Abstract
A method for communicating packet multimedia data between a source endpoint and a destination endpoint is disclosed, wherein at least the source endpoint is within a virtual private network, and comprises the steps of receiving, at a signaling controller, a first signaling packet from the source endpoint, wherein the source endpoint is within a virtual private network; determining whether the source endpoint and destination endpoint may communicate directly over the same virtual private network; when the source endpoint and destination endpoint cannot communicate directly over the same virtual private network, associating a unique identifier of the source endpoint with a virtual private network identification marker; when the source endpoint and destination endpoint can communicate directly over the same virtual private network, instructing the source endpoint and destination endpoint to communicate media packets directly.
