Thank's Daniel,

I need process cancel requests to delete sessions on rtp proxy... In a call forking, when I need forking to multiple destinations on different network segments, requiring different rtpproxy parameters, I use the “extra_id_pv” and "b" parameter in the rtpproxy_offer() function to created a session RTP to each branch of calling in rtp proxy. When one of branch answer the call, I want delete the other(s) session(s) on rtp proxy (unforce_rtp_proxy()) using the CANCEL SIP message to do this, but I can't get handle it in configuration file... I am wrong trying use the CANCEL message to delete session rtp? I will try onsend_route to handle...

Best Regards

Hello,

why do you need to process cancel requests? They have special routing requirements related to associated invite and sent from tm directly. The event route is for the requests sent by modules via tm.

Haven't tried, but maybe onsend_route will capture it.

Cheers, Daniel

Hi All,

in a call forking, after one branch answer the call (200 OK reply), a CANCEL SIP message has been sending to other/another branch(es) and I need to process this/these cancellations in configuration file. After reading some documentations, I discovered there is event_route[tm:local-request] block, which is executed when tm generates internally and sends a SIP request, Such cases are:

SIP messages sent by msilo module SIP messages sent by presence server SIP messages sent by dialog module SIP messages sent via MI or CTL interfaces

I didn't understand very well this cases, so I insert event_route block in my kamailio.cfg but neither CANCEL SIP message or other requests generated by tm module was handled by event_route. I must be using wrong concept to handle this CANCEL SIP message, it's possible handle this messages in configuration file?

Best Regards

Hi Daniel,

Sure Daniel, I can process 487 on onreply route... I was trying to handle 487 in failure_route block, I didn't know it can be processed in onreply_route!

I know that rtpproxy destroys the session by itself in short time it is not confirmed, but I'm trying to force it the most amount of possible cases.

Now, my final problem (I hope) is destroy the rtp session when receive the BYE message to finish a forking call. I have to add “extra_id_pv” and use "b" parameter to get destroy the session on rtpproxy, but I don't know if exist somehow to discover if the BYE belongs a forking call context. I tryed use $branch variable but without success...

Best Regards

maybe you can do it onreply route, when the invite is replied with 487.

Anyhow, rtpproxy destroys the session by itself in short time it is not confirmed.

Thank you for attention and help Daniel...

for while I will leave the rtpproxy destroy the session by itself in short time it is not confirmed or by timeout if didn't received the delete of session. I think be better to start a new discussion thread about the new problem too...

failure route is executed when all branches fail, on reply route is executed for each reply received.

I know that rtpproxy destroys the session by itself in short time it is not confirmed, but I'm trying to force it the most amount of possible cases.

I haven't worked with this extensions, maybe you get proper details from the appropriate developers. But might be better to start a new discussion thread with appropriate subject so it is spotted -- at least for me it is relevant to see proper subject, because if it is a discussions where I am not part which diverts to different topic where I could help, I don't read always.

Cheers, Daniel
