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’’.
