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!
