Abstract: A method for indicating certainty of origin of an IP emergency call includes: (a) entering a registered address related with an assigned telephone number for a VoIP calling instrument in a provisioning system database; (b) when the call is initiated with a VoIP Service Provider (VSP) unit having an assigned internet address; in no particular order: (1) looking up the assigned internet address in a first database to ascertain a first data element relating to a VSP unit geographic region; and (2) looking up the assigned telephone number in a second database to ascertain a second data element relating to a registration geographic region containing the registered address; (c) comparing the first and second data elements; (d) if the data elements match, delivering the call; and (e) if the data elements do not match: (1) setting a flag presenting an alert to the call taker; and (2) delivering the call.

Abstract: A method for providing an indication of certainty of location of origin of an internet protocol emergency call including: (a) routing the emergency call from an originating internet protocol calling instrument via an internet protocol telephone service provider unit to a call taker; the provider unit having a provider telephone number; the emergency call being accompanied by an internet address for the originating calling instrument; (b) in no particular order: (1) looking up the internet address in a data base to ascertain a first data element; and (2) looking up the provider telephone number in a data base to ascertain a second data element; (c) comparing the first and second data elements; (d) if the first and second data elements match, continuing handling the emergency call; and (e) if the first and second data elements do not match, presenting an alert to the call taker.

Abstract: The invention comprises a communication network that includes a plurality of conforming emergency systems, a packet network, and an emergency services network. The emergency services network includes a plurality of response gateways and a plurality of emergency services. Each of the conforming emergency systems facilitates the establishment of a media channel with one of the response gateways. In any one of the conforming emergency systems, responsive to establishing a media channel over the packet network with a response gateway and responsive to an emergency event (e.g., a 9-1-1 call, a 1-1-2 call, etc), the conforming emergency system transmits a retrieval key for the emergency event over the established media channel to the response gateway. The response gateway transmits a query for information corresponding with the retrieval key.
