A '''conference call''' (sometimes called an '''audio teleconference''' or '''ATC''') is a [[telephone call]] in which several people share a telephone line at the same time. The conference call may be designed to allow the [[called party]] to participate during the call or set up so that the called party merely listens into the call and cannot speak.

The more limited '''three-way calling''' is available (usually at an extra charge) on home or office phone lines. For a three-way call, the first called party is dialed. Then the [[hook flash]] button (or recall button) is pressed and the other [[called party]]'s phone number is dialed. While it is ringing, flash/recall is pressed again to connect the three people together. This option allows callers to add a second outgoing call to an already connected call.
