Abstract
The disclosed technology teaches testing voice connection routing over 911 circuits as if voice calls originated from an E911 device in coverage areas of cell tower locations, without requiring a physical presence of the E911 device in each coverage area. A remote test agent audio bridge and tester originates a first call to a test user with a first phone number, creates a media bridge, emulates an E911-compliant mobile device to originate a second call to a 911 operator, relays audio over the media bridge as a verbal exchange between the first and the second calls, and logs an evaluation of the verbal exchange. The emulation includes spoofing a call origination from an origination location being tested, the spoofed origination location being within coverage of an originating cell.
