Subject: Fix execution of 'i' extension due to uninitialized variable.
X-Git-Tag: 10.11.0-rc1~41
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=71ed8c3343eab2892c51af1cd73d1f891cc714e8;p=thirdparty%2Fasterisk.git

Fix execution of 'i' extension due to uninitialized variable.

The fix for ASTERISK-18243 added code that could potentially use
dst_exten[] uninitialized.  As a result the 'i' exten may not be executed
when it should.

(closes issue ASTERISK-20455)
