ABSTRACT:
A method and apparatus for an authorized user of a cellular mobile radiotelephone to easily obtain data and performance evaluation of the telephone, such as the electronic serial number (ESN), the mobile telephone number (MID), and transmitted audio information that permits evaluation of the voice modulation performance of the telephone. By calling a dedicated telephone number, an authorized operator, such as a cellular agent, can contact a computer with voice response capability, which is associated with the electronic mobile exchange (cellular switch). The computer then transmits to the agent a voice prompt requesting a password. Upon correct entry of the password, the computer initiates a trunk trace of the incoming call. The trunk trace identifies the ESN and MID for the telephone used to make the call. The computer reports that data to the calling party, via the cellular network. Having supplied the telephone user or agent with the data, the computer then prompts the agent to record a voice sample on the system for subsequent re-transmittal to the telephne. By evaluating the re-transmitted voice sample, the agent can evaluate the voice modulation capability of the telephone.
