I think it's not going well? I keep getting to the start a new call page, it fails, and takes me back to the live page. I assume your servers are on fire, but implementing some messaging would help ("come back later") or even better, a queueing system ("you're N in line") would help a lot.

Really looking forward to trying this out!

We're back online! One of our cache systems ran out of memory. Oops. Agree on improved messaging.
