[SR-Users] rtpengine with rejected re-invites to new RTP ports

Hello, Given the following scenario with Kamailio and rtpengine in the middle: - call establishes with G.711 RTP - b-leg re-invites to T.38, indicating a different port number then he is using for G.711 - a-leg refuses the re-invite with a 488 - call continues using G.711 on original port numbers as if re-invite never happened Will Kamailio and rtpengine handle it? Today I have a functional configuration with rtpproxy on another SIP proxy. It handles every scenario I have tried except this one. rtpproxy sees the new ports in the re-invite and adjusts its session accordingly. If the re-invite is rejected, the old media ports are no longer valid through rtpproxy, and the call fails. Is there an approach I can take with Kamailio and rtpengine to allow this scenario to succeed? Regards, Jeff
