The technology includes a method, computer medium, and system for remote testing over-the-air (OTA) audio quality using a test platform positioned at core network, the test platform comprising first and second cellular handsets and bridging logic that interconnects, controls, and bridges the first and second cellular handsets. The method includes triggering the bridging logic. The bridging logic initiates a first call over the first cellular handset to a tester, and initiates a second call over the second cellular handset to a destination, wherein the second call is initiated over-the-air. The bridging logic and the first and second cellular handsets are positioned in a location that causes routing by a cellular network of the first call over a segment under test. The bridging logic bridging audio between the first and the second calls, including relaying audio. The tester determines that the second call was established based on the relayed audio.

Over-the-air audio quality testing remote from testing site

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.
