Hello! I need to disable topos for one specific SIP trunk (in-out), it looks like it’s enough to use event_route with IP address filtering. But for some reason, the incoming INVITE from the peer still gets processed by topos and I also don’t see a mention of [msg-incoming] in the logs, only this: WARNING: <script>: [msg-outgoing] OPTIONS/you/1.1.1.1 Code snippet: loadmodule "topos.so" modparam("topos", "db_url", DBURL) modparam("topos", "contact_mode", 1) modparam("topos", "header_mode", 1) modparam("topos", "methods_noinitial", "OPTIONS,SUBSCRIBE,PUBLISH") modparam("topos", "dialog_expire", 7210) modparam("topos", "rr_update", 1) modparam("topos", "event_mode", 5) /* 1 - execute event_route[topos:msg-outgoing] 2 - execute event_route[topos:msg-sending] 4 - execute event_route[topos:msg-incoming] 8 - execute event_route[topos:msg-receiving] */ request_route { .... event_route[topos:msg-outgoing] { if ( $sndto(ip) == "1.1.1.1" ) { xlog("L_WARN","[msg-outgoing] $rm/$rU/$sndto(ip) \n"); drop; } } } event_route[topos:msg-incoming] { if ( $si == "1.1.1.1" ) { xlog("L_WARN","[msg-incoming] $rm/$rU/$si \n"); drop; } } # kamailio -v version: kamailio 5.7.1 (x86_64/linux) 1cf389-dirty -- BR, Denys Pozniak

t_check_trans in Lua

by nizam＠ctapps.com

Dear experts, Would appreciate if anyone can explain why in the given sample Lua script the 'Handle Retransmission' block checks the return code of t_check_trans (if KSR.tm.t_check_trans == 0 then), but in the Kamailio native config standard file if just calls the t_check_trans() function without checking the return code. What is the intention here and how does it work? Thank you in advance. Handle retransmission script from native config file: if (!is_method("ACK")) { if(t_precheck_trans()) { t_check_trans(); exit; } t_check_trans(); } Handle retransmission from sample Lua script: if not KSR.is_ACK() then if KSR.tmx.t_precheck_trans() > 0 then KSR.tm.t_check_trans(); return 1; end if KSR.tm.t_check_trans() == 0 then return 1; end end

Setting $du to websocket-secure

by James Browne

How can I set the destination URI for an INVITE to be a websocket-secure destination? Is it possible? Summary I've a proxy with tcp_connection_match=1, but websocket URIs always have transport=ws (never transport=wss) in them, so relaying a call to a WSS connection always fails. I tested running kamailio 6.0.0-dev2 compiled from a commit made this week. This proxy server uses nathelper rather than outbound module. Detail We know that "transport=ws" is used for both WS and WSS. I've a proxy server that receives an INVITE for a WSS destination, and this proxy supports both WS and WSS. This proxy server must have core parameter tcp_connection_match=1 set, and this leads the t_relay() to fail. When an INVITE comes, these are the steps. - The URI is something like sip:user@anonymous.invalid;alias=198.51.100.10~52833~6;transport=ws. - First handle_ruri_alias() removes the alias (which has ~6 in it, for wss) and sets the $du to something like sip:198.51.100.10:52833;transport=ws. - Then loose_route_preloaded() processes the Route header fields and forces the outbound socket to the TLS websocket one. - Then t_relay() fails to relay the INVITE and responds with 477 or 500. If, however, there's a non-TLS websocket connection open to the proxy, the INVITE would be erroneously relayed over that (using the wrong kamailio-side TCP port). I can go deeper with testing if required. I wonder whether this is a bug. James

secsipid and secsipid_proc module RPM build

by Володимир Іванець

Hello! I was wondering if someone was trying to build Kamailio RPM packages containing modules secsipid and secsipid_proc and faced the same problem. I compiled secsipidx library and copied secsipid.h, libsecsipid.h as well as libsecsipid.a files into the source directory of secsipid_proc module. And when I'm trying to build RPM packages, I get the following error: CC (gcc) [M secsipid_proc.so] secsipid_proc_mod.o secsipid_proc_mod.c:28:10: fatal error: secsipid.h: No such file or directory #include <secsipid.h> ^~~~~~~~~~~~ compilation terminated. make[2]: *** [../../Makefile.rules:100: secsipid_proc_mod.o] Error 1 make[1]: *** [Makefile:508: modules] Error 1 make[1]: Leaving directory '/builddir/build/BUILD/kamailio-5.8.2/src' make: *** [Makefile:34: every-module] Error 2 Thanks a lot!

