[OpenSER-Users] proxy1(client)-->Openser-->proxy2(supplier)

[Dan-Cristian Bogos]

Hi there Kaeman,

first of all in the case of checking calls to registered behind nat
users, you should check branch flags and not global ones.

Regarding your question, if you have a problem, please send us the
logs if SIP Messages (ngrep -t -W byline port 5060), the proper
description and the configuration used.

Cheers,
DanB
