Hello,

I couldn't spot anything wring with the INVITE. What phone/application is the receiving party? Can you get any log messages from it?

As I can spot based on Record route headers, there is another proxy in between IPv4-IPv6 gateway and the receiving party -- the intermediary proxy has no problem with the packet.

Cheers,
Daniel
