8.2.7.7 Message Waiting Indication
The device supports Message Waiting Indication (MWI) according to IETF Internet-Draft
draft-ietf-sipping-mwi-04, including SUBSCRIBE (to MWI server).
Note: For a detailed description on IP voice mail configuration, refer to the IP Voice
Mail CPE Configuration Guide.
The FXS device can accept an MWI NOTIFY message that indicates waiting messages or
that the MWI is cleared. Users are informed of these messages by a stutter dial tone. The
stutter and confirmation tones are defined in the CPT file (refer to the Product Reference
Manual). 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).
To configure MWI, use the following parameters:
