New Revision: 351560

URL: http://svnview.digium.com/svn/asterisk?view=rev&rev=351560
Log:
Eliminates doubling the :port part of SIP Notify Message-Account headers.

This patch prevents the domain string from getting mangled during the initreqprep
step by moving the initialization to before its immediate use.  It also documents
this pitfall for the ast_sockaddr_stringify functions.
