[Openbts-discuss] No Audio/RTP in incoming calls

[Heiko R. <hr...@py...>]

Hello Community,

after juggling quite a bit with openBTS and it's components, I got it 
mostly working.

Right now, I am hanging on a no-Audio issue:

--> No Audio/RTP on Calls between Handsets.
--> No Audio on incoming calls from outside (through Asterisk) to a Handset.

Upon such a Inter-MS call or on a incoming call, the MS will properly 
ring and the called party can pick up the call.
Instead of any Audio - total silence. After a few seconds, the call get 
dropped (I guess thats some normal silence detection watchdog)

Outgoing calls to and through the Asterisk are working fine inclusive 
two-way Audio.
SMS's are working fine too.

Codecs are all set to 'gsm' on the Asterisk side.

Any idea what could be causing this issue?

Thanks,
Heiko
