Editing VoiceXML (section)

=== MSML, MSCML, MediaCTRL ===
In [[media server]] applications, it is often necessary for several call legs to interact with each other, for example in a multi-party conference.  Some deficiencies were identified in VoiceXML for this application and so companies designed specific scripting languages to deal with this environment.  The [[MSML|Media Server Markup Language]] (MSML) was Convedia's solution, and [[MSCML|Media Server Control Markup Language]] (MSCML) was Snowshore's solution. Snowshore is now owned by Dialogic and Convedia is now owned by Radisys.  These languages also contain 'hooks' so that external scripts (like VoiceXML) can run on call legs where [[Interactive voice response|IVR]] functionality is required.

There was an IETF working group called ''mediactrl'' ("media control") that was working on a successor for these scripting systems, which it is hoped will progress to an open and widely adopted standard.<ref>{{cite web|url=http://www.ietf.org/html.charters/mediactrl-charter.html |title=Media Server Control (mediactrl) |access-date=2009-01-18 |url-status=dead |archive-url=https://web.archive.org/web/20090130032347/http://www.ietf.org/html.charters/mediactrl-charter.html |archive-date=2009-01-30 }}</ref> The mediactrl working group concluded in 2013.<ref>{{Cite web|url=https://datatracker.ietf.org/wg/mediactrl/history/|title = Media Server Control (Mediactrl) -}}</ref>
