The future of VoIP: CoIP
Madhu Yarlagadda from Yahoo says that text, voice and video are converging over the same set of protocols used by VoIP and that Instant Messenger will be the application that enables users to seamlessly move between them -- creating 'CoIP', communications over IP.
I'm Madhu Yarlagadda, Director, Real Time Communications at Yahoo! In my last Whiteboard I talked about voice over IP being ready for primetime. In this session, I'm going to talk about the future of voice over IP, what I call it CoIP. CoIP stands for communications over IP. In the world of communications, there are three things that are converging. The first one is text. The second is voice. And the third is the video. Text, voice and video are converging together to form the world of communications over IP. VoIP is now going to become CoIP.
In the world of CoIP, CoIP is going to use the same set of protocols that voice over IP used to use. One of them is SIP, which is the most widely used protocol and SIP stands for Session Initiation Protocol. The world of voiceover IP also uses RTP in order to send the voiceover IP data. The world of CoIP, or communications over IP, will continue to use RTP which stands for realtime transport protocol.
CoIP is going to liberate what VoIP already has, and seamlessly extend the world of communications to various devices that includes cell 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, is instant messenger or IM; the application that ties the text, voice and video together and allows the users to seamlessly communicate on whatever device they want, wherever they want, whether it be their cell phone, PDA, or the PC.
As a result, the future of voiceover IP becomes CoIP or communications over IP.
