27.8 Message Waiting Indication
The device supports Message Waiting Indication (MWI) according to IETF RFC 3842. The
device also supports subscribing to an MWI server (using SIP SUBSCRIBE messages).
For FXS interfaces, the device can accept a SIP MWI NOTIFY message that indicates
waiting messages or cleared messages. Users are informed of these messages by a
stutter dial tone. You can define the stutter and confirmation tones in the CPT file. If the
MWI display is configured, the number of waiting messages is also displayed. If the MWI
lamp is configured, the phone’s lamp (on a phone that is equipped with an MWI lamp) is lit.
The device can subscribe to the MWI server per port (usually used on FXS) or per device
(used on FXO).
For more information on configuring IP-based voice mail, refer to the IP Voice Mail
CPE Configuration Guide.
To configure MWI, use the following parameters:
