[Asterisk-Users] bad sound ISDN bristuff

[Sjaak Nabuurs]

Hello * users

I've problems with sound quality on zaphfc
Asterisk works fine good sound quality.
If I do "make load" in the bristuf.xx zaphfc dir then sound quality 
drops directly.
Even if I don't load the chan_zap  in the modules.conf

I use this config on more (even old 400Mhz machines) and works correctly.

Looks like an hardware problem but I can't find it.
I don't see any conflics on IRQ or interupts

Using :
Asterisk 1.0.1-BRIstuffed-0.2.0-RC1
ISDN HFC cologne cards

If you have any solutions I would like to hear it.
