Abstract:
A system for implementing a call processing application across a plurality of local area network (LAN) sites interconnected via a wide area network (WAN), with each LAN site comprising:(a) first high-speed network including one or more interconnected network elements for handling call processing traffic, each said network element of said first network having an associated internet protocol IP address; (b) second high-speed network including one or more interconnected network elements for handling call provisioning traffic, each said network element of said second network having an associated internet protocol IP address, said associated IP addresses of said first and second high-speed networks being logically segregated into one or more subnets for handling call traffic according to traffic latency requirements; and, (c) a router device configured to interface with each said first and second high-speed networks at a site via said one or more subnets and enable traversal of call processing and provisioning traffic over said WAN destined from one LAN site to another of said LAN sites, whereby network traffic latencies are minimized by routing different network traffic types via said one or more subnets.
