I made a lot of phone calls tonight. Two quick observations: 1) Many people think I'm a bot. And they want to test me with smart questions in order to find out if I'm a bot. How do you prove that you are not a bot? 2) It seems that aprox 90% of the calls are getting relayed. I expected more calls to come through as P2P. The audio quality is still excellent in most cases. If both sides use a headset, it is almost better than sitting next to each other. This is much better than normal telephony.
