VoIP Networks without PSTN — Example 2
Trunk Groups and Three Voice Daughtercards
This dialing scheme is used to set up additional sites on an existing VoIP network. Individual 
calls are routed to more than one possible destination, e.g., from Trunk G to Trunk E or 
Trunk F, depending on the number dialed. All telephone numbers in this example are unique 
across the VoIP network.
