The Call for Participation for our next Emerging Telephony conference is now open. This is my favorite conference of the year, and not just because I work for O’Reilly. ETel has become a showcase for the most interesting and innovative things happening in telecommunications. We welcome plenary submissions for our audience of people who, like you, are pushing through the boundaries of communications into new ways of thinking and doing. Topics will be centered around the innovations and projects occurring at the intersection of voice, instant messaging, the mobile ecosystem, and the Web. ETel will be held March 3-4 in San Diego, California. The deadline to submit a proposal to speak at ETel is September 17, 2007.
