Warnings
- You will pay for conference calls the same amount that you used to spend for domestic and international calls.
- You could pay taxes if you do a three-way conference on a landline, especially when you haven't subscribed to a plan that includes several phone services, including three-way calling. Check with your local telephone company.
- If you are the initiator of the conference, be aware that you are the one who will have to pay the costs associated with each call. If one of your callers added another person to the conference, they will pay the fees for that person.
