New Revision: 370126

URL: http://svnview.digium.com/svn/asterisk?view=rev&rev=370126
Log:
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.
