asterisk users - Oct 2008 - Asterisk with SC440 Dell(Big Problem)

I have a Dell SC440 with Centos and Asterisk 1.4.21 and a card openvox D110PG,
T1, when a person calling from the PTSN will listen to them but then begins to
distort the voice I heard that name. I probe the card in another computer and it
works perfectly. Anyone has any idea or help. I'm going crazy with this
problem. Install Debian on this server and the same thing happened to me.
I bought this server and now it doesnt work with asterisk.
I will appreciate if somebody has any cluee or idea about this.

If anybody has this server i'd like to know everything about your config. 
TIA

This symptom is not clear to me at all. Calls from PSTN to where,
exactly? What devices? Directly to Asterisk (voicemail, echo test)? To 
a SIP device? What about calls that don't go through the card?

What do you see on zttest -v  ?

What version of zaptel do you use?

Both Centos and Debian Etch have a kernel based on 2.6.18 . OTOH, latest
versions of Etch also include kernels based on 2.6.24 (the etchanahalf
kernel, if I spell that correctly). Maybe also try that?
