How to restrict Kamailio adding Local VIA header
by panda.paresh＠gmail.com 30 Aug '24

30 Aug '24

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

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 … [View More]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).

apply keepalive to only udp
by James Lipski 30 Aug '24

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("… [View More]

Kamailio integration with REST services
by Sergio Charrua 29 Aug '24

29 Aug '24

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 … [View More]

Limiting Video calls(Volte to video conversion)
by dushy 28 Aug '24

28 Aug '24

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 … [View More]

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

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 … [View More]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.

I have mo media and I must park
by Alexandru Covalschi 27 Aug '24

27 Aug '24

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 … [View More]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 [View Less]

How to invoke RTPengine for re-Invite 200 OK within dialog
by Shah Hussain Khattak 27 Aug '24

27 Aug '24

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 … [View More]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.

push server tcp problem
by Bernd Krueger-Knauber 20 Aug '24

20 Aug '24

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.

The SIP stack uses now an other connection. t_continue fails, because it uses the … [View More]
