asterisk users - Nov 2006 - Sound breaking. Because of Tormenta2 PRI Interface Card or something else

Hi everybody,

I need to know about sound quailty issues from those who have experience
with Tormenta2 PRI Interface. Also how to make it work with new versions of
Asterisk and Zaptel. And also  suggestion if it is a good idea to switch to
some newer card from Sangoma or Digium, or Tormenta should work fine.

I have sound breaking many times a day over the trunks. Server is AMD Athlon
2.4 GHz with 512MB RAM. Serial ports, parallel port and other unnecessary
things on the motherboard are disabled. People in the office don't talk much
with each other over the extensions, so can't say the performance of the
system over the local network, but incoming and outgoing calls start giving
trouble few times a day and people do complain about it.

I was thinking if it was because of the linux kernel, which is
2.4.21-32.ELon CensOS 3, or because of the Tormenta PRI Interface
card. There is no
major use of the Internet in the office. Server is strong enough to handle
calls. And there are never more than 3,4 calls at a time. In fact breaking
of sound can happen when only one person is in the office and only one phone
is being used.

Please help before I start buying new stuff to replace some of the existing
stuff, just to find out that it didn't help anyways.

Thanks

Which Tormenta card exactly? I believe tha there are several companies
that produce Tormenta2-based cards. I know that at least some of them
have some modifications to the tor2 driver, but those modifications
never made it into the main tree (and sometimes not even availble for
download).

That said, I have no experince with either of those cards.

Sounds like a clock slip problem on your PRI interface - what is in your
zaptel.conf ?

Are any of the tormenta2 cards worth purchasing? In what cases would echo
cancellation be needed?