Permissions module - automatic reload

by Sergio Charrua

Hi all, Just need some clarifications about the Permissions module: I currently use it with db_mode = 1 and was expecting that the parameter "trusted_cleanup_interval" would refresh the cache tables every X seconds, but apparently this is not the case. I was looking for a way for Kamailio to automatically reload the address table into memory every 5 minutes, for example, and I (mis)understood that "trusted_cleanup_interval" would do the trick, but it doesn't work as expected. Question: is there any command, besides kamcmd, to automatically reload the permissions table? I would like to avoid having to add a line in the crontab.... Atenciosamente / Kind Regards / Cordialement / Un saludo, *Sérgio Charrua*

Using a different OpenSSL

by David Cunningham

Hello, We have compiled openssl 3.0.9 from source because it's FIPS validated, and want to use it with Kamailio. The server also has the Ubuntu openssl 3.0.2 package installed. Does anyone know how we can tell Kamailio to use the openssl library in /opt/openssl/lib64, and how we can verify that it really is using it? Thanking you in advance, -- David Cunningham, Voisonics Limited http://voisonics.com/ USA: +1 213 221 1092 New Zealand: +64 (0)28 2558 3782

How to restrict Kamailio adding Local VIA header

by panda.paresh＠gmail.com

Hi All, I am trying to replay a request to the destination via Kamailio, and I am using t_relay_to_tcp for that , but in that case Kamailio is adding its own address as the top VIA header. Is there a way I can instruct Kamailio not to add local via header ?

http_async and tm

by alexis

Hello all, context first, we have an REST API that performs queries to external devices in the network (diameter to DRA's, REST to different servers) and based on n conditions returns the content for a Contact header to be used in a SIP 302. Now we're consuming this API with http_client (synchronously) and as there's no way to speed up the API (pipeline executions, delays on external api's etc etc) we're hitting a limit where all children become busy waiting for the API to answer. So i decided to move to http_async_client and started working on it on the lab with this first and base concept to test. request_route { #for testing purposes only if(is_method("ACK")){ exit; } $http_req(all) = $null; $http_req(suspend) = 1; $http_req(timeout) = 500; $http_req(method) = "POST"; $http_req(hdr) = "Content-Type: application/json"; jansson_set("string", "event", "sip-routing", "$var(cre_query)"); xlog("L_INFO","API ASYNC ROUTING REQUEST: $var(cre_query)\n"); $http_req(body) = $var(cre_query); t_newtran(); http_async_query("http://192.168.86.128:8000/", "CRE_RESPONSE"); } http://192.168.86.128:8000/ receives the POST, randomly creates a delay between 0.5 and 1 second and responds (simulating the real api with an excess delay to probe the concept) Then route[CRE_RESPONSE] { if ($http_ok && $http_rs == 200) { xlog("L_INFO","CRE RESPONSE: $http_rb\n"); # for testing purpose, Contact content will be replaced from the received api response append_to_reply("Contact: <sip:1234@google.com>\r\n"); send_reply(302,"Moved Temporarily"); exit; } send_reply(500, "Internal error"); exit; } INVITE is received and processed, API is called, after API response, 302 is replied and then an ACK (ignored by now). Situation is that the 302 retransmitted 37 1519.846253067 192.168.86.34 → 192.168.86.128 SIP/SDP 585 Request: INVITE sip:service@192.168.86.128:5060 | 38 1519.848100380 192.168.86.128 → 192.168.86.34 SIP 318 Status: 100 Trying | 39 1520.094997642 192.168.86.128 → 192.168.86.34 SIP 407 Status: 302 Moved Temporarily | 40 1520.102323728 192.168.86.34 → 192.168.86.128 SIP 453 Request: ACK sip:service@192.168.86.128:5060 | 41 1520.591300933 192.168.86.128 → 192.168.86.34 SIP 407 Status: 302 Moved Temporarily | 42 1521.591061065 192.168.86.128 → 192.168.86.34 SIP 407 Status: 302 Moved Temporarily | 43 1523.591227956 192.168.86.128 → 192.168.86.34 SIP 407 Status: 302 Moved Temporarily | 18(24) DEBUG: tm [t_reply.c:1703]: t_retransmit_reply(): reply retransmitted. buf=0x7f6d79745dc0: SIP/2.0 3..., shmem=0x7f6d75187fd8: SIP/2.0 3 18(24) DEBUG: tm [t_reply.c:1703]: t_retransmit_reply(): reply retransmitted. buf=0x7f6d79745dc0: SIP/2.0 3..., shmem=0x7f6d75187fd8: SIP/2.0 3 18(24) DEBUG: tm [t_reply.c:1703]: t_retransmit_reply(): reply retransmitted. buf=0x7f6d79745dc0: SIP/2.0 3..., shmem=0x7f6d75187fd8: SIP/2.0 3 18(24) DEBUG: tm [timer.c:634]: wait_handler(): finished transaction: 0x7f6d75184cc8 (p:0x7f6d74f600c8/n:0x7f6d74f600c8) 18(24) DEBUG: tm [h_table.c:132]: free_cell_helper(): freeing transaction 0x7f6d75184cc8 from timer.c:643 Any help to avoid the retransmission and make the transaction just finish right after the 302 will be appreciated. regards

