Abstract
A method and apparatus for simulating telephony services and providing information about telephony services and products without the use of a public carrier telephone system. The system includes at least one Telephone Interface (TI), connected between a telephone and the simulation system. The emulator receives, decodes and validates a user initiated command signal, converts it into a control signal and activates a playback sequence which emulates telephone services. A plurality of different telephone functions and services can be simulated without connection to external telephone lines or wireless service.
