The Asterisk.org development team has announced the release of Zaptel
versions 1.2.22 and 1.4.7. These releases contain (among other things)
many bug fixes to the TC400B driver, a bug fix on the wctdm24xxp driver
for users with a VPM150M, as well as numerous improvements and fixes to
the Xorcom driver suite. The much better performing version of fxotune
from 1.4 has now been put into 1.2, so you may wish to rerun this tool
with the new version. As always, please see the respective Changelogs
for additional information.

Both releases are available as a tarball as well as a patch against the
previous release. They are available for download from downloads.digium.com.

Thank you for your support!
