Note: When a call gets rerouted over the PSTN due to congestion, the user may see

a prompt “Expensive route.” The warning indicates that toll charges may be applied

to this call.

Users at both locations access the public network by dialing “9”, followed by the

public number. For example, a user in Toronto might dial 9-555-1212 (for a local

call), or 9-1-613-555-1212 (for a long distance call to Ottawa). Local calls would

be sent directly to theCentral Office over PRI trunks. Longdistance calls to Ottawa

would be sent over IP trunks; the Ottawa system would tandem these calls to the

local Central Office over PRI trunks.

Private network calls are made by dialing a 4-digit private network DN. For

example, if a user in Toronto wants to call a user in Ottawa within the private

network, they dial 6221.

Note: Enterprise Edge VoIP Gateway requires a software keycode.

The Call Manager at the Toronto office examines the Called Party Number digits

and determines that it should be routed to the IP address corresponding to the

Ottawa office. The Ottawa office receives the call, sees that the leading digit(s)

matchitsPrivateNetwork Access Code, and usesadestination codetoroute the call

over its public trunks to the PSTN.

This is a simplified example where only calls to the 613 Area Code are routed by

the Ottawa node. In a real world configuration, it would also be desirable to handle

Area Codes that are ‘close’, for example Montreal: 514.
