I have a hypothesis that mobile VOIP over WiFi will replace mobile carriers for the majority of phone conversations within 5 years. For a reality check, I called up Justin Grammens of Localtone Interactive and Mobile Twin Cities.

From the picture he paints, I think we’ll see this well within 5 years. Maybe 2.

Projects and people we reference:
• Asterisk
• TrixBox
• Adhearsion
• Captain Crunch
• FreeSWITCH
• Twin Cities Asterisk Users Group
• Fring
• Hot, Flat, and Crowded: Why We Need a Green Revolution–and How It Can Renew America by Thomas Friedman

I also share with you my strategy for developing in this new mobile, web-based application world.
