Hello,

Thank you for your support of Digium and Asterisk.

Yesterday, we identified a problem with the driver for the TDM2400P card
when used with FXO port modules.  The X400M was producing (and
expecting) the audio signal at an abnormally high level, which negatively
impacted the performance of the echo cancelers, both hardware and software.
It also resulted in unusual audio artifacts when the actual signal was
already at a high level.

The driver in our Subversion repositories of Zaptel (both 'trunk' and
'branches/1.2') has been modified to properly initialize the FXO ports to
alleviate this problem.  We encourage all owners of TDM2400P cards with FXO
ports to update their driver as soon as possible, especially if they are
experiencing audio quality and/or echo issues on the FXO ports.  This
updated driver will be part of the Zaptel 1.2.2 release as well, if you wish
to wait for a tarball release.

Thank you again for supporting Digium and Asterisk!
