Centralized Voice Messaging in a Private Network
The MERLIN Messaging System can also be used in a Centralized Voice Messaging
configuration in a private network. MERLIN LEGEND Communications Systems (Release
7.0 and later) and/or MERLIN MAGIX Integrated Systems connected in a private
network by tandem trunks may share a centralized MERLIN Messaging System connected
to one of the MERLIN communications systems, which is then known as the "VMS
hub" system. "Remote" MERLIN communications systems which are directly connected
to the "VMS hub" system by tandem trunks can then share the centralized MERLIN
Messaging System.
Coverage and overflow calls using Calling Groups from the VMS hub and any of
the remote systems can be sent to the centralized MERLIN Messaging System. System
users retrieving voice mail can call the same number from any location and be
directly connected to the centralized MERLIN Messaging System. The centralized
MERLIN Messaging System updates MessageWaiting lights across the private
network for its subscribers on remote systems.
The following are general guidelines for configuring a centralized MERLIN Messaging System. For complete details and programming instructions for networked systems, refer to the Network Reference for the communications system.
- On the communications systems in the private network, configure the following:
- The extensions and lines on all networked communications systems should
be numbered unambiguously. For example, on communications system 1, extensions
could be numbered between 10001999, on communications system 2, between
20002999 and on communications system 3 between 30003999, etc.
The lines on communications system 1 could be 18011880, on communications
system 2 28012880; and on communications system 3, 38013880.
- On the VMS Hub system (where the MERLIN Messaging System module is physically
located), program the communications system for the MERLIN Messaging System
as if it were a stand-alone communications system.
- On each remote communications system that will share the MERLIN Messaging
System, program the communications system for the MERLIN Messaging System
as if it were a stand-alone communications system with the following exception:
- For the MERLIN Messaging System Calling Group, program only one member
a nonlocal Uniform Dial Plan (UDP) number that directs
calls to the MERLIN Messaging System Calling Group on the VMS Hub system.
- For MessageWaiting Lights to work across private networks, the communications
systems must be connected via point-to-point T1 programmed as PRI, T1TIE,
or E&M TIE lines. Also, the Switch Number must be programmed (refer to the
Network Reference for complete details).
- On the MERLIN Messaging System, configure the following:
- Create a mailbox for each local and nonlocal extension that is to receive
Voice Mail coverage.
- Create a transferonly mailbox for each local and nonlocal extension
as required.
- Miscellaneous configuration information:
- Only the VMS Hub system can put the MERLIN Messaging into open and closed
schedules.
- To use Night Only Call Handling, Delayed Call Handling or Immediate Call
Handling, use the configuration and programming instructions for each type;
for the communications system actions, program each of the communications
system in the private network that will share the MERLIN Messaging System
using instructions in the Network Reference.
