Comments:	By: Olle Johansson (oej) 2008-07-05 13:17:57 All new functionality needs to be developed against trunk, not 1.4. Thanks. By: Olle Johansson (oej) 2008-07-05 13:19:09 The RFC 2833 doesn't mention sending anything over SIP INFO. Who implements this and why? By: Alisher (licedey) 2008-07-07 11:10:04 These ip phones implements it: http://www.dasannetworks.com/english/solutions/html/solutions_main.asp?check=group https://www.samsung070.com/images/business/phone/img_general_SMT-i3010.gif Also there is a company Xener systems that supplies softswitches major telecom and ISP in Korea works supports it. http://www.xener.com/servlet/DownloadSV?p_filepath=/test_board/Xener%20Introduction_(English)[1195816776446].pdf By: Leif Madsen (lmadsen) 2008-12-05 08:29:14.000-0600 If someone wants to take this up and move it along, then please have a bug marshall on #asterisk-bugs on the IRC network irc.freenode.net have it reopened. However, since this is a feature request without a patch (with an accepted license) I'm going to suspend this for now.
