A system and method for receiving data and commands from a telephone are described. The system receives a signal (such as a DTMF signal) from a telephone. The system identifies a symbol (i.e., a key) associated with the signal, and determines a duration of the signal. Then, the system stores the symbol and duration in a queue. The received signals are preferably processed by service processors. The service processors translate the received signals according to their respective symbols and durations with reference to a translation table. These service processors provide interactive telecommunication services to telephone users. Also described is a calculator service processor that provides a calculator service to telephone users. The calculator service processor translates some of the signals as operands, and others of the signals as operators. The calculator service processor preferably translates these received signals according to their respective symbols and durations. The calculator service processor applies the operands to the operators to thereby perform mathematical operations.
