MaxTalk (Voice and Video over IP)

Abstract

Til~.; lnkmd has matk our world a (jlubal Villag~.;; today we can gel into contact with our loved ones and f~i€mq~ overseas by various forms of lntemet Communication. Before the common use of lrite~et and e-mail, the only way one could communicate with people living far awaY.;wer.e the traditional PSTN ·and the surface mail network. But the cons were that long: distan'ce. and intemational calls ·were expensive and the transport delay associated with tlf~ post~J network was large. The revolutionary Simple Mail Transfer Protocol, one of the:: p~otocols in the TCP/IP protocol suite (developed by Advanced Research Project~ >~gency), made possible, sending of messages across the world in seconds. Then carr£e IRC (Intemet Relay Chat) and you could chat in real-time with your friends and family: Later: Voice · over IP (YoiP) applications like Net2Phone made it possible to make PC to PC and PC to Phone calls using the Intemet. This project is aimed at studying -'1nd using the ITU-T I-1 .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 Windows NetMeeting 3.0 SDK. MaxTalk also provides the facility of text chat and file transfer.
