[SR-Users] Rtpproxy - IPv4/v6 Translation and earlier removing of session

[Daniel-Constantin Mierla]

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
