Voice Messaging Systems 4
A voice messaging system (VMS) provides call-answering services and may
provide voice mail services. Table 4–13
describes the services available by
product (note that MERLIN LEGEND Mail services apply to MERLIN Mail). When
choosing or planning a VMS, keep the following considerations in mind:
■ Each of the VMS applications connects to a special tip/ring (T/R) jack,
called a
voice messaging interface
(VMI)
. If you plan to add voice
messaging to your system, ask your Lucent Technologies representative to
help you plan for VMI ports for your system. (You may already have
enough on existing modules.)
■ Voice messaging systems also require that you have a certain number of
touch-tone receivers to interpret the digits entered by callers using touch-
tone telephones. These are supplied on the control unit modules. The
number required depends upon the call volume you anticipate. Discuss this
with your Lucent Technologies representative.
■ Use password access to voice mailboxes to protect privacy.
* Not all Macintosh OS and UNIX system clients are supported. See the
