Others have also observed consistent echo problems with the
mec2 and kb1 cancellers when installed against a channel bank. Likely this has
been addressed by the patches incorporated into the new mg2 derivative which
attempt to deal more correctly with really wide ranging signal levels. It would
be helpful if you and/or others in the same situation could take a moment
to evaluate the performance of http://bugs.digium.com/view.php?id=5520 against your
current solutions and add your feedback.

Just a point of reference for others, we had a lot of echo on an Adtran Channel Bank connected to a T100P.

Subject: Re: [Asterisk-Users] Echo Canceller question- is there aviablesolution?
The end poitns were all Polycom Ip500's on a local lan connecting to *.
We couldn't solve the echo with any software settings and installed a Tellabs Echo Can shelf 255D i believe with 64ms echo cans, that resolved the problem completely.
No more yelling from the secretaries :)
I'm happy.
