Really cool!<p>The part I find the most interesting is that you can separate SMS and voice services on 800 numbers (like leave your crazy Verizon TollFree rate intact and do your SMS through Twilio). Very interested in how that's happening.<p>I assume Twilio contracted with Syniverse as a TollFree SMS manager, but I'm very curious how they can send and receive SMS on numbers they don't own. I would hazard a guess that Twilio has gotten a contract with Syniverse, the first of its kind, that decouples voice and SMS from toll free.<p>Crazy times these, way cool feature!
