A mobile handset call testing system and method. Mobile wireless handsets are tested under the control of a controller. The controller causes an autodialler to dial a call request on a transmitting handset. The call request is received by a wireless network and communicated to a receiving handset. RF sensors at the transmitting and receiving handsets provide the controller with signals indicative of the RF transmissions emanating from the handsets. The controller determines whether the outgoing call request and/or the incoming call request are successful based upon the detected RF transmissions.
