Hi all,
We have a BRI installation who is experiencing constant echo with the
Digium b410p and mISDN.
I have adjusted gains, and originally thought that the desktop phones
were at fault, although we experience the same problem when a call is
bridged out to an external number.
I've tried it with 128 taps (the default and I believe the supported
taps for the onboard hardware echo cancellation) and with 256 taps
(which I assume is using the software echo cancellation).
Obviously there is no fxotune for mISDN, no oslec (well there is, but
the patches to enable this seem to come with significant delay), and no
HPEC so I'm at a bit of a loss as to what to do.
I've tried multiple versions of chan_misdn, mISDN, mISDNuser all to no
avail.
Does anyone have any ideas?

Matt Riddell
