Hi,

Just wondering if anyone can shed light on a problem I have.

I have an Asterisk box (built from scratch not using trixbox or
anything) running Asterisk 1.4.19, Zaptel 1.4.10 and libpri 1.4.3 on
an IBM x3550.

I purchased a TE220B (the PCIe dual span with the hardware echo
cancelation) for my server back in Feb but only had a chance to
install it this week.

Basically every 2nd call that hits ZAP hangs the server. The first
call either in or out is OK but a 2nd call will hang. I have not been
able to find anything in the logs to would point to what is wrong.

After a bit of testing I removed the hardware echo cancelation module
and everything has worked fine since.

I have googled around a bit and not really found a solution apart from
one post where someone regressed zaptel to 1.4.9
archives.free.net.ph/mes...0130743e.pl.html

Has anyone else experienced similar issues or have any pointers on how
to get it working with the extra module?

Thanks
Jim
