Abstract:
The llllcmd has lltadc our world a ( Jlohal Vill;tgc; today we rail gd i111o ro111al'l with our loved ones and friends overseas by various forms or Internet Communication. Before the common usc or Internet and e-mail, the only way one could communicate with people liYing far away were the traditional PSTN and the surface mail network. But the cons ,,·ere that long distance and international calls were expensive and the transp011 delay associated with the postal network was large. The revolutionary Simple Mail Transfer Protocol, one of the protocols in the TCP/IP protocol suite (developed by Advanced Research Projects Agency), made possible, sending of messages across the world in seconds. Then came IRC (Internet Relay Chat) and you could chat in real-time with your friends and family. Later Voice over IP (VoiP) applications like Net2Phone made it possible to make PC to PC and PC to Phone calls using the fntemet. This project is aimed at studying and using the lTU-T H.323 Recommendation (a signaling protocol covering multimedia communications over LANs that do not provide a guaranteed Quality of Service). MaxTalk is a Win32 Desktop Application that uses ITUT H.323 Stack (by using services from Windows NetMeeting) for placing audio and video calls over a network (LAN or lntemet). MaxTalk has been developed in Visual C++ using Windo~vs· NdMeetii1g 3.0 SDK. MaxTalk also provides the facility of text chat and file transfer.
