I'm Madhu Yarlagadda, Director, Real Time Communications atYahoo! In my last Whiteboard I talked about voice over IP being ready forprimetime. In this session, I'm going to talk about the future of voice overIP, what I call it CoIP. CoIP stands for communications over IP. In the world ofcommunications, there are three things that are converging. The first one istext. The second is voice. And the third is the video. Text, voice and videoare converging together to form the world of communications over IP. VoIP isnow going to become CoIP.
In the world of CoIP, CoIP is going to use the same set ofprotocols that voice over IP used to use. One of them is SIP, which is the mostwidely used protocol and SIP stands for Session Initiation Protocol. The worldof voiceover IP also uses RTP in order to send the voiceover IP data. The worldof CoIP, or communications over IP, will continue to use RTP which stands forrealtime transport protocol.
CoIP is going to liberate what VoIP already has, andseamlessly extend the world of communications to various devices that includescell phones, PDAs, and the PC. The application that ties all of this together,the magical thread and the lynchpin of CoIP or communication over IP, isinstant messenger or IM; the application that ties the text, voice and videotogether and allows the users to seamlessly communicate on whatever device theywant, wherever they want, whether it be their cell phone, PDA, or the PC.
As a result, the future of voiceover IP becomes CoIP orcommunications over IP.
