User Guide for the SIP-T29G IP Phone
176
The SIP-T29G IP phone supports MWI when receiving a new voice message. If someone
leaves you a voice mail, you will receive a message waiting indicator. MWI will be
indicated in three ways: a warning tone, an indicator message (including a voice mail
icon) on the LCD screen, and the power indicator LED slow flashes red. This will be
cleared when you retrieve all voice mails or delete them.
The MWI service is unsolicited for some servers, so the SIP-T29G IP phone only handles
the MWI messages sent from the server. But for other servers, the MWI service is
solicited, so the SIP-T29G IP phone must enable subscription for MWI.
