Abstract: The technology includes a method, computer medium, and system for testing transport audio quality irrespective of tester location. The technology involves a virtual test agent (VTA) selecting a Mobility Management Engine (MME) for routing a second call through a Serving Gateway (SGW) assigned by the MME for audio communication with a tester terminus over a transport segment under test, so a tester can evaluate audio quality over the transport segment under test. The VTA makes a first call to a tester appliance, and makes a second call, over the transport segment under test, to the tester terminus by signaling the MME. The VTA bridges the first and second calls by relaying audio during a test of subjective audio quality, whereby the bridging assures that the relayed audio in the second call continues to be relayed over the transport segment under test and not re-routed by core network components.

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.
