[SR-Users] Problem with rtpproxy and rtpproxy_manage()

[Daniel-Constantin Mierla]

Hello,

you should provide a ngrep output of such call (incoming invite to the 
forwarded ack for 200ok), we can check the sdp.

On the other hand, I didn't have good experiences with rtpproxy 
application from git head, can you try with 1.2.1?

Cheers,
Daniel