apply keepalive to only udp

by James Lipski

Hello, I wanted to know if this can be accomplished, or if I'm doing something wrong. What I'm hoping to accomplish is to have kamailio periodically send OPTIONS packets to endpoints that are connected over UDP only. As of right now, I currently have the following configured under usrloc: modparam("usrloc", "timer_interval", 5) modparam("usrloc", "timer_procs", 2) modparam("usrloc", "use_domain", MULTIDOMAIN) modparam("usrloc", "db_url", DBURL) modparam("usrloc", "db_mode", 0) modparam("usrloc", "ka_mode", 1) modparam("usrloc", "ka_method", "OPTIONS") modparam("usrloc", "ka_from", "sip:ping@sip-domain.com") modparam("usrloc", "ka_domain", "sip-domain.com") modparam("usrloc", "ka_timeout", 125) modparam("usrloc", "ka_interval", 60) With these parameters, all endpoints will be sent OPTIONS packets periodically as expected. When setting "ka_mode" to "4", as expected, endpoints registered with UDP only receive OPTIONS packets; which is what I wanted. The issue that I'm having with these parameters is that endpoints registered with anything other that UDP are triggering a contact-expired event after a little over 2 minutes. I have the registrar set to 3600 as an expiry; I'm assuming the contact is expiring due to the "ka_timeout" value. -------------------------- Is there a way to only have keep-alive packets/ and timeouts apply to endpoints registered on UDP? Thank you.

Kamailio integration with REST services

by Sergio Charrua

Hi all! I need to integrate a REST Service with Kamailio. Integration is easy, not a problem, but my concern is that the REST Services has a JWT token authentication required for each request, common to many (it not all) REST Services. So, it is required to POST for authentication (username and password) and once I get authentication done, and receive a JWT token, I will need to use this token in all other requests to the REST Service. The token is valid for 24h. My question is: - how to save the token for use during 24h, on all calls/sessions, without the need to authenticate on every call? - how to detect the token has expired and re-authenticate? I looked for some modules, but could not find any that suited me. I am thinking of executing a Python script for this, but concerned about latency and PDD.... Any thoughts? Any suggestions? Any known best-practice? Atenciosamente / Kind Regards / Cordialement / Un saludo, *Sérgio Charrua*

Limiting Video calls(Volte to video conversion)

by dushy

Hello All, I am trying to limiting the number of video calls (converting Volte to Vilte). To reduce traffic on the enodeb. Its like if there are 10 volte calls going on then I should be able to limit the number calls that can be converted to Vilte. I tried to write a route in kamailio_pcscf.cfg using module ims_dialog. But it doesnt work and get some errors while doing a modparam. Tried another method of counting eRAB at eNB (ENBUEID and ERABID pair with qci-2). This worked, but after sometime the extra call got established. Looks like traffic is going through qci 9 bearer. Is there any method where we can achieve this. Thanks in Advance. Regards, Dushyanth

