Hi All, I have a situation as follows,
UAC -------------- >[SIP Registra + SIP NAT]- ----------> B2BUA----------------------->UAS IP x.x.x.x IP y.y.y.y IP z.z.z.z Here the UAC registers only with the SIP registra which is again a SIP NAT device for the outside world (towards B2BUA and UAC). I'm clear about the behavious of the SIP NAT and SIP B2BUA when a request is originated from the UAC. But what should be the behavior of B2BUA and the SIP NAT device when an INVITE originated from the server(UAS) side without rport parameter in the Via header? Is it out of the scope of RFC 3581? Your comments are highly appriciated here. Cheers!
