Abstract
A voice networking switching (VNS) appliance and methods for its use are disclosed. In a preferred embodiment, the VNS is an adjunct processor attached to a WAN node and software-configured to provide switching services for private network PBXs and PSTN central offices that have trunks ported to a WAN node. The switching services offered by the VNS allows PBXs to establish voice and data connections between each other, as well as with the PSTN, dynamically via Switched Virtual Circuits (SVCs) that are routed directly across a WAN. This arrangement eliminates the need for an extensive mesh of PVCs or leased “tie lines” carrying voice and data traffic between ported trunks across the WAN. Furthermore, private network end users can connect to the PSTN without their PBX having a direct connection to the PSTN. Likewise, a private network connection to a PSTN central office can be established in a location where no PBX is present.One desirable feature of the VNS as disclosed is breakout point selection. This feature allows a private network to have several, potentially geographically-dispersed connections to the PSTN. The VNS decides, for each private network-to-PSTN call, th…
