Hello all, We are trying to use Freeswitch as a SBC in conjunction with Opensips. The call flow looks like this User UA -> Opensips -> ITSP | | \/ /\ Freeswitch Opensips acts as a registrar and select the outbound route and listens on X.X.X.X:5060. Freeswitch is a B2BUA and signaling server with media and listens on X.X.X.X:5070. Basically a user sends an INVITE and immediately following auth, Opensips forwards to Freeswitch which sends a new call back to opensips which is then routed to our ITSPs. With FS not listening on the default port, we get a received in the Via: message. Via: SIP/2.0/UDP X.X.X.X:5070;received=X.X.X.X;rport=5070;branch=z9hG4bKpU7KvSaeKSc5D Is there any way to remove the received header? Thanks, Spencer
