[OpenSIPS-Users] No voice, while using 3G ( OpenSIPS & RTPProxy on AWS )

[Răzvan Crainea]

Hi, Maksim!

You should trace the traffic on the opensips machine and check whether 
opensips sends the correct messages (SDP body) to each user agent.
Next, you should trace on the RTPProxy to see if you get media stream 
from both ends.

Best regards,
