[Freeswitch-users] gsm file record/playback

Fri Jun 6 11:29:01 PDT 2008

It is not inbound codec issue. When I enable only GSM codec in my x-lite I
can see that GSM is negotiated inbound codec. Even in that case recording in
gsm is not working. However recording in uncompressed PCM wav format is
working properly.
I have the same behaviour with rc3 and some snapshot release after that, but
for the sake of this test I have default Freeswitch 1.0 configuration on the
separate box.

Could it be that compressed gsm encoded recordings are not supported
anymore?

Regards,

Miroslav
