Everybody's seen the demo: you call a number, an AI picks up, and you can suggest to hand over you to a real person.

It answers a real phone number, talks back in whatever language you speak to it, looks up answers to your questions, and hands you off to a real person when you ask.

Picture a few characters and a middleman.

The caller: a human on a phone.

The phone system: the thing that actually answers the call. (We used FreeSWITCH, a free, open-source phone server.)
