[Asterisk-Users] TDM2400P driver change

[Rich Adamson]

According to the posting on the -cvs list, there was a small change
to the wctdm2400 driver (or whatever the correct name is). Therefore
you should be able to download the zaptel source, compile, and install.

This assumes you're running a fairly recent version of asterisk, which
you probably are if you already have that driver.

If I recall recorrectly, the change was a one line item. You could
probably find that change, edit the one line and recompile.

> 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.
