ABSTRACT:
A method and apparatus for enabling calls destined for a terminating point on a packet network, e.g., a VoIP network, that is experiencing a service disruption to be forwarded by the network to another endpoint is disclosed. The method enables subscribers to register an alternative number, such as a cell phone number, a relative's phone number, or a work number, that the network can use to forward calls in the event of a service disruption. In one embodiment, the provider can even use an alternative transport network, such as the PSTN, to forward these calls until the VoIP network service is restored.
