[SR-Users] Rtpproxy re-INVITE handling

[Daniel-Constantin Mierla]

Hello,

I could not spot by quick eye checking what could happen there, the best 
is to use the debugger module with cfg_trace parameter set and check the 
execution trace to see what actions of the configuration file are 
executed and be sure the rtpproxy is called or not.

You can post the execution trace here if you need further help with it.

Cheers,
Daniel
