Large companies who handle a lot of call volume, like cable and credit cards, have had IVR systems with that capability for years, but now, with Twilio, it's so much easier and cheaper. Two things you've said or done, that have really made Twilio click for me are: 1) It brings smart-phone web capabilities to every simple voice phone. 2) As a dev, your appointment reminder demo just slaps me in the face with the concept that a phone call and web session can essentially share the same session id.
