Generally, two methods are used to set up a teleconference. In the dial-in method, the conference participants call a previously notified conference number at an agreed time. In the dial-out method, the teleconference participants are called and connected to each other. Depending on the underlying tariff model, the caller, the called or the organiser of the conference bear the costs partly or completely.
Generally, the following features are provided as basic functions during a conference call:
- Adding more participants
- Protecting the conference with a PIN
- Playing recorded messages
- Allocating moderator function
