External Server
A voice mail server outsourced to a local carrier works
for specified extensions grouped as a "External MWI
group" during configuration of the system. When there
is a message in the mailbox, the extensions that belong
to this group receive a MWI (Message Waiting Indica-
tor) from the external voice mail server.

Message Waiting Indicator (MWI)

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.
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.

MWI for Analog Telephones

A message in the user's mailbox may be indicated as
follows:
• By means of an icon shown on the display, in the
case of standard telephones with Caller ID (CLIP-
FSK)
• By means of a distinctive audible tone, in the case
of analog telephones without Caller ID (CLIP);
[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 activated in the external MWI
group (see Programming an extension - External MWI group in the
programming manual).
[2] Analog Telephones that have the CLIP FSK feature available indi-
cate the presence of MWI service by an icon on the display or
some other type of indication.
