Abstract

See full text

A method and system allow a subscriber to test emergency 911 telephone services routed from the subscriber's location over a network to a response center. An alternative dialing code (*911) is provided for testing, and when a call placed by a subscriber to the alternative dialing code is received in the network, the network identifies the response center to which a 911 call placed from the subscriber's location is routed. An answering device is provided with status information with respect to the identified response center, and calls placed by the subscriber to the alternative dialing code are routed to the answering device, whereby when a subscriber places a call to the alternative dialing code, the answering device will supply the subscriber with status information with respect to the identified response center that receives a 911 call from the subscriber's location.
