Abstract:
A method of providing VoIP call routing in a virtual private network is disclosed. A first gatekeeper issues an information request to a gateway. The first gatekeeper receives from the gateway information organized in a string and based on the information in this string recommends to a second gatekeeper a transmission route through a virtual private network. The second gatekeeper then uses this recommendation to select the transmission route for a VoIP call through the virtual private network.
