[Asterisk-Users] Generic X100P's

[Ken Alker]

Steve -

When you recommend a channel bank to eliminate echo, are you assuming use 
of a T-1 with the channel bank?  I'm curious because I bought a used CAC 
ADIT600 with 24 FXO lines and 8 FXS.  I'm terminating my 8 POTs lines into 
8 of the FXO lines on the ADIT600 as I don't have a T-1.  The ADIT600 is 
connected to my Asterisk box via a T100P.  I'm using Cisco 7960 IP phones. 
I'm having local echo problems (customer calling in can't hear the echo but 
my agents hear it).  Thus, I'm using a channel bank and I've got the 
problem.
