Configuring AMWI and VMWI

First Published: November 19, 2010

 

This module describes the configurable audible message waiting indication/visible message waiting indication (AMWI/VMWI) feature for Skinny Client Control Protocol (SCCP)-controlled Analog Ports. This feature provides users with the option to enable one message waiting indication (MWI): audible, visible, or both.

This feature is supported for analog endpoints that are connected to Foreign Exchange Station (FXS) ports or a Cisco VG224 Analog Phone Gateway and controlled by a Cisco call-control system, such as a Cisco Unified Communications Manager (Cisco Unified CM) or a Cisco Unified Communications Manager Express (Cisco Unified CME).

Finding Feature Information in This Module

Your Cisco IOS software release may not support all of the features documented in this module. To reach links to specific feature documentation in this module and to see a list of the releases in which each feature is supported, use the “Feature Information for Configurable AMWI and VMWI” section.

Information About Configurable AMWI and VMWI

To enable SCCP supplementary features on analog phones connected to FXS ports on a Cisco voice gateway, you should understand the following concepts:

Feature Summary

Table 1 contains information about SCCP-based Configurable AMWI and VMWI on Cisco Voice Gateways.

Table 1 Configurable AMWI and VMWI

Feature
How Phone User Accesses Feature
Configuration on Call-Control System
Configurable AMWI and VMWI

Allows users to configure AMWI only, VMWI only, or both.

When a voicemail is available, the user goes offhook to hear a special AMWI tone or goes onhook to see an MWI light (when the phone is equipped with one).

No configuration tasks required on your Cisco call-control system.

Configurable AMWI and VMWI

MWI is used to remind you that there is a voicemail message waiting. When a voicemail is available, the phone receives AMWI, which plays a special AMWI tone when you go offhook. A VMWI, which turns on an MWI light, is also activated whenthe phone is equipped with one. No configuration tasks are required to enable MWI feature for analog phones because it plays both AMWI and VMWI by default. However, you can configure your phone to have VMWI or AMWI only.

When configuring MWI, you need to make sure that there are no existing voicemail messages. Configuring MWI while the phone still has voicemail messages is not supported by this feature. You need to clear all voicemail messages and make sure VMWI/AMWI is not active before configuring the MWI setting.

The two types of VMWI, the frequency-shift keying message and DC voltage, are both supported by this feature.

How to Configure AMWI and VMWI

DETAILED STEPS

Command or Action
Purpose

Step 1

enable

 

Router> enable

Enables privileged EXEC mode.

  • Enter your password if prompted.

Step 2

configure terminal

 

Router# configure terminal

Enters global configuration mode.

Step 3

stcapp supplementary-services

 
Router(config)# stcapp supplementary-services

Enters supplementary-service configuration mode.

Step 4

port port-number

 
Router(config-stcapp-suppl-serv)#port 2/2

Specifies analog FXS voice port on which STCAPP supplementary-service features are to be supported.

• port-number —Voice port number. Range is 2/0 to 2/23.

Step 5

mwi { audible | visible | both }

 

Router(config-stcapp-suppl-serv-port)#mwi audible

 

Enables mwi as audible only (AMWI), visible only (VMWI), or both (default configuration).

  • audible —AMWI is enabled.
  • visible —VMWI is enabled.
  • both —Default configuration. Both AMWI and VMWI are enabled.

Note The current configuration is that MWI (AMWI/VMWI) is automatically turned on when the port is configured in SCCP, MWI cannot be turned off in SCCP.

Step 6

end

 
Router(config-stcapp-suppl-serv-port)#end

Exits configuration mode and returns to privileged EXEC mode.
