A conference call lets many people share a single telephone line at the same time. 
There are a few ways these calls work. One simple way is called three-way calling. First, two people make a normal phone call. Then, one person tells the other they will add a third person.

A conference call, also known as an audio teleconference, is a telephone call where several people share a single line at once. 
There are different ways to connect people for a call. One simple method is three-way calling, which is often available on home or office lines. First, two people establish a normal point-to-point call. One person then tells the other they will add a third person. They press a button called a hook flash or recall button and dial the third party. While the line is ringing, they press the flash or recall button again. This connects all three parties together immediately. This specific method does not require a separate conference server. Instead, all the mixing of the audio is handled within the endpoints, which are the phones themselves.
For larger groups, a more complex system is used involving a conference bridge. A conference bridge is a specialized type of equipment that links many telephone lines together. Many companies hire a service provider to maintain this bridge. These providers give participants specific telephone numbers and PIN codes to dial into the meeting. Some providers can even dial out to participants to introduce them to the group. An operator can also be summoned to the call using specific keys on a telephone keypad. The most common recall function for an operator is *0. These operators can manage the call by muting lines, muting specific participants, or enabling a recording feature.
Large public corporations in the United States use conference calls for a specific purpose called earnings calls. These calls are used to report quarterly results to stock analysts. A standard earnings call usually begins with a disclaimer. This statement explains that any spoken information may be a forward-looking statement and that actual results may vary. Then, the CEO, CFO, or an investor relations officer reads the company's quarterly report. Finally, the call is opened so that analysts can ask questions. This structured process allows many people to hear important financial data at the same time.
Modern technology has expanded how these calls work through web conferences. In a web conference, participants use the internet to share presentations or documents. This allows everyone to view corporate reports or sales figures while a presenter explains them. This combination of audio and visual data helps people understand complex information more clearly. However, users must be careful when mixing video and audio on the same network. A video feed can sometimes cause interruptions in the sound quality. Some conference calls are even used for podcasting or live streaming to reach huge audiences.
There are several ways to pay for these services. Flat-rate services offer unlimited access to a conference bridge for a fixed monthly cost. This is popular for budget-conscious businesses and non-profits. Prepaid services allow users to purchase conferencing online on a pay-as-you-go basis. After buying the service, the user receives a PIN and calling instructions via email. Free conferencing exists but works differently. In these cases, the company is often paid through a revenue-sharing arrangement with the local phone company. While free calls have no organizer fees, some customers claim they have more background noise than paid services. Premium-rate calls involve participants dialing a number like a toll-free number. The person hosting the call, such as a lawyer or educator, usually pays the cost.
Rules and laws also affect how these calls are billed. In the United States, the Federal Communications Commission (FCC) issued an order in 2011 regarding how carriers are compensated. This order changed how terminating access rates, which are fees for connecting calls, were handled. Between 2012 and 2017, these rates were reduced in increments until they reached $0. These small charges were replaced by an access recovery charge (ARC) on customer bills. In the United Kingdom, the rules for prefixes like 0870 have changed as well. In 2009, the regulator Ofcom removed certain rebates for these numbers. This led many providers to move to 0844 or 0871 prefixes to keep their revenue sharing. Recently, some UK providers have moved to 03 numbers, which are often included in standard phone minute bundles.
