Configuring message waiting indicator (MWI)

To configure the message waiting indicator (MWI) for a voice mail domain, use the Message Waiting Indicator - Voice Mail Domain dialog box.

MWI allows subscribers to be alerted when messages meeting specified criteria arrive in their mailbox. Subscribers are alerted either by a lamp indicator on their telephone, or an audible tone (stutter dial-tone) when they pick up the receiver. The indicator is cleared when the message is opened, or saved or deleted using the TUI. Subscribers can set up mailbox rules for using MWI in Subscriber Options.


Notes: If, for any reason, you find it necessary to re-install the MWI software after the initial system installation, you must first stop all Avaya Modular Messaging (MM) services on the MAS before installing it. Remember to restart the MM services when the software installation is complete. For the procedures to stop and restart the MM services, see Stopping and (re)starting Modular Messaging (MM) services. The following procedure configures the MWI feature for the entire system. For individual mailboxes, enable MWI using the Subscriber Administration tool.

To display the Message Waiting Indicator - Voice Mail Domain dialog box:

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

If you have more than one voice mail domain, you may need to expand the tree hierarchy to find the one you want.

Double-click Message Waiting Indicator.

The system displays the Message Waiting Indicator - Voice Mail Domain dialog box, which has only one tab, the General tab.

To configure MWI properties, configure the following fields:

Enable Message Waiting Indicator (MWI) To enable MWI for the system, select this check box. By default, this check box is cleared (MWI is not enabled).


Notes: If your system has more than one MAS, you should enable MWI on only one MAS. The following MWI configuration fields appear only when MWI is enabled. For more information about enabling MWI, see Enabling MWI for subscribers.

MAS MWI server Enter the name of the machine on which the MWI service is installed. To locate the server by browsing, click the browse button

Limit requests Select if you want to restrict the number of MWI requests made per minute. By default, this check box is cleared.

Maximum requests per minute Enter the maximum number of MWI requests that can be made to the MWI MAS per minute. This field is available only if you have selected the Limit requests check box. The default is 60.

Tip: The first MAS in the list is the first MAS to which MWI requests are made. If required, you can use the Up

and Down

arrows to move MASs up or down the list.

Message Application Servers that support MWI This box displays a list of MASs in the voice mail domain that support MWI. If you are using per-port integration, (e.g. Inband, QSIG or set emulation), an MAS can support MWI only if it has an MWI port group defined.

To add an MAS to the list of MASs that support MWI, click the Add icon and type the name of the MAS.

To delete an MAS from the list, click the MAS that you want to delete and click the Delete icon . The system prompts you to confirm the deletion.
