Triggers for Turning MWIs On and Off
An MWI is a lamp, flashing LCD panel, or special dial tone on user phones that lets users know a voice message is waiting. The type of indicator depends on the phone system and the user phones. Phone systems that support message counts may also display the number of messages that the user has.
MWIs are not the same as message notification, which is the feature that notifies a user of new voice messages by calling a phone, pager, or other device, or by sending an email message.
The following events trigger Unity Connection to turn MWIs on and off:
When a message for a user arrives on the Unity Connection message store, Unity Connection notifies the phone system to turn on an MWI on the phone for that user.
Any message that arrives on the Unity Connection message store (for example, voice messages, emails, and faxes) trigger turning MWIs on and off.
When the user saves or deletes a read message, Unity Connection notifies the phone system to turn off the MWI on the phone.
When a user deletes a new message without listening to it, Unity Connection notifies the phone system to turn off the MWI on the phone.
When MWIs are synchronized, Unity Connection queries the message store to determine the status of MWIs on all phones, and resets the applicable MWIs.
However, an MWI remains on under the following conditions:
More messages are waiting to be heard. When all new messages are listened to, the MWI is turned off.
A new message arrives while the user is listening to the original message. When all new messages are listened to, the MWI is turned off.
The user listens on the phone to only part of the message, then either hangs up or skips to the next message before hearing the entire message.
The user listens the entire message. You can perform either of the following to turn off the MWI:
- Save or Delete the message after listening it.
- In Cisco Unity Connection Administration, Select Users. On the Search Users page, Select the alias of the user. On the Edit User Basics page of the user, navigate Edit > Playback Message Settings. On the Playback Message Settings page, Select Saved under When Disconnected or User Hangs Up During Message Playback field.
In an email application, in the Web Inbox, or Messaging Inbox , the user marks a listened-to message as unread.
Messages in an external message store do not trigger Unity Connection to turn MWIs on and off.