Re: certificate verify failed (sni: unknown) integration with ms teams

by Muhammad Sohaib

Hi Batanai, After disabling #!define WITH_NAT in Kamailio, calls from the Asterisk endpoint to Microsoft Teams are functioning correctly. Both inbound and outbound calls exhibit proper two-way audio and no disconnection issues but there is no Bye when hangup from ms teams. However, I am encountering a problem with outbound calls originating from Microsoft Teams. When a call is placed from MS Teams, the recipient's phone rings as expected. Once the call is answered, Microsoft Teams disconnects the call immediately. The root of the issue seems to be that the ACK message is not being sent or received properly. As a result, Microsoft Teams does not receive the ACK, leading to an immediate call termination. Additionally, Asterisk does not receive a BYE message from Kamailio. *Summary of the Issue:* - *Inbound Calls*: From Asterisk to MS Teams work fine, with full audio and no disconnections but no BYE from ms teams. - *Outbound Calls*: From MS Teams to Asterisk result in the call being disconnected immediately after being answered due to a missing ACK, and Asterisk does not receive a BYE message. Thanks, On Tue, Aug 27, 2024 at 5:45 PM Batanai Musiiwa <batanai.musiiwa(a)etel.co.zw> wrote: > Hi @ > Muhammad.

I have mo media and I must park

by Alexandru Covalschi

Hello list! Please help me understand if putting my b2bua in sensory deprivation is actually the best approach to punish it for sole reason of its existence. The background of this horror story is pretty cliche, call center needs a way to infinitely expand, so I'm building a scaling telephony core. Our main protagonist is an innocent b2bua with a very grounded backstory: step 0: receive external instruction to start a call step 1: originate step 2: park step 3: play moh until: - - a) told to pass it to other component - - b) told to hang up - - c) hang up on local timeout A simplified diagram of the call flow looks something like this (repeating names are same components): ### Signaling ### Remote Destination ^ Kamailio-external ^ Freeswitch-originator V Freeswitch- queue V Kamailio-local V Agent ### end of signaling ### ### Media ### Remote Destination ^ Rtpengine-external ^ Freeswitch-originator V Freeswitch-queue V Rtpengine- local V Agent ### end of media ### Due to specifics of the setting, re-negotiating the media and any non-essential signaling with remote destination is a very much last resort. And, as you can imagine, after step3a (pass it to other component), the character development of Freeswitch-originator service stops completely. Well, at least it is doing an honest job by playing the music on hold, which a little bit justifies its presence on the media path. But not for long. In the world of near future, pull request number 3956 is merged with the master branch, exposing the rtpengine API and leaving me no reason not to move MoH to a kernel media player. At this moment I feel a wild urge to get rid of Freeswitch-originator at all, but then I read the sources for mohq and dialog to remind myself that Kamailio is a proxy and proxies can't do this... So I fill b2bua's dialplan with 387.44 million lines of hateful comments and remind it to rcvonly every time it tries to warn the others about the grim fate. When the queue designates an agent to his call, theoretically I don't even need the second freswitch as well - if agen't media session has been established (sometimes ICE take tooo long) with Rtpengine- local, I can bridge their media sessions using publish and subscribe. I'd like to ask your opinion, list: do you see any plotholes potential issues with such deisgn? I'd honestly like to set Freeswitch to bypass-media, so it wont' waste ports and cpu for nothing at all. Are there any issues if I add body for the iniitial invite in the request_route as if it was received in there? Maybe there's a better way, overall? Any critique is welcome! Thank you -- AC

