Media Server Control Markup Language (MSCML)

Media Server Control Markup Language (MSCML) is a markup language used in conjunction with SIP to provide advanced conferencing and interactive voice response (IVR) functions. MSCML presents an application-level control model, as opposed to device-level control models. One use of this protocol is for communications between a conference focus and mixer in the IETF SIP Conferencing Framework.
