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.

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