How to invoke RTPengine for re-Invite 200 OK within dialog

by Shah Hussain Khattak

Hello Experts, I need your advice on the following issue if you can kindly help. I am working on a hold call flow: UA - > Kamailio (RTP Engine) - > FS initial call establishes fine, RTP engine is invoked and SDP media IP is modified correctly. Then 1. I am receiving a hold re-invite with a send-only 2. I see Kamailio is changing the media IP in the SDP (with my RTP engine IP) when it sends the Invite to my core FS server. 3. FS sends 200 OK with a=recvonly 4. Kamailio relays the message as it is to the other leg. can someone advise me, on how can I invoke rtpengine at step 4, so the SDP is sent with my media server IP in the 200 OK? --- 200 OK from FS ---- SIP/2.0 200 OK Via: SIP/2.0/UDP 13.54.01.02:5060;branch=z9hG4bKd2e8.8a573af8d927f67c1db4550676f8be88.0;i=1 Via: SIP/2.0/TCP 192.168.10.117:51280;received=218.33.01.02;rport=51280;branch=z9hG4bKPj7d1d8968830d4ed3922eec7da7cdc17c;alias Record-Route: <sip:13.54.01.02:5060;r2=on;lr=on> Record-Route: <sip:13.54.01.02;transport=tcp;r2=on;lr=on> From: <sip:0403225908@trunk.xyz.corp>;tag=6a180ffa7f824972a2c59ba47f293acb To: <sip:+61285038000@trunk.xyz.corp>;tag=DZrpcpgS1BDKF Call-ID: 4154062196634c34a2dbcb6b612bf44c CSeq: 12263 INVITE Contact: <sip:+61285038000@54.88.54.88:5060;transport=udp> User-Agent: UserAgentX/v1.0 Accept: application/sdp Allow: INVITE, ACK, BYE, CANCEL, OPTIONS, MESSAGE, INFO, UPDATE, REGISTER, REFER, NOTIFY Require: timer Supported: timer, path, replaces Session-Expires: 1800;refresher=uac Content-Type: application/sdp Content-Disposition: session Content-Length: 266 v=0 o=FreeSWITCH 1724635755 1724635757 IN IP4 54.88.54.88 s=FreeSWITCH c=IN IP4 54.88.54.88 t=0 0 m=audio 21202 RTP/AVP 8 101 a=rtpmap:8 PCMA/8000 a=rtpmap:101 telephone-event/8000 a=fmtp:101 0-15 a=recvonly a=ptime:20 a=rtcp:21203 IN IP4 54.88.54.88 --- 200 OK relayed towards the UA ---- 2024/08/26 17:22:39.923639 172.16.8.126:5060 -> 218.33.78.33:51280 SIP/2.0 200 OK Via: SIP/2.0/TCP 192.168.10.117:51280;received=218.33.01.02;rport=51280;branch=z9hG4bKPj7d1d8968830d4ed3922eec7da7cdc17c;alias Record-Route: <sip:13.54.01.02:5060;r2=on;lr=on> Record-Route: <sip:13.54.01.02;transport=tcp;r2=on;lr=on> From: <sip:0403225908@trunk.xyz.corp>;tag=6a180ffa7f824972a2c59ba47f293acb To: <sip:+61285038000@trunk.xyz.corp>;tag=DZrpcpgS1BDKF Call-ID: 4154062196634c34a2dbcb6b612bf44c CSeq: 12263 INVITE Contact: <sip:+61285038000@54.88.54.88:5060;transport=udp> User-Agent: UserAgentX/v1.0 Accept: application/sdp Allow: INVITE, ACK, BYE, CANCEL, OPTIONS, MESSAGE, INFO, UPDATE, REGISTER, REFER, NOTIFY Require: timer Supported: timer, path, replaces Session-Expires: 1800;refresher=uac Content-Type: application/sdp Content-Disposition: session Content-Length: 266 v=0 o=FreeSWITCH 1724635755 1724635757 IN IP4 54.88.54.88 s=FreeSWITCH c=IN IP4 54.88.54.88 t=0 0 m=audio 21202 RTP/AVP 8 101 a=rtpmap:8 PCMA/8000 a=rtpmap:101 telephone-event/8000 a=fmtp:101 0-15 a=recvonly a=ptime:20 a=rtcp:21203 IN IP4 54.88.54.88 my configs for within dialog route: ##### route[WITHINDLG] { append_hf("X-Test-Header: route_WITHINDLG\r\n"); if (has_totag()) { if (loose_route()) { if (is_method("BYE")) { setflag(FLT_ACC); # do accounting ... setflag(FLT_ACCFAILED); # ... even if the transaction fails } if (is_method("ACK")) { xlog("L_INFO", "Relaying ACK\n"); } if (is_method("INVITE|UPDATE")) { if (has_body("application/sdp") && search_body("m=image") && search_body("T38")) { xlog("L_INFO", "T.38 re-INVITE detected, skipping rtpengine invocation\n"); } else { xlog("L_INFO", "Non-T.38 INVITE detected, invoking rtpengine\n"); rtpengine_manage("replace-origin replace-session-connection"); } } route(RELAY); } else { if (is_method("SUBSCRIBE") && uri == myself) { route(PRESENCE); exit; } if (is_method("ACK")) { if (t_check_trans()) { t_relay(); exit; } else { exit; } } sl_send_reply("404","Not here"); } exit; } } ##### looking forward to your usual guidance.

