MWI, Message Waiting Indicator, is a commonly supported phone feature indicating that new voicemail messages have been received.
MWI typically involves a flashing light and optional audio alert with a dedicated button to quickly dial into your voicemail box.
To use the MWI feature your phone must be configured with your sipgate Voicemail box number.
MWI is offered in addition to free email notifications and optional SMS voicemail alerts.
sipgate has tested and verified the operation of MWI with the following VoIP phones:
