MSCML Interface

Media Server Control Markup Language (MSCML), according to IETF RFC 5022 is a
protocol used in conjunction with SIP to provide advanced announcements handling.
MSCML is implemented by adding an XML body to existing SIP INFO messages. Only a
single message body (containing a single request or response) is allowed per message.
The device supports all the Interactive Voice Response (IVR) requirements for playing
announcements, collecting digits, and recording (Play, PlayCollect, and PlayRecord).
Note:
The following figure illustrates standard MSCML application architecture:
The architecture comprises the following components:

Device: Operating independently, the device controls and allocates its processing
resources to match each application's requirements. Its primary role is to handle
requests from the Application server for playing announcements and collecting digits.

Application Server: An application platform that controls the call signaling. It
interfaces with the device using MSCML. It instructs the media server to play
announcements, collect digits and record voice streams.

Remote Storage: An HTTP server that contains less-frequently used voice prompts
for playback and to which voice stream recording is performed.

IP Phones / MediaPack: Client applications.
Version 6.6
MSCML is only supported on devices operating with 128-MByte RAM size.
