1. A method of 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 including:
triggering the bridging logic and causing the bridging logic to initiate a first call over the first cellular handset to a tester;
the bridging logic initiating a second call over the second cellular handset to a destination, wherein the second call is initiated over-the-air;
wherein 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; and
determining, by the tester, that the second call was established based on the relayed audio.
