[Freeswitch-users] GSM gateway to Freeswitch audio problem

Wed Jun 8 19:41:00 MSD 2016

I have captured the packets at both the endpoints:

Freeswitch does not receive RTP packets, logs:

where, when I make call from a registered SIP account configured at a
softphone, I clearly hear sound form ivr-demo sound.

GSM VOIP Gateway is sending RTP packets:

Codecs settings at both the ends is PCMA and PCMU only

Thanks,
Deepika
