Subject: res_stasis: Fix crash when handling a failed blind transfer message.
X-Git-Tag: 12.3.0-rc1~58
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=11858be68cbc2ce36c9d306ed54804d3bfe7b95e;p=thirdparty%2Fasterisk.git

res_stasis: Fix crash when handling a failed blind transfer message.

This changes fixes a crash that occurs when stasis determines if it
should send a message out to an application or not. The code
incorrectly assumed that a bridge snapshot would always be present
when in reality for failure cases it may not be.
