enable marker for sdp modification by rtpproxy modparam("rtpproxy", "nortpproxy_str", "a=sdpmangled:yes\r\n") my current instance : ./kamcmd rtpproxy.list { setid: 0 url: udp:xxx.xx.xxx.xxx:7722 index: 2 disabled: 0 weight: 1 recheck: 0 } Db +----+-------+--------------------------+-------+--------+-------------+ | id | setid | url | flags | weight | description | +----+-------+--------------------------+-------+--------+-------------+ | 1 | 0 | udp:XXX.XXX.XXX.XXX:7722 | 0 | 1 | | +----+-------+--------------------------+-------+--------+-------------+ I already explored ./kamcmd rtpproxy.enable command , but it seems that this command is useful for re-enabling or disabling existing rtpproxy instance . My purpose is to add new rtpproxy instance when Kamailio is running. Thanks in advance. Any suggestion would very helpful. Thanks & Regards Pintu

KAMAILIO 5.1 - how to make a full redundancy of two kamailio Proxy server ?
by yboujraf＠by-systems.be 26 Sep '18

26 Sep '18

Dear All, I am currently thinking to use TWO (2) Kamailio Proxy server in redundancy. The system is : * I have one (1) public address * Two (2) Kamailio Servers with two different IP address My questions are : * What I need to add in front of the two Kamailio servers to be sure sip phone will be connected through the public ip address to one of the kamailio server at time. I have seen we could enable "cluster module" to sync the dabase of the two (2) kamailio server at the same time but not for the request. * Script to add to be sure the kamailio servers are correctly configured.
