1. A method of blocking a source device of a probable nonlegitimate emergency call, comprising:

  • receiving an incoming emergency call from a physical wireless device associated with a given location;

    initiating a request to a caller data server in communication with a blacklisted caller database to perform a lookup of other emergency call records recently made from a same general location as said given location, and all routed to a same public safety answering point (PSAP);

    comparing said incoming emergency call to said emergency call records to determine if multiple emergency calls have been made recently from said physical wireless device;

    receiving a feedback message regarding a probability of said received emergency call being a non-legitimate emergency call; and

    adding, to said blacklisted caller database, an identifying telephone number or mobile identification number (MIN) of said physical wireless device when said probability is beyond an acceptable threshold amount.
