Problem with D110PG noise for caller

You need that Asterisk server is connected to T1/Vox line? I cant connect asterisk to line T1/Vox becasue I am using this line with us old PBX.

I can give you a ssh account to this server but it doesnt have conection to line T1 (PTSN)
It works 4U?

I put the card in other machine and it works fine.

you have to connect the T1 line to the card, otherwise I could not diagnose.

I think it is a s/w issue, since one way audio is correct. you can try to place a inbound call from t1 to listen to the voice menu, and see if the caller can get correct voice.

OK.!
I did this part, inbound call. The agent get correct voice but the person that do the call just get noise and the voice.
I installed this card in other hardware , no Dell, and I got everything fine as should be.
I will connect the server to T1 and I send the password.
There is any issue with dell.???

not sure issue with the dell, what linux installed?

Linux Lenny/Debian
Kernel told you the kernel above

I need know the version of kernel... and type of cpu
