Here is a "ngrep-sip br" attached 192.168.10.1 is the OpenSER 1.3.0 server 192.168.10.10 is the SNOM SIP phone 192.168.20.1 is the external PBX (Alcatel 4400 R9.0)
As far as I can see, OpenSER get's the ACK from the phone, fails to follow the contact field and tries to send the ACK to itself.

I may need to get deeper debug settings here - but it's a
production
system so I can't really experiment much. (We've solve the
problem by
routing via an ISDN gateway at the moment, which is rather
unfortunate
:D)
Can I have a ngrep capture?
