[asterisk-users] Randomly half-voice at sip/zap

[Péter Tóth]

Hi!

I have a very strange question. I'm using trixbox with Asterisk
1.2.23-BRIstuffed-0.3.0-PRE-1y-j.

I configured and installed the HFC ISDN card with a script, as here:

http://www.trixbox.org/forums/trixbox-forums/help/how-install-hfc-card-trixbox

Now i have 6 SIP hardphone, and softphone, using 1 SIP trunk to call
out the world, and 1 ZAP ISDN trunk to receive calls from the world.
The incoming route directed to a ring group.

Sometimes the incoming calls - from pstn - are not, the caller do not
hear any voice from us. When i call out on the sip line, it happens
indirectly, so i can't hear nothing from the other side, especially
when i call my sip telco provider. (10 try, 2 wrong) If they're
calling me, everything is ok!

Please help me!

Thanks in advance!
