Abstract

The objective of this project is to develop a call logging system that can track the dialed number, duration, date and call cost. The Dual Tone Multi-frequency (DTMF) Detector was developed to detect the frequencies of the telephone keypad and send the data through the computer. The concept of this system is when the dialer pressed the keypad at the telephone, the DTMF detector detect the frequencies and then sends the bit through the computer to recognized and record the number on the Graphical User Interface (GUI). This system uses the Microsoft Visual Basic 6.0 as a Graphical User Interface (GUI) to record the information. The final output of this project is a complete telephone call logging system that operates together with Personal Computer (PC). The advantage of using this system is it can reduce the call cost and less time to check the dialed number.
