Avaya IP Office

The Avaya IP Office platform is the ultimate in converged voice and data technology. IP Office brings a combination of voice and data applications formerly reserved for only the largest corporations. Cutting edge customer service with easy to use tools is now available to the smallest of businesses.





Message Waiting Indication

Message waiting indication (MWI) or a message lamp is supported for a wide variety of phones. It is used to provide the user with indication of when their voicemail mailbox contains new messages. It can also be configured to provide them with indication when selected hunt group mailboxes contain new messages.

Avaya digital and IP phones all have in-built message waiting lamps. Also for all phone users, the IP Office Phone Manager application provides message waiting indication.  


Analog Phone Message Waiting Indication
For analog phones, IP Office 3.1 provides support for a variety of analog message waiting indication (MWI) methods. Those methods are 51V Stepped, 81V, 101V and Line Reversal. The 101V method is only supported when using a Phone V2 expansion module.

81V is typically used in European countries. 51V Stepped is used in most other countries. However the actual method used for a particular model of analog phone should be confirmed with the phone manufacturer's documentation.

The method used for an individual analog extension is set for the Extn | Extn | Message Waiting Lamp Indication Type field. This field also provides options for None (no MWI operation) and On. On selects a  default message waiting indication method based on the system locale.

'On' Method



Belgium, Denmark, Finland, France, Germany, Greece, Hungary, Iceland, Italy, Netherlands, Norway, Poland, Portugal, Russia, Saudi Arabia, Sweden, Switzerland, United Kingdom.

51V Stepped

Argentina, Australia, Brazil, Canada, Chile, China, Columbia, Japan, Korea, Mexico, New Zealand, Peru, South Africa, Spain, United States.

  • For the United Kingdom system locale (eng), the default Caller Display Type (UK) allows updates of an analog phone's ICLID display whilst the phone is idle. The IP Office uses this facilities to display the number of new messages and total number of messages in the users own mailbox. This feature is not supported with other Caller Display Types.  


Hunt Group Message Waiting Indication
By default no message waiting indication is provided for hunt group voicemail mailboxes. Message waiting indication can be configured by adding an H entry followed by the hunt groups name to the Source Numbers tab of the user requiring message waiting indication for that hunt group. For example, for the hunt group Sales, add HSales. Hunt group message waiting indication does not require the user to be a member of the hunt group
