Hi,<br> I am facing terrible issue regarding no audio/voice on both sides. I am using g729 codec on two machines and carrier also supports g729 codec. I can see the RTP traffic flowing but there is no audio.<br>Call is going from Server 1 to Server 2. I can see the established SIP channels on Server but still no audio<br>
