Comments:	By: Matt Jordan (mjordan) 2012-10-30 06:25:00.120-0500 Per the Asterisk maintenance timeline page at http://www.asterisk.org/asterisk-versions maintenance (bug) support for the 1.4 and 1.6.x branches has ended. For continued maintenance support please move to the 1.8 branch which is a long term support (LTS) branch. For more information about branch support, please see https://wiki.asterisk.org/wiki/display/AST/Asterisk+Versions.  After testing with Asterisk 1.8, if you find this problem has not been resolved, please open a new issue against Asterisk 1.8. By: Matt Jordan (mjordan) 2012-10-30 06:25:34.863-0500 Additionally, questions asking for information are best asked on either the asterisk-users mailing list or the #asterisk IRC channel.
