Polycom, Inc.
The administrator can enable an audio message that informs the participant of the lack
of Video Resources in the RMX and that he/she is being connected as Audio Only . The
message states: All video resources are currently in use. Connecting using audio only .
The following guidelines apply:
— The IVR message applies to video participants only. Audio Only participants will
not receive the message.
— Only H .323 and SIP participants receive the audio message.
— Downgrade to Audio Only is not supported for undefined ISDN dial in participants.
These participants are disconnected if there is a lack of Video Resources .
— The audio message is the first message after the call is connected, preceding all
other IVR messages.
— The message is called No Video Resources-Audio Only and the message file ( .wav ) is
called No video resources audio only.wav .
— The audio message must be added to the Conference and Entry Queue IVR Services
separately.
— The IVR message can be enabled/disabled by the administrator using the
ENABLE_ NO_VIDEO_RESOURCES_ AUDIO_ONLY_MESSAGE System Flag
in system.cfg .
Possible values: YES / NO, default: YES
If you wish to modify the flag value, the flag must be added to the System Configuration
file. For more information see the " Modifying System Flags” on page 21-1 .
