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.

(2) looking up said assigned telephone number in a provider telephone number data base to ascertain at least one second predetermined data element associated with said registered geographic locus;

(c) during said pre-call routing process, comparing said at least one first predetermined data element with said at least one second predetermined data element; and

(d) if said at least one first predetermined data element does not substantially match said at least one second predetermined data element, setting a discrepancy flag among said other data to effect said alerting and effecting routing of said emergency call.

10.