socket names for command line parameter "listen"

by Xenofon Karamanos

Hello all, I wanted to inform you about an upcoming change regarding the syntax we use for defining socket names in the listen (-l) command line argument. Current Syntax: -l udp:10.10.10.10:5060/11.11.11.11:5060 Proposed Options: 1. -l udp:10.10.10.10:5060/11.11.11.11:5060=s1 2. -l s1=udp:10.10.10.10:5060/11.11.11.11:5060 ( A draft PR about this option can be found in https://github.com/kamailio/kamailio/pull/3954) [https://opengraph.githubassets.com/69f8a4a1d2c8988372b4942f84bde95de94502d2…]<https://github.com/kamailio/kamailio/pull/3954> main: Add support for naming socket in cli by xkaraman · Pull Request #3954 · kamailio/kamailio<https://github.com/kamailio/kamailio/pull/3954> Pre-Submission Checklist Commit message has the format required by CONTRIBUTING guide Commits are split per component (core, individual modules, libs, utils, ...) Each component has a single... github.com Please note that the socket name (s1) in both options is/should be optional. The change will allow for better clarity and flexibility when defining sockets, particularly when a name needs to be assigned and match the config file style. I would appreciate your feedback on which syntax you find more intuitive or any concerns you might have with these options. Your input is important to ensure a smooth transition.

Suspected memory leak in module ims_registrar_pcscf

by whliu＠citictel.com

Hi, I just tried to send numbers of SIP register to kamailio (release 5.8.2). It is reported that there are some memory leakage in shared memory after the expiry of all the registration sessions. After drill down the code. function save_pending(...) is called. (in ims_registrar_pcscf/save.c). Inside that function, it seems that "sec_verify_params" is not deallocated upon the function completes. Findings: - sec_verify_params uses the result from function cscf_get_security_verify(...) - Function cscf_get_security_verify(...) returns the result of function parse_sec_agree(...) - Function parse_sec_agree(...) returns "params" where "shm_malloc(...)" is called It seems that the memory pointed by 'sec_verify_params' is not further referenced by others. Should shm_free(...) be called when leaving function save_pending(...) in order to free the unused memory of 'sec_verify_params'? Please advice. Thank you. Regards, Hong

push server tcp problem

by Bernd Krueger-Knauber

Hi, I implemented an apple and android push server/proxy with kamailio 5.8.1. The server/proxy is transparent. It works fine with UDP, since the registration after the push comes from the same ip and port. So t_continue works without problems. (We use the new registration as signal thet the phone is ready) If we use tcp at the client, he gets the push, wakes up and send the new registration on an other port. The SIP stack uses now an other connection. t_continue fails, because it uses the old data of the original invite acccording to the first registration. Is it possible to change the stored connection values according to the new registration data? Best regards, Bernd

low performance with udp_children and async_workers

by elhar.mohamed＠gmail.com

Hello, Based on business requirements, 35% of invites should be handled by async_workers and 65% with be handled by main children. The target is 1500cps. I'm using the following conf : children=64 async_worker=128 when doing performance tests using SIPp, I figured out the 1500cps is well supported by the conf above, but when I updated the data in database to not use anymore async workers, the cps is getting decreased and it was between 200 and 500. This a client requirements is to be able to enable/disable feature that needs to be handled by async workers. Could you please help me on this? Thanks in advance

Inbound call to webRTC failing with TCP/TLS connection (id: 0) for WebSocket could not be found

