VMSC - VMD - Audio Encoding Dialog Box

This topic describes how to use the Audio Encoding dialog box to configure audio encoding formats.

Audio encoding formats determine the way in which audio is recorded on every Messaging Application Server (MAS) in the voice mail domain. This, in turn, determines the format of voice messages sent using the Telephone User Interface (TUI) and desktop clients. The client applications are then automatically configured to use the selected audio encoding format.

You can use the Audio Encoding dialog box to set up the default audio encoding format and enable support for teletypewriter (TTY) devices in the voice mail domain.You can configure text to add to all voice messages, explaining what the recipient must do in order to listen to the message. This text is only seen by recipients who have not installed Avaya Modular Messaging.


Notes: After setting the audio encoding format, you must stop and restart the MM Messaging Application Server service. For this procedure, see MAS - Stopping and Restarting Modular Messaging Services. For detailed information on audio recording formats, see the Avaya Modular Messaging Concepts and Planning Guide.

Launching the Screen

In the Voice Mail System Configuration window, click the voice mail domain.

Double-click Audio Encoding. The system displays the Audio Encoding dialog box for the selected VMD, with the Audio Encoding tab active.

Configuring the Screen Controls

Default Audio Encoding Format Select the audio encoding format you require.

Microsoft GSM 6.10 (the default).

G.711 �-law (mu-law).

G.711 A-law.

Note: Ensure that the form of G.711 encoding matches that of the switch. In general, �-law (mu-law) is used in North America and Japan, and A-law is used in Europe. If your choice of encoding scheme does not match the switch, then audio will sound garbled.

Enable system for devices used by people who are deaf or hard of hearing (TTY) Select to enable support for teletypewriter devices in the voice mail domain. For instance:

The system plays Hold (HD) tones, when a call is first answered.

The system plays Go Ahead (GA) tones, when the recording starts.

Note: This setting also forces audio encoding to G.711.

Voice Mail Text Body Enter the text to add to all voice messages as a text body, explaining what the recipient must do in order to listen to the message.
