[SR-Users] rtpproxy and timeout notification

Hello all, I see the new timeout notification feature from the rtpproxy when no voice traffic is detected. I have 2 questions regarding this timeout notification: 1) When a timeout is detected and kamailio send the BYE is that possible to manipulate the BYE before he is sent to add maybe an extra header that indicate that the call was stopped due to a timeout issue ? 2) If a user put the call on hold (with a=recvonly or maybe old way IP=0.0.0.0.0) what will happens (the music on hold is not generated by rtpproxy but by another server) ? he will detect this as a timeout ? Is that possible to indicate to rtpproxy that for a moment stream will be only in one way ? Best regards Laurent
