3.5.5 Message Waiting Address
The MWI (Message Waiting Indicator) is an optical signal which indicates that voicemail mes-
sages are on the server. Depending on the SIP server / gateway in use, the Message waiting
server address, that is the address or host name of the server that sends message waiting
notifications to the phone, must be configured.
With Asterisk, this setting is not typically necessary for enabling MWI functionality.
