External IVR Service Control
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.
For more information, see Using External IVR Services via the MCCF-IVR Package.
IVR Services Support with TIP Protocol
From Version 8.1, Conference IVR and Entry Queue IVR Services are supported with AVC TIP protocol in
conferences that include both TIP-enabled and non-TIP-enabled endpoints. TIP-enabled endpoints can be
moved from the Entry Queue to the destination conference if the TIP Compatibility Modes settings in the
Profile are identical for both conferencing entities (it is recommended to use the same Profile for both
entities).
The IVR services can be enabled for all TIP Compatibility Modes:
Video only
Video and Content
Prefer TIP
IVR media files, WAV for voice messages and JPG for video slides, are all stored on the RealPresence
Collaboration Server (RMX).

Guidelines for TIP Support with IVR Services

AVC SIP and TIP protocols are supported on the RealPresence Collaboration Server
1500/2000/4000 only.
IVR default audio files are enabled for all TIP Compatibility Modes.
Only Polycom default Welcome slides are available. Custom Welcome slides are not supported.
TIP-enabled endpoints can send DTMF digits to MCU.
In an mixed TIP environment, there is no support for content in cascaded conferences. Additionally,
Legacy and Lync endpoints cannot view content.
