[asterisk-commits] murf: branch 1.4 r67420 - /branches/1.4/pbx/pbx_ael.c

[asterisk-commits at lists.digium.com]

Author: murf
Date: Tue Jun  5 13:17:28 2007
New Revision: 67420

URL: http://svn.digium.com/view/asterisk?view=rev&rev=67420
Log:
Added code to automatically add a default case to switches that don't have one. In some cases, rather than fall thru, it results in a goto with -1 result, which terminates the extension; a sort of dialplan seqfault, sort of. This was required to fix bug reported in 9881
