Thanks Adam. My channel banks are pretty old (NEC ND4's) so they don't do anything for echo. I'll have to try tweaking Asterisk.

Here's is my setup:

IAXy  --  broadband network  --  Asterisk  --  TE110P  --  Channel
Bank  --  POTS lines (FXO)

Everything works fine except for the echo at the IAXy.  There is no
echo on the POTS end, so Asterisk is doing a good job of echo
canceling.  Is there any provisioning in the IAXy to do echo
canceling?

If you get echo on the IAXy end, then asterisk is NOT doing it's echo
cancellation function fully. The POTS user will never get echo if you
don't generate any, or their echo cancellation is functioning correctly.

So, you need to tune the echo cancellation at your asterisk box (or
perhaps you can do that in your channel bank?? I dunno how clever those
things are)...

Adam
