[Asterisk-Users] Any one using the new Digium echocancellation cards

[Richard A. Smith]

David,

Yes we got them and they caused huge problems.  The echo training would
cause the line to mute and you would hear something like a dtmf tone briefly
and then you would be connected and talking again.  This might happen once
or 50 times during a call.  I spoke to Digium and they say there may be a
firmware upgrade coming down the line.  You are right it is a daughter board
placed in the space provided on the existing cards.  We disabled the
daughter board and are basically back to where we started from.

Thanks

I'd also be interested if the module is available as an upgrade to
existing quad boards. It looks rather like the echo canceller is a
daughter board, connected roughly where there's a connector on existing
quad boards...

Have a rather nastry PRI echo problem which so far no fiddling with
settings (tx, rx, taps) has helped with.
