Abstract
A method and system for providing reliable path for Direct Inward Dial (DID) calls on networks, e.g., Time Division Multiplexed (TDM) networks, the packet networks Voice over Internet Protocol (VoIP) and Service over Internet Protocol (SoIP) networks are disclosed. In one embodiment, the present method enables the customers to request for a reliable path for Direct Inward Dial (DID) calls. For example, the present method enables a service provider to connect a customer's switch, e.g., a PBX, to two or more switches (or softswitches) via two separate DID trunk groups. The method also enables the service provider to create a DID trunk group between the two or more switches (or softswitches) connected to the customer's switch. With this architecture, the service provider is able to continue to forward DID calls towards the customer's switch even if one of the two separate DID trunk groups has failed.
