asterisk users - Oct 2005 - FC4 + ztdummy + timming + trunking

Hi,

Using a FC4 system without a digium card to centralize a few other systems
with digium cards makes sound to break when zaptel module is loaded.  Even
if ztdummy is present.

If i unload zaptel module, it works fine, but when i try to do a call with
trunking, asterisk does not even answer.

On those FC4 that has digium cards, everything works fine (trunking, timing,
everything).  So it makes me think that is something about RTC or timer
handled by zaptel module.

On a 2.4.x kernel, it works fine when i load the usb module as said in many
support pages.  But kernels 2.6.x should handle timing without the USB
module i guess.

any hint or idea on how to fix this problem?

Regards
