Using External IVR Services via the MCCF-IVR Package
IVR Services can be controlled externally from an application server supporting the MCCF-
IVR (Media Control Channel Framework-Interactive Voice Response) package. The external
IVR service is currently being implemented with the integration of the Polycom
RealPresence Virtualization Manager (DMA) as the application server. When the
application server is deployed in the enterprise environment and the Polycom RealPresence
Collaboration Server (MCU) is deployed as a media server, the external IVR service can be
used to play audio messages, display slides, and collect DTMF input from the participant.
The external IVR service is managed by the application server at the pre-conference phase
when the participant is placed into a special external IVR-controlled Entry Queue in the
Collaboration Server (MCU), collecting information before connecting to the conference.
The external IVR-controlled Entry Queue plays recorded voice messages or sends video
slides such as splash screens to the participant and collects DTMF input from the participant
such as conference ID and conference password for various functions.
IVR media files, WAV for voice messages and JPG for video slides, are stored on the
application server. In order to provide external IVR control, a TCP-based MCCF channel is
created between the application server and the media server. Because of real-time
considerations, when the MCCF channel is established, the application server notifies the
media server about the media files. The media server downloads the media files. The media
server is notified by the application server when to download new or updated media files.
When the call has completed the pre-conference phase in the external IVR-controlled Entry
Queue, the application server disconnects the call from the Entry Queue and routes the call
to an ongoing conference or creates a new VMR.
Guidelines
