If it is Near Side echo (I.E. on the 7960 side) try telling your people to 
lower the handset volume to 50% and see if it goes away. I've found that 
the 7960's have very sensitive mics in the handset and if the earpiece 
volume is too high, the mic will pick it up and it shows up as a really 
annoying echo artifact that will drive you nuts. Nothing you will do on 
the Asterisk side will take care of it.

I've not had any issues w/ my TE100P and TE405P cards using X/O, Easton 
and Broadwing PRIs.
