Hi Morten,

You would have the same problem even if you were not using B2BUA.

It seems like you have an equipment between the end user and OpenSIPS that adds that Record-Route header with a private IP, and also a Via header.

Via: SIP/2.0/TCP;branch=z9hG4bK34022d4918236c6b79e8bc8e6,
Record-Route: <sip:;lr;transport=tcp>

So your problem seems like a setup problem on that equipment.
