Thanks Olle. I am calling record_record() on the initial INVITE. In fact, the OK has a Record-Route header:
1.1.1.1 is the endpoint 2.2.2.2 is the kamailio proxy 3.3.3.3 is the backend server SIP/2.0 200 OK Via: SIP/2.0/UDP 1.1.1.1:60077 ;rport=46110;branch=z9hG4bK-d8754z-eb9768c7e3a2d1e7-1---d8754z- Record-Route: <sip:2.2.2.2;lr=on;ftag=db634167;nat=yes> From: <sip:sip7878_s...@edge.domain.com;transport=UDP>;tag=db634167 To: <sip:2155555...@edge.coredial.com;transport=UDP>;tag=as3f9cf263 Call-ID: MzI5YTA3YmRkNzFiZjhhZTRkNTc2OGE1ZTc5ZjdjMmM.
