Design an advanced video/voice conferencing system by using API and TAPI telephony to transfer video/voice throw networks and voice throw analog telephone line.

Abstract

The Main idea of Voice over Internet Protocol (IP) is to transfer the sound to a group of Bits pool in the matrix of Byte Array and then to transport the encapsulation in Datagram packets or in Stream Data over the network in order to receive the audio by the other party through a collection of Packets again in the matrix of Byte Array. The reading process is done in accordance with the principle of FIFO (First in First out).
In this paper, a conference system has been designed to send and receive video and utilize the services API and TAPI telephony in order to transfer voice and video from one computer to another or to transfer voice from computer to landline Analog Phone and take advantage of TAPI telephony through the program contained in the operating system TAPI v3.0 in the operating system Windows XP. The proposed system has been designed by using Microsoft Visual Basic, Net programming. The designed system has been tested between two networks for sending and receiving video and sending voice between computer and phone. The results have displayed high quality of video using API and TAPI Technology.
