I have installed many Sangoma T1 cards without hardware echo
cancellation. Never had a problem. I have with Digium though.
Thanks,
Steve

Thanks for the info, Tom. I was thinking along those lines, but just
wanted to get some verification. This is being installed in a fairly
beefy server, and will only be handling ~20 calls at a time or so, so
I don't envision CPU being a problem, but offloading the EC never hurt
anyone.
