Hi Asterisk Users,

i have a bristuffed-0.2.0-RC8q Asterisk 1.0.9 System running on a Debian 
3.1. With a quadbri card installad, wich is running on the bristuff drivers.
Everything seems to be fine so far.
but now i wanted to use the g.729A Codec. I bought 5 licences and 
installed them:
asterisk3*CLI> show g729
0/0 encoders/decoders of 5 licensed channels are currently in use

 When i do sip to sip calls, everything is working fine (from a snom 190 
wich is running with that codec to a sip phone with g.711a), asterisk is 
translating correct.
the output on the CLI is:
asterisk3*CLI> show g729
1/0 encoders/decoders of 5 licensed channels are currently in use

But if i try to call a zap channel from that sip phone (snom 190) wich 
runs that g729 Codec, i don´t hear anything on the ISDN Phone. the 
output on the CLI:
asterisk3*CLI> show g729
1/1 encoders/decoders of 5 licensed channels are currently in use

Here is the output of the show channel command for the SIP Channel and 
the ZAP Channel:

asterisk3*CLI> show channel SIP/71-d293

I don´t know what i can do on this problem and would be pleased to get 
some help.

Thank you very much!
