asterisk users - Dec 2005 - TDM2400P driver change

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!
