Hi, Cedric!
Are you sure that the flows you do not see are the ones you mentioned?
According to the logs, you do not see the RTP coming from the caller:
RTP stats: 410 in from callee, 0 in from caller
So the problem seems to be not on the private network, but on the public
one. Or there is a reporting bug in RTPProxy :).
What's the user experience for this call? Do any of the participants
hear each other? Also, where are you doing the trace of the RTP?
Best regards,
Răzvan Crainea
