If you want to join the call the dial in instructions are below. If you have something to say after dialing in then when I call out your username (if you sign up for an account) or the first 7 digits of your phone number chime up. I go through the list of callers FIFO and give everyone a couple minutes to have their say. If you just want to listen then no problem there, just please self-mute your mic.
You'll need a headset with a mic to talk (but not listen) if you don't dial in via land line (see below).
