Hi everybody, I'm working on UAS side. I've noticed that if I register a module at PJSIP_MOD_PRIORITY_APPLICATION level, when I receive an INVITE retransmission and the invite transaction is in the "Proceeding" State, my "on_rx_request" function is not invoked. This is right, RFC3261 says that in "Proceeding" State the INVITE request is not passed to TU. But it also says that the most recent provisional response that was received from the TU MUST be passed to the transport layer for retransmission. To do that, I've thought to register a module at PJSIP_MOD_PRIORITY_TSX_LAYER-1 level (which is the last level informed about retransmission) and handle the provisonal response retransmission there. Do you think this is the right way? Any better suggestions? Thanks so much! Giorgio
