[Freeswitch-users] Sangoma D100 usage

[Javier Gallart]

Hello

we got a Sangoma D100 transcoding card, and we like to get it working with
our freeswitch. Freeswitch and the Sangoma card are running on the same
server. The module is properly loaded:

 2010-12-02 07:46:33.393953 [DEBUG] mod_sangoma_codec.c:1102 Reading sangoma

The codecs look also good:
freeswitch at internal> show codecs
codec,Sangoma G723,mod_sangoma_codec
codec,Sangoma G729,mod_sangoma_codec
codec,Sangoma GSM,mod_sangoma_codec
codec,Sangoma PCMA,mod_sangoma_codec
codec,Sangoma PCMU,mod_sangoma_codec

What we don't know is how to actually use the card. We have forced a call
with g729 in the A-leg and g711 in the b-leg but freeswitch doesn't know how
to bridge them. I've tried unsuccessfully this config in the vars.xml:
<X-PRE-PROCESS cmd="set" data="global_codec_prefs=Sangoma G729,Sangoma
PCMU,Sangoma PCMA"/>
<X-PRE-PROCESS cmd="set" data="outbound_codec_prefs=Sangoma PCMU,Sangoma
PCMA"/>

Does anybody has any experience usgin this card?

Thanks

Javier
