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!
