How do I set up conference calling?

It's free to join a conference call – you'll only be charged if you start it. You're charged for the number of people you invite to join the call. For example, if you set up a call lasting 15 minutes with 2 other people, you'll be charged for 30 minutes.

Like any other call, the minutes you use for your conference call will come out of your allowance.

You can speak to up to six people at once on a conference call.
