Audible Message Waiting Indicator

Audible Message Waiting Indicator Overview

You can configure Audible Message Waiting Indicator (AMWI) to play a stutter dial tone on the Cisco Unified IP Phone to notify users of new voice messages. Users hear a stutter dial tone whenever the phone goes off hook on a line on which a voice message was left.

You can configure AMWI for all the phones in a cluster or for only certain directory numbers. The directory-number-level configuration takes precedence over the cluster-wide configuration.

Audible Message Waiting Indicator Prerequisites

You can configure AMWI only on Cisco Unified IP Phone that are running phone firmware Release 8.3(1) or later.

Audible Message Waiting Indicator Troubleshooting

Audible Message Waiting Indicator Is Not Heard on the Phone

Problem Phone does not play stutter dial tone to notify the user of new voice messages.

If the user uses an SCCP phone, check the following:

  • Ensure that the phone firmware release is 8.3(1) or later.

  • Check the AMWI setting for the phone and the line on which the user went off hook.

  • Verify that the Cisco CallManager service is running on the server.

  • Check the sniffer trace between the phone and Unified Communications Manager. Make sure that the phone receives the StartTone message with tone type equal to 42.

If the user uses a SIP phone, check the following:

  • Ensure that the phone firmware release is 8.3(1) or later.

  • Check the line (directory number) configuration. The phone must display the settings such as line1_msgWaitingAMWI : 1, line2_msgWaitingAMWI : 0.

  • Ensure that the Stutter Message Waiting check box is checked in the SIP Profile Configuration window in Cisco Unified CM Administration.

Localized AMWI Tone Is Not Played in a Specific Locale

Problem  The phone that is configured in a non-English locale does not play the localized tone.

Solution Check the following:

  • From Cisco Unified CM Administration, verify the User Locale in the Device Profile Configuration window (Device > Device Settings > Device Profile).

  • Make sure that the user resets the phone after changing the locale.

  • Check user/local/cm/tftp /<locale name> directory and verify that the AMWI tone is defined in the localized g3-tones.xml file.
