Siemens 1190 用户手册

A Voice Mail Server outsourced to a local carrier works 

for specified extensions grouped as a "External MWI 

Group" during the configuration of the system. When 

there is a message in the mailbox, the extensions that 

belong to this group receive a MWI (Message Waiting 

Indicator) from the external Voice Mail Server.

The Message Waiting Indicator (MWI) is used in the Hi-

Path 1100 to help manage voice mail. With this feature 

when a mailbox (internal or external) receives a new 

message, a signal or tone indicates that there is a mes-

sage waiting.

This indication is provided in the following manner:

• By means of a key programmed as a MWI, in the 

case of System Telephones.

• By means of an icon shown on the display, in the 

case of  System Telephones or standard telephones 

with Caller ID (CLIP-FSK);

The signal indication is activated when the first mes-

sage is received in the mailbox. The indication is deacti-

vated automatically by the Voice Mail Server.

When there is a message in the user’s mailbox, the key 

configured will blink as an indication.

A programmable telephone key is assigned as an indi-

cator for a new message in the mailbox by using an in-

ternal Voice Mail Server.

Press this key.

[1] When using an internal Voice Mail Server, extensions must be pro-

grammed in the Subscriber Group to which Voice Mail was as-
signed (see Programming an Extension - UCD Subscriber Group in 
the Programming Manual). 

 

When using an external Voice Mail Server (contracted with a local 
carrier), the extensions assigned to voice mail must be pro-
grammed and the service must be enabled in the external MWI 
Group (see Programming an Extension - External MWI Group in the 
Programming Manual).

[2] For System Telephones without a display the signaling must be 

programmed using the HiPath 1100 Manager application.
