[Freeswitch-users] GSM gateway to Freeswitch audio problem

[Benjamin Cropley]

Deepika,

Have you tried doing packet capture and looking at the RTP data to be sure
audio is 100% being transmitted between the two endpoints?

By that I mean..

- Do a packet capture on FreeSWITCH server and check RTP is sent and
received
- Do the same thing, but from the GSM gateway (if possible) and check the
same.

p.s. your log file is truncated on the longer lines :(
