Dear Team, I was trying P2P video calling over Public IP with Kamailio. I have used Linphone as client. But my call is connected but no video and audio was there. For reference I am attaching Client and Kamailio logs. Any help will be appreciated.

Computing a time difference when handling a stateless SIP request

by Chaigneau, Nicolas

Hello, New to Kamailio, first post on this ML. I'll probably ask dumb questions, please bear with me :) Here goes the first one. I would like to compute a time difference (with microseconds precision) when handling a stateless SIP request. I looked into the core functions and modules but did not find anything suitable. Before I start implementing this by myself, I'd like to know if there's a simpler way. Thanks for your help! Regards, Nicolas.

TOPOS issue

by David Villasmil

Hello guys, I have this scenario where I have an ongoing transaction. I receive a 180 (non 100rel) with some to_tag, which i forward back to the caller. Then I receive an 183 (100rel) which is forwarded back to the caller, who in turn PRACKs it. It is then that Kamailio (apparently) can't match that transaction internally and replies to the caller (the one PRACKing the 183 (100rel)), with 493 FORBIDDEN. I'm attaching a trace flow. (Kamailio is 10.255.0.1) Anyone ever encountered this? Is this valid and should work? Regards, [image: prack.jpeg] David Villasmil email: david.villasmil.work(a)gmail.com phone: +34669448337

websocket transport protocol in Record-Route header

by Juha Heinanen

No matter if UA uses ws or wss to connect to Kamailio, when K routes INVITE from this UA and record_route() is called, K always adds ;transport=ws parameter to Record-Route URI, for example, Record-Route: <sip:192.168.43.83:7998;transport=ws;r2=on;lr> In this test, Kamailio is listening on that port like this: # SIP over WebSocket listen=tls:192.168.43.83:7998 Why doesn't K in this case add ;transport=wss to the R-R URI? -- Juha

uac_replace_from function

by Ilie Soltanici

Hello, The uac_replace_from seems not to be working properly in the ver 5.4. This is the header I'm trying to change: *From: "Admin" <sip:+123456789@local.ip>;tag=as11428589* by using this function: uac_replace_from("","sip:+123456789@domain.com"); I'm getting the following header: *From: <sip:+123456789@domain.com35316853757>;tag=as11428589* (Double space in the callerid name, and number appended after the domain) Thank you.

A possibility to disable the topology hiding for some destinations.

by Leonid Fainshtein

Hi, The 'topos' module has a very useful "event_route[topos:msg-sending]" option that allows very easily to disable topology hiding for ITSPs that requires the real data in the Contact header field. It looks like the feature is not supported in the 'topoh' module (ref. https://kamailio.org/docs/modules/5.4.x/modules/topoh.html). The available 'event_route[topoh:msg-outgoing]' option requires defining the remote server IP address (or a list of addresses in some cases) that is not always convenient. Is there a chance that "event_route[topoh:msg-sending]" will be added? Best regards, Leonid Fainshtein

Received parameter on Via

by Duarte Rocha

Greetings, When NAT is detected in my Kamailio, the proxy add the parameter "received" to the Via header which includes the source IP. What is the mechanic or function responsible for this behaviour? Does it come from the NATHELPER module? Best Regards,
