AOL is the king of instant messaging (IM) and a cross-platform solution (but proprietary OSCAR protocol) but is doing little with true Voice over Internet Protocol (VoIP). Apple has iChatAV with voice, video and IM (on Mac’s only but interoperates over OSCAR with others). Yahoo buys Dialpad to add voice to their IM capability (on the PC only). Google Talk debuts with voice (IM cross platform but voice on the PC only) and now our pals in Redmond pull-the-trigger and buy Teleos to add voice to *their* IM client (and I’ll bet it’s PC only).
Then you’ve got new VoIP vendors like Packet8 and Vonage…as well as VoIP offerings from the cable companies and traditional telephony providers…all scrambling to get in the VoIP game with their own products. Oh yeah…then you have the open Session Initiation Protocol (SIP) which purports to be a rapidly accelerating VoIP standard protocol. The intent of SIP is to enable providers to write their software to a common protocol so that all VoIP telephony products can interoperate vs. going off and building proprietary protocols with the primary intent to capture customers (a good example of a computer-based SIP offering is the Gizmo project).
So what’s up with these moves in to voice? Who is going to end up at the top of the pyramid?
