No sound or poor sound quality.

Bad file format.

Ensure that the file formats are compatible. A good announcement file format must have the following parameters:

• 8-Kbps sample rate

• 8-bit resolution (bits per sample)

• A-law or μ-Law companding format

• Mono (channels = 1)

Incorrect companding mode.

Ensure that the same companding mode is administered on page 1 of the Location Parameters screen (type change location- parameters) for both environments.

An announcement does not play.

If a working VAL announcement file is deleted, the next attempt to play the announcement fails, and the system adds a software event to the Denial Events Log.

View the Denial Events log to determine if the announcement was deleted. If the announcement was deleted, restore or rerecord the announcement.

The system displays error code E28 when you attempt to restore announcements.

An integrated announcement source is not installed in the system.

Install an integrated announcement source.

The system displays error code E31 when you attempt to restore announcements.

A call is connected to the announcement on the announcement source and the port is busy.

Wait for the call to disconnect, and try to restore announcements again. If the system has an abnormal shutdown, or if there is a processor interchange during the restore announcements process, the restore process fails. There is no valid announcement on the announcement source. Repeat the process when the system is operating properly.
