From fdd39eae5850e699aac2609d5baf41e0945929a0 Mon Sep 17 00:00:00 2001 From: Joshua Colp Date: Mon, 16 Jul 2012 19:14:29 +0000 Subject: [PATCH] Fix an issue where a service discovery request could crash Asterisk. A server sending a service discovery request to us may or may not put a from attribute in the message. If the from attribute is present use it in the to attribute for the result. If the from attribute is not present do not add a to attribute.
