Message Waiting Indication (MWI)
Message Waiting Indication (MWI) is the same as Calling Line Indication (CLI) message wait
service. On a normal ISDN call, a Station can leave a Message Wait for an unavailable station
on another node (CLI message wait must be enabled). MWI is indicated by the CLI message
on the Station LCD panel. Additionally, it can be supported by supplementary service (without
CLI) by pressing the {MSG WAIT} button when the Net Call Ring-Back tone is received.
CONDITIONS
- MWI only can be registered at the Station hearing a ring back tone.
- MWI notification is displayed at the Called Station LCD.
- When the System presents the Call-Back according to MWI data, the CO Line is
selected within the Network CO group.
OPERATION
To register and retrieve MWI:
1. Initiate a Net Call to another station on another node; the caller will hear a Ring-Back
tone.
2. While hearing the Ring-Back tone, the caller can either,
a.) Press the [MSG/Callbk] button.
OR
b.) Press the [TRANS] button and dial the {Message Wait Register Feature Code}.
3. MWI is left to the called station, and a flashing [MSG/Callbk] button indicates the
message waiting.
4. At the called Station, press the flashing [MSG/Callbk] button; the Calling Station
number is displayed.
