Hello again :-(
I have a problem with chan_unicall. If I have two simultaneous incoming or
outgoing calls, they sound broken because cpu load goes to 99%. Also with one
call, the cpu load goes to 99%. Seems like device /dev/zap/channel is busy
after 5 or 10 seconds , and chan_unicall does not write to this.
strace with asterisk-1.0.7, zaptel-1.0.7, kernel-2.6.10
===============================

I've been tested different versions of asterisk and unicall, also fix sound
configuration problem, I been trying zaptel modules in kernel 2.4 and 2.6.
