ABSTRACT:
In one embodiment, a communication device204includes a voice communication module152to effect packet-switched voice communications over an untrusted network140; a secure communication module228to create a secured pathway258with a selected remote secure communication module124; and a VPN topology client232to contact a VPN topology server240to receive VPN topology information236that enables the secure communication module to create the secured pathway with the selected remote secure communication module. The VPN topology information includes IP addresses associated with remote secure communication modules, with each of the IP addresses having a corresponding range of node addresses serviced by the respective secure communication module.
