NOTE:

It is recommended that PRI lines, rather than tie lines, be used between MERLIN LEGEND Communications systems in a private network that utilizes the Centralized Voice Mail feature. Refer to Table 1–1, page 1-11 for advantages of PRI lines.

Because tandem switching allows intersystem coverage of calls to other systems on the private network, it is important to note that coverage to the centralized VMS/AA from remote private network systems must be limited to only one span. This means that a call may only pass through one tandem trunk to the centralized VMS/AA on the hub system.

It is also important to note that if a DEFINITY ECS or DEFINITY Prologix Solutions system is a networked system, it can not receive coverage to the centralized VMS/AA. Also, if the DEFINITY ECS or DEFINITY Prologix Solutions is the hub system in the star configuration, a centralized VMS/AA servicing connected MERLIN LEGEND Communications systems is not possible.

It is also possible to have more than one centralized VMS/AA on different hubs, and also have local VMS/AA systems attached to individual MERLIN LEGEND systems. However, each extension in the private network can have only one voice mailbox.

For Release 6.0 networks, Centralized Voice Mail is not available. Each system must have its own voice mail application for voice mail coverage. However, with Release 6.0, Version 11, calls can be routed over the private network from a centralized automated attendant.
