depends on the source of your echo
if its the motherboard latency issue  then no external device will help
but assuming it external to the b check the external t1 hardware echo can's
I use a older tellab 2572 64ms tail inline between the t100 & the ta 750
with all asterisk echo related settings OFF
I have seen other echo can reported to work
( the telllab 257? can be had for 50/card but the chassis are hard to come
by
you nned to do leg work with the after market used online suppliers)
