Voice Mail

messages.

MWI for Voice Mail Configuration
Yealink phones support both solicited and unsolicited MWI.
Unsolicited MWI:
The IP phone sends a SUBSCRIBE message to the server for message-summary updates. The
server sends a message-summary NOTIFY within the subscription dialog each time the MWI status changes. Unso-
licited MWI is a server related feature.
Solicited MWI:
The IP phone can subscribe to the MWI messages to the account or the voice mail number. For soli-
cited MWI, you must enable MWI subscription feature on the phones.
The following table lists the parameters you can use to configure MWI for voice mail.
