asterisk users - Oct 2006 - bristuff problem?

Hi Kape,

With latest asterisk 1.2.12.1, zaptel 1.2.9.1 and bristuff 0.3.1s after 
a while calls become stuck: either the caller or callee can't hear the 
other party, or heavy static is heard. An asterisk restart fixes it for 
a short while only.

This doesn't happen with our older installs (asterisk 1.2.9, zaptel 
1.2.7, bristuff 0.3.1q).

Are you aware of that problem?

Thanks,
