[asterisk-commits] mjordan: branch 1.8 r333339 - /branches/1.8/apps/app_voicemail.c

[SVN commits to the Asterisk project]

Author: mjordan
Date: Fri Aug 26 08:36:36 2011
New Revision: 333339

URL: http://svnview.digium.com/svn/asterisk?view=rev&rev=333339
Log:
Bug fixes for voicemail user emailsubject / emailbody.

This code change fixes a few issues with the voicemail user override of 
emailbody and emailsubject, including escaping the strings, potential memory
leaks, and not overriding the voicemail defaults.  Revision 325877 fixed this
for ASTERISK-16795, but did not fix it for ASTERISK-16781.  A subsequent
check-in prevented 325877 from being applied to 10.  This check-in resolves
both issues, and applies the changes to 1.8, 10, and trunk.
