Centralized Automated Attendant Programming 5

Programming for a centralized automated attendant is the same as for a local automated attendant with the following differences:

■If incoming calls at remote systems are to be answered by the centralized automated attendant, establish a VMI calling group at each remote system. The extension for the VMI calling group at the remote systems does not have to be the same at all systems. Assign the lines to the VMI calling group and assign the extension for the centralized VMS/AA as the single non-local member. In this case the special routing (absorbing and prepending digits) is not required and a pattern used for routing other voice calls can be assigned to the range. The number of digits to dial must be assigned to the range (new programming for Release 6.0 V11 and Release 6.1 and later systems).

!SECURITYlALERT:

Program the centralized VMS/AA to include all local and non-local covered extensions on any system. This is necessary for security purposes so that the automated attendant can be restricted to transfer only to subscribers.

See Appendix C for more information.

■All trunks within the private network should have unique trunk numbers. This allows the centralized automated attendant (such as Intuity) to deliver unique greetings based on the trunk on which the call was received.

Non-Local Dial Plan Numbering 5

As part of implementing a private network, the system manager at each private networked system specifies ranges of extensions for non-local systems connected directly or via another private network system to the local MERLIN LEGEND Communications System. The process does not affect programming on non-local systems but allows smooth communications among private networked systems.

This topic describes the following two management tasks:

■Specifying new extension number ranges

■Deleting extension number ranges

The extension ranges you enter using this procedure include the numbers that users on your system dial in order to make System Access (SA) calls to users on a non-local system. Users dial these calls in the same way that they dial inside calls on your local system. Numbering must be planned to avoid conflicts and provide unique and unambiguous extension numbers across private networks.
