P0911590 Issue 02 Enterprise Edge 2.0 IP Telephony Configuration Guide
The impact 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 codes that match the Private Network Access
Code plus digits matching to calls terminating in the local PSTN. For example,
if the Private Network Access Code is ‘9’, the node in Ottawa can require a
destination code of ‘91613’. In the same way, Toronto can require the following
destination code: 91416.
Note: For IP trunks, ensure the programming selection is Line Pool A.
To allow for fallback to PRI trunks when the IP trunks are overflowed, you must
program the following Routing service settings:
• Set the start and end times for Sched 4 to 1:00 to allow IP calls can 24 hours a
day.
• Program the Sched 4 Service setting to Auto and enable overflow routing by
changing the Overflow setting to Y (Yes).
• Define a control set for all sets on the system that make calls over IP trunks. See
the Enterprise Edge Programming Operations Guide for more information.
