Abstract
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.
