asterisk users - Aug 2004 - iax->asterisk->capi isdn; crackle overlay after about 1 minute

Hello,

asterisk works fine altogether. But there is a problem with
iax->asterisk->capi-connections. After about one minute of conversation
over
this channel a crackle overlays the voice. I dont mean interrupts caused by
too slow data connections. You can hear the voice continuously any longer.
The crickle is louder than the voice.

System:
AVM Fritz Card DSL with Capi ISDN interface. Capi kernel module from AVM
Kernel 2.6, I tried different ones from 2.6.4 to 2.6.7
IAX-Client: IaxComm on a separate Windows-machine, connected via 100MBit Lan
to the Linux-server

I tried different asterisk versions, from Debian testing, unstable to
asterisk CVS and different chan-capi modules from version 3.01 to 3.04b, the
newest.

Other Capi-applications like capisuite and isdn-log work fine, too.

Does anyone know this problem and could give help?

Thanks, Christian Deipenbrock
