How are people finding PhoneBridge?

I am trying to get PhoneBridge working with Twilio. 

One bug I've found on two different Mac computers is if you're not viewing your browser at the time of someone calling:
  1. You don't get any indication other than a phone call noise that a call is coming through (you'd think there would be a chrome alert like SalesIQ)
  2. You cannot answer the call - see screenshot below - these no number and no answer button
Has anyone else had these problems and overcome them? I'd love to use their integration but it really does suck at the moment... It has so much potential but I'm not sure if I can trust it.
