The implications on the configuration on each node are:
• each node must have the Private Network Access Code set to the value 9.
• each node must have destination code(s)that match the Private Network Access
Code plus digits corresponding to calls terminating in the local PSTN. For
example, if the Private Network Access Code is ‘9’, the node in Ottawa would
require a destination code of ‘91613’. Similarly, Toronto would require the
following destination code: 91416.
Note: Ensure that Line Pool A is used for IP trunks.
To allow for fallback to PRI trunks when the IP trunks are congested, you must also
program the following Routing service settings:
• Set the start and end times for Sched 4 to 1:00 so that IP calls can be made 24
hours a day.
