The Asterisk.org development team has announced the release of Zaptel
versions 1.2.21 and 1.4.6. These releases contain many bug fixes as well
as performance enhancements (Too many to list here). A couple of major
changes: there is an update to the Octasic API version as well as a
considerable rewrite of the wct4xxp driver. The xpp drivers have been
updated quite a bit as well. There was also a fix for the wctdm24xxp
driver which sometimes reported false power alarms. For further details
as well as the additional changes, see the respective Changelogs.

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!
