Embedded Music on Hold
Embedded Music on Hold is provided by an audio file downloaded in the controller. The audio file must be in the following format:
WAV, A-law or m-law (G.711), 8 kHz, 8-bit, mono.
See System Audio Files Update for the maximum size of the audio files.
Tip: When extracting a file from a CD (for a example, from your corporate Music on Hold CD) using a "CD ripper" application, choose a sampling rate as close as possible to 8 kHz. This should help prevent audio distortion introduced when converting a WAV file from a high sampling rate to a low sampling rate.
When an audio file is downloaded, its audio amplitude is normalized by the controller to ensure uniform sound level and compliance with telecommunications regulations.
You can download audio files to a single controller using the System Audio Files Update form, or to multiple nodes using Enterprise Manager (see your Mitel dealer for information on Enterprise Manager).
