I scheduled a Google Hangout from Google Calendar (under my personal Gmail account). I'd like to have a way for participants to join it by phone only - either them dialing in or me dialing out to them.
How can I do this? I tried installing the UberConference Google Hangouts app, but when I open it, I just see a panel saying that it is loading (have not been able to get it to load).
I saw this support article, but I do not see a "call tab" as described.
