Based on the VoIP Example 1 ( Basic Configuration and Registration ), we will
introduce how to dial the VoIP call through an encrypted VPN tunnel.
In this example Vigor 3300V acts as a bridge accepting incoming VPN connections from
the other two routers ( Vigor 2900V and Vigor 2200V). The VPN traffic between Vigor
2900V and Vigor 2200V are all passed through Vigor 3300V. These three sites internal
networks must be within the same subnet ( 192.168.X.X ). Either site can ping the other
two routers. Then you can make a VoIP call through the encrypted VPN tunnel by
directly dialing remote router's LAN IP.
