Hi All, Using OpenSIPs 3.0.3
I'm dealing with a client device with a faulty network, they are using a softphone WebRTC client and the TCP connections disappear sporadically. When the media server issues a RE-INVITE session timer OpenSIPs discovers the closed TCP connection and returns 477 to the media server. In this case the media server is FreeSWITCH which promptly ignores the non-standard session timer response and the call hangs. I want to close the call immediately in this situation as there is no way I can see to reestablish the connection. The call is typically bridged on the media server so the other call leg is left dangling indefinitely so I need to find a way to kill the session. Reading RFC4028 <https://tools.ietf.org/html/rfc4028#section-10> the only response codes that should trigger a BYE are 408/481 so my aim is to intercept the 477 and alter it. Unfortunately I have been unable to intercept it within my OpenSIPs config as the messages don't hit failure_route or similar. Am I missing a trick? Is there somewhere where these can be intercepted or should I be looking into a solution on the media server instead?
