Question

How do you make a three way phone call?

Answer 1

If you want to make a three way phone call, call the first person, then press flash (on home phones), TRANSFER/CONFERENCE (on some work phones) or the green call button (on cell phones), then dial the second person, then press the first button again and you'll have a three way conversation!

Answer 2

It will depend on which country you live in and which company provides the service. In the UK it is an extra service which they can provide and you pay for, when you get the service you will get the instructions as to how to operate it.
