Voice Messaging Systems 4
A voice messaging system (VMS) provides call-answering services and may
provide voice mail services. When choosing or planning a VMS, keep the
following considerations in mind:
■ Each of the following 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.
■ You may want to use password access to voice mailboxes, to protect
business and personal privacy.
■ If you plan to use an outcalling feature (see Table 4–13 for an explanation),
you should consider using calling restrictions to prevent this feature from
being abused by people who may use it to make fraudulent toll calls.
NOTE:
In Release 3.1 and later systems, all VMI ports are by default
restricted from outcalling in Hybrid/PBX systems, using an extension
FRL of 0. VMI ports are automatically assigned a special Disallowed
List that restricts many types of calls made by fraudulent callers. In
addition, these ports are outward-restricted. For more information,
see ‘‘
Calling Restrictions’’ on page 4-40.
■ The system provides two specific features that work with voice mail
systems: Direct Voice Mail and Coverage VMS Off. Direct Voice Mail
allows transfer of a caller to a voice mail box, without ringing the mailbox
owner at his or her extension. Voice mail can be designated to cover calls
in the same fashion that a calling group can; Coverage VMS allows a user
to turn this feature on or off and requires a programmed button. Consider
how you might take advantage of these features in your company.
NOTE:
Before planning your voice messaging system, see the Security Alert
on page 4-62
. Also consult ‘‘Security of Your System:
Preventing Toll Fraud’’ in Appendix A, ‘‘Customer Support
Information’’.
