Abstract
A telecommunications platform that provides redundant interfaces to a telecommunications system for multiple IP based telecommunication devices. The telecommunications platform includes a gateway cluster with two or more signaling gateways. Each signaling gateway is assigned a point code for being accessed by devices in the telecommunications system. The gateway cluster is assigned a virtual point code. Any of the IP based telecommunications devices can be accessed by the telecommunications system by routing to the virtual point code through one of the signaling gateways in the gateway cluster. Thus, if one of the signaling gateways is not available, the IP based telecommunications devices can still be accessed through one of the other signaling gateways in the gateway cluster.
