New Revision: 405266
URL: http://svnview.digium.com/svn/asterisk?view=rev&rev=405266
Log:
res_pjsip_messaging: potential for field values in from/to headers to be missing
Added in ability to specify display name format ("name" <sip:name at ipaddr:port>)
for a given URI and made sure it was fully propagated to the outgoing message.
Also made it so outoing messages in res_pjsip always send as "sip:".
(closes issue ASTERISK-22924)
