Dialing plan using public lines
Installer password required
For example, imagine that you have a system in a network of
three offices such as New York, Toronto, and Santa Clara.
If there is no routing, callers would have to dial this way:
• A Norstar user in New York would have to select a line
pool and dial a number such as 1-416-555-3227 to reach
telephone 3227 in Toronto (416).
If there is routing:
• you could create a destination code of 3, and create a route
that uses the proper line pool and DialOut. In this case, the
user simply dials 3227, the receiving telephone DN being
227.
In the DialOut, P stands for pause, a host system signaling
option. Press
≤‡°
to insert a 1.5-second pause in the
dialing string. See the Modular ICS 7.1 System Coordinator
Guide for information about other signals.
Destination code numbering in a network
Because the system checks the initial digits of a call against the
routing tables, each type of internal or external call must begin
with a unique pattern of digits. The following table gives a
sample plan for how initial digits are assigned in a network of
systems with three-digit DNs.
