RealPresence Collaboration Server (RMX) 1500/1800/2000/4000 Administrator’s Guide
Polycom®, Inc. 297
5When the application server has completed the pre-conference IVR, the application server routes
the call to a VMR with the collected password appended to the following dial string:
<conf-id>**<password>@mcu-sig-ip. The MCU now has control of the call.
The call is transferred to a conference, which can reside on another MCU.
Guidelines for Using External IVR Services via the MCCF-IVR Package
AVC SIP and TIP protocols are supported in the RealPresence Collaboration Server 1500/2000/4000
only.
MCCF channels support both IPV4 and IPV6.
When the MCCF channel is disconnected, an alarm is displayed and all external IVR files are deleted.
When the MCCF channel is reconnected, the external IVR files are sent to the MCU.
When the Collaboration Server (MCU) is restarted, all existing external IVR files are deleted. When
the MCCF channel connects to the Collaboration Server, the external IVR file are sent to the
Collaboration Server.
H.323 and ISDN protocols are not supported.
In Collaboration Server 1500/2000/4000 only, Video Switching conferences do not support the TIP
protocol
TIP-based conferencing does not support the following features during conferences:
Gathering phase
Skin display
Text messaging using Message Overlay
Site Name display
PCM
Click&View
To play audio messages and display the welcome slide during the participant connection to the
conference via the Virtual Entry Queue, the Media files have to meet the following requirements (as
defined in the Entry Queue IVR Service):
Audio messages: WAV files - PCM, 16 KHz, 16 bit, Mono
Video slides: JPG files - 1920 x 1088 resolution
Configuring the MCU to Support External IVR Services via the MCCF-IVR
The support of External IVR Services via the MCCF-IVR package is enabled by default in the Collaboration
Server (RMX) systems, by the flag ENABLE_MCCF which is set to YES.
However, in Ultra Secure Mode and in secured environments where the External IVR Services via the
MCCF-IVR package is not required and unused ports should be closed, this flag should be set to NO.
To change this flag value from YES to No, you must first add it to the System Configuration. For more details,
see Manually Adding and Deleting System Flags.
Configuring the Entry Queue to Use External IVR Services
The Entry Queue can be configured to place a call in the external IVR-controlled Entry Queue.