by hollis.rhonda＠gmail.com

We're seeing an issue where some webRTC clients are not receiving inbound calls. Kamailio logs show the following error: WARNING: {1 609669922 INVITE BW152025538120824-895739618(a)10.103.43.11}: <core> [core/msg_translator.c:3007]: via_builder(): TCP/TLS connection (id: 0) for WebSocket could not be found ERROR: {1 609669922 INVITE BW152025538120824-895739618(a)10.103.43.11}: <core> [core/msg_translator.c:2086]: build_req_buf_from_sip_req(): could not create Via header ERROR: {1 609669922 INVITE BW152025538120824-895739618(a)10.103.43.11}: tm [t_fwd.c:484]: prepare_new_uac(): could not build request ERROR: {1 609669922 INVITE BW152025538120824-895739618(a)10.103.43.11}: tm [t_fwd.c:1764]: t_forward_nonack(): failure to add branches DEBUG: {1 609669922 INVITE BW152025538120824-895739618(a)10.103.43.11}: tm [t_funcs.c:358]: t_relay_to(): t_forward_nonack returned error -2 (-2) DEBUG: {1 609669922 INVITE BW152025538120824-895739618(a)10.103.43.11}: tm [t_funcs.c:376]: t_relay_to(): -2 error reply generation delayed It seems to be happening after the client has been connected to Kamailio for more than 24 hours. The socket connection details look correct in the external DB and in the output of ws.dump, core.tcp_list, and ul.dump. A restart of Kamailio or a reload of the webRTC client, triggering a new websocket connection, will clear the issue. However, we haven't been able to determine exactly when and why a client ends up in this state. While a client is in this state, REGISTER requests are still handled successfully, they can make outbound calls and TCP keepalives from the client are working. I'm still working on trying to debug this with GDB so I can see what the value of send_info is in https://github.com/kamailio/kamailio/blob/master/src/core/msg_translator.c#…, but I wasn't having luck with multiple child processes running, and now my client has reloaded and is working again. I've restarted Kamailio with a single child process, so when it does start failing again, I may have better luck with GDB. Any thoughts on what might be causing clients to get into this state? Whatever additional information I can provide that might help, I'm happy to share. Thanks!

TLS module doesn't support TLSV1

by o.atef＠fiberme.com

Hello Brothers, I've installed kamailio throw "apt install" on Debian and it's installed version: kamailio 5.6.3 (x86_64/linux). Now I've a big problem that kamailio cannot running with TLSv1 and it has to be TLSv1.2+ as tls.cfg doc said: # We do not enable anything else than TLSv1.2+ # over the public internet. Clients do not have # to present client certificates by default. How could I avoid this restriction please to enable TLSv1? Thank you,

Incoming call with one one way audio and ctting off after thirty seconds

by palany

I have integrated Microsoft teams and freepbx using Kamailio version 5.8 as my SBC. Calls from freepbx to teams are working fine with audio and I am having challenges with calls from teams to freepbx. The calls rings and after answering there is only way audio and the call drops off after thirty seconds. My pbx is behind a microtik router and I have port forwarded my sip port and rtp ports to freepbx and have also disabled sip alg. My Kamailio is hosted in AWS. I have attached both my pcap from Kamailio, freepbx and my Kamailio.cfg. I am thinking It's a misconfiguration challenge or something else. Please help I am failing to see my challenge.

Kamailio hangs on get_profile_size method.

by satyaprakash ch

HI, We are facing a hang issue with Kamailio for the get_profile_size method. Randomly, the Kamailio got hangs, and the CPU went 100%. During the hanging time, we generated the TRAP and we could see that the hang happened on the get_profile_size method. We are getting this hang randomly in dlg_profile.c of the following lines: The hang occurs, causing the CPU to spike to 100% at one of the following lines randomly: 1. if(value->len == ph->value.len && memcmp(value->s, ph->value.s, value->len) == 0) { 2. ph = ph->next; 3. while(ph != profile->entries[i].first); During our analysis, we found that PROCESS ID 7608 gets a spike of 100% utilization. We suspect there may be an issue with the processing of the 'ph' variable, but we couldn't identify the root cause. I've attached the Kamailio TRAP for further details. Could you please suggest what might be causing this problem and how we can resolve it? Thank you.

Dialog timer reset on UPDATE

by Alex Balashov

Hi, I have a dialog where I have set: dlg_set_property("timeout-noreset"); But it seems the timeout is reset anyway when handling an in-dialog UPDATE request, at least, on Kamailio 5.5.4. This does not seem to happen with reinvites. I haven't been able to get more information thus far, other than to be able to say that there is nothing unusual about the UPDATE request and there are no additional errors at log level 2. I was wondering if anyone else has encountered this. -- Alex -- Alex Balashov Principal Consultant Evariste Systems LLC Web: https://evaristesys.com Tel: +1-706-510-6800

