问题
I am trying out twilio using the quick start tutorial. I am doing browser to browser calls. I have followed the tutorial. When I try to make a call it rings and connects. It then plays the "free account" message and asks me to press any key to continue. When I press a key it does nothing for a few seconds and then hangs up without going through to the other browser.
Is this happening because I am on a free account or is there something else I need to do in order for it to register the key press from the browser?

I can see where this might be confusing and its good feedback. The prompt to press any key is apparently making the assumption that you are calling from an actual phone, which would include a keypad that lets you press any key. Obviously with a simple Twilio Client app there isn't by default a number pad to press, but the JavaScript SDK does include the sendDigits function, which makes it pretty trivial to wire up a button (or some other UI) in your app to send the equivalent of a key press (aka a DTMF tone) to Twilio.
Hope that helps.
