Non-Local Dial Plan Extension Ranges 3
In Release 6.0 and later systems (Hybrid/PBX mode only), the system manager
can enter ranges of extensions for non-local systems networked to the local
MERLIN LEGEND Communications System. The process does not affect
programming on non-local systems but allows smooth communications among
networked systems.
This topic describes the following two procedures:
■Specifying new extension number ranges
■Deleting extension number ranges
The extension ranges you enter using this procedure are the numbers that users
on your system dial in order to make System Access (SA) calls to users on the
remote system. Users dial these calls in the same way that they dial inside calls
on your local system. In most cases they should be the same numbers that us ers
in the remote networked system dial to reach one another. Numbering must be
planned to avoid conflicts and provide unambiguous extension num bers across
private networks.
Non-local dial plan calls are routed over pools of private trunks using UDP routing.
Maintaining existing dial plans when systems are networked may not be possible
due to ambiguity or when one system’s dial plan changes. UDP routing using digit
absorption and digit prepending, which allow dialed numbers to be modified
before they are actually sent to the remote system, may help to minimize
changes. However, this will quickly increase dial plan complexity for private
