Figure 113 Calling into a remote node from a public location

Call process

Based on Figure 113, this is how the call would progress:

1 A home-based employee in Santa Clara wants to call someone in Ottawa, so they dial into the

local BCM network using the access code for an unsupervised trunk (not VoIP trunks) and the

destination code and DN for the person they want to reach on System B.

2 When the call is received from the public network at System A (Santa Clara), the system

recognizes that the received number is not a local system number. The call is received as a

public call.

3 System A has a route and destination code that recognizes the received number and destination

code as belonging to the route that goes to System B (Ottawa). System A passes the call to

System B over a dedicated trunk, in this case, a VoIP trunk. This call is now designated as a

private call type.
