Author: russell
Date: Wed Jun  1 16:31:40 2011
New Revision: 321546

URL: http://svnview.digium.com/svn/asterisk?view=rev&rev=321546
Log:
Support routing text messages outside of a call.

Asterisk now has protocol independent support for processing text messages
outside of a call.  Messages are routed through the Asterisk dialplan.
SIP MESSAGE and XMPP are currently supported.  There are options in sip.conf
and jabber.conf that enable these features.

There is a new application, MessageSend().  There are two new functions,
MESSAGE() and MESSAGE_DATA().  Documentation will be available on
the project wiki, wiki.asterisk.org.

Thanks to Terry Wilson for the assistance with development and to David Vossel
for helping with some additional testing.

+ * Asterisk now has protocol independent support for processing text messages
+   outside of a call.  Messages are routed through the Asterisk dialplan.
+   SIP MESSAGE and XMPP are currently supported.  There are options in
+   jabber.conf and sip.conf to allow enabling these features.
+     -> jabber.conf: see the "sendtodialplan" and "context" options.
+     -> sip.conf: see the "accept_outofcall_message" and "auth_message_requests"
+        options.
+   The MESSAGE() dialplan function and MessageSend() application have been
+   added to go along with this functionality.  More detailed usage information
+   can be found on the Asterisk wiki (http://wiki.asterisk.org/).
