Introduction
Page 1-21Centralized Voice Messaging System
1
In the next chapter, we look at planning and setting up dial plans across a private
network, as well as the use of routing and other system management features.
Centralized Voice Messaging System 1
In Release 6.1 and later, MERLIN LEGEND Communications Systems connected
in a private network by tandem trunks may share a centralized voice and fax
messaging system and automated attendant (VMS/AA). The centralized VMS/AA
is connected to one of the MERLIN LEGEND systems which is then known as the
“VMS hub” system. “Remote” MERLIN LEGEND systems which are directly
connected to the “VMS hub” system by tandem trunks can then share the
Centralized VMS/AA.
Coverage and overflow calls using calling groups from the VMS hub and any of
the remote systems can be sent to the centralized VMS/AA. System users
retrieving voice mail can call the same number from any location and be directly
connected to the centralized VMS/AA. The centralized VMS/AA updates Message
Waiting lights across the private network for its subscribers on remote systems.
NOTE:
A private network can include more than one VMS hub with a centralized
VMS/AA system. Each system in the private network may also have local
VMS/AA systems.
However, a single extension can have only one
voice mailbox.
Configuration Requirements 1
A centralized VMS/AA is subject to the following configuration requirements and
constraints:
■ A DEFINITY ECS or DEFINITY Prologix
cannot
share a centralized
VMS/AA with a MERLIN LEGEND system.
■ The VMS hub system and all remote systems sharing a centralized
VMS/AA must be MERLIN LEGEND Release 6.1 or later systems.
■ Each MERLIN LEGEND system must be configured as Hybrid/PBX.
■ Networked MERLIN LEGEND systems that are not directly connected to
the “VMS hub” system (more than one span away) cannot share the
centralized VMS/AA.
■ More than one centralized VMS/AA can be configured in a single private
network. These centralized VMS/AA systems can share a VMS hub, or
have separate VMS hubs.
■ Any MERLIN LEGEND system in a private network may also have a local
VMS/AA system that is not shared.
■ Each extension in the system can have
only one
voice mailbox, no matter
how many VMS/AA systems are available.