app_python3 method not found or is not callable

by Westhuis, Johannes

Hi, we are using kamailio with app_python3. It works very good, but in some cases, there are error logs stating: app_python3 [python_exec.c:91]: apy_exec(): <python method> not found or is not callable It happens sporadically, and a restart of kamailio fixes it. As far as i can see it might be linked to concurrent arrival of several messages. Best regards, Johannes # kamailio -v version: kamailio 5.5.6 (x86_64/linux) flags: USE_TCP, USE_TLS, USE_SCTP, TLS_HOOKS, USE_RAW_SOCKS, DISABLE_NAGLE, USE_MCAST, DNS_IP_HACK, SHM_MMAP, PKG_MALLOC, Q_MALLOC, F_MALLOC, TLSF_MALLOC, DBG_SR_MEMORY, USE_FUTEX, FAST_LOCK-ADAPTIVE_WAIT, USE_DNS_CACHE, USE_DNS_FAILOVER, USE_NAPTR, USE_DST_BLOCKLIST, HAVE_RESOLV_RES, TLS_PTHREAD_MUTEX_SHARED ADAPTIVE_WAIT_LOOPS 1024, MAX_RECV_BUFFER_SIZE 262144, MAX_URI_SIZE 1024, BUF_SIZE 65535, DEFAULT PKG_SIZE 8MB poll method support: poll, epoll_lt, epoll_et, sigio_rt, select. id: compiled on 12:01:03 Jul 22 2024 with gcc 10.2.1

We have this setup with 2 proxy servers with DMQ enabled, but the issue only occurs on one proxy. When the Kamailio proxy hangs, no logs are written. If you have any suggestions to resolve this issue, please help. Thanks.

Multiple TLS connections to the same IP:Port

by Nick Digalakis

Hello everyone, I am trying to use a single Kamailio server to register to multiple MS Teams Direct Routing endpoints. The config snippet I am using is this: sht_iterator_start("i1", "teams-endpoints"); while(sht_iterator_next("i1")) { $var(teams_endpoint) = $shtitkey(i1); $xavp(tls=>server_name) = $var(teams_endpoint); $xavp(tls[0]=>server_id) = $var(teams_endpoint); $uac_req(method)="OPTIONS"; $uac_req(ruri)="sip:sip.pstnhub.microsoft.com:5061;transport=tls"; $uac_req(furi)="sip:" + $var(teams_endpoint); $uac_req(turi)="sip:sip.pstnhub.microsoft.com:5061;transport=tls"; $uac_req(hdrs)="Contact: <sip:" + $var(teams_endpoint) + ":" + "5061" + ";transport=tls>\r\n"; ### Create a unique Call-ID based on the Timestamp and the Message Body in MD5 $var(unhashed_cid) = $TV(Sn) + $mb + ""; $uac_req(callid)=$(var(unhashed_cid){s.md5}); uac_req_send(); } sht_iterator_end("i1"); When the HTable has only one endpoint, everything works fine. When I add a second endpoint, the first one continues to work but the second one failing with the error from Microsoft: Q.850;cause=63;text="85babcde-e0b5-4a85-8f4a-12345678c9ae;SBC certificate is not issued correctly. Provided trunk FQDN 'endpoint-02.domain.com' is not included in certificate's CN or SAN list. Certificate allows following FQDNs only: endpoint-01.domain.com. After some digging around, I realized that all endpoint after the first fail because Kamailio is re-using the same TLS connection for all subsequent OPTIONS as well, but of course the connection has been established with the certificate of the first endpoint. I have tested the certificates by switching around the first endpoint, so that shouldn't be a problem. Is there any way I can force it to establish a new TCP/TLS connection for each subsequent request? Any help would be much appreciated, I have been pulling my hair out with this one!

Why does $T(id_index) return 0 even though t_suspend() is executed successfully?

by mm e

if(t_suspend()) { $dlg_var(start_time) = $timef(%Y/%m/%d %H:%M:%S); xlog("L_NOTICE", "==> processing suspended in transaction [$T(id_index):$T(id_label)] "); } else { xlog("L_ERR", "t_suspend err"); exit; } Sometimes, I get this log==> processing suspended in transaction [0:13614] "，as far as I know, 0 means that the value cannot be obtained. Executing t_continue(tindex, tlabel, rtname) with parameter 0 will fail.by the way, It's a question of probability.
