Some of my colleagues hate Instant Messaging, viewing it as a diversion from business urgencies or strategically contemplative activities. I respect that, but I, and millions of others of enterprise and SOHO users, love IM for its back-channel conversational capabilities. That's why I believe eyeBeam, a SIP-(Session Initiation Protocol)-enabled, VoIP softphone made by Xten, will take off. At the CTIA show this week, Xten has been working with Vonage to demonstrate eyeBeam's compatibility with Microsoft Windows Messenger. The phones use open standards such as SIMPLE SIP for Instant Messaging and Presence Leveraging Extensions and XCAP (XML Configuration Access Protocol) meaning that the devices will be easier to customize to your specs.
