118 Chapter 6 Setting up VoIP trunks for outgoing calls
P0604630 03
Making calls through a private VoIP network gateway
From a telephone on Business Communications Manager Ottawa, a caller dialing to a telephone on
Business Communications Manager Santa Clara must dial the destination code, which includes the
destination digits for the Business Communications Manager Santa Clara remote gateway, and the
DN of the telephone. For example, dialing 3322 would connect as follows:
• 3 is the destination code. If a suitable level of QoS is available, the call is routed through the
VoIP trunks and through the remote gateway with a destination digit of 3. The call is sent
across the PDN using the IP address of the Santa Clara Business Communications Manager.
• 3322 is linked to the target line associated with DN 3322.
• The call arrives at the phone with the DN 3322.
If a user in Santa Clara wanted to make a local call in Ottawa, they would dial 29, followed by the
local Ottawa number. The digit 2 accesses the remote gateway for the VoIP line. The digit 9
accesses an Ottawa outside line.
