How Do conference calls work

A conference call is a phone call that includes numerous participants. People invited to the meeting can participate in a teleconference by dialing a number that connects them to a conference bridge. These conference bridges serve as virtual rooms, allowing multiple participants to host or attend meetings.

Today, it is more customary to hold conference calls online. However, if you do not have internet access, you can still do it via a phone.

What are the requirements for starting a teleconference?


The most important requirements for participating in a conference call are the following:

Dial in number
Access and PIN codes

You will need these numbers whether you hold your meeting online or over the phone. There are a few providers who offer conference services without access or PIN codes, but most require them for enhanced protection.

Dialing numbers

A dial-in number is the phone number that participants must dial to join a conference call. These numbers are provided to you by your service provider. You can also acquire a dedicated dial-in number, which is linked to your own account.

With a dedicated dial-in number, you won't have to share conference lines, eliminating the requirement to make a reservation before conducting a meeting. This implies you will be able to teleconference at any moment.

Toll versus toll-free numbers

Dial-in numbers are either toll or free. If participants phone a toll number, they will be charged call fees. If the dial-in number is toll-free, the host is responsible for paying the call fees.

Local versus international numbers

Participants can participate in conference calls from anywhere in the world. To make a local call, all you need is the phone number and the access codes. Take note of whether the number is toll or toll-free to avoid any unexpected charges on your bill.

If you're calling abroad, you must provide a country code at the beginning of the number you're dialing. Each country has a unique code, so make sure you know which one you'll need for your meeting. The dial-in number is usually followed by the country code, which is stated in parentheses.

Access codes

In addition to the dial-in number, you will be given an access code to enter while joining a teleconference. Access codes are typically seven symbols, and if you are the host, you must transmit the code to the meeting attendees.

PIN Codes

Access codes, usually known as PIN codes, serve the same purpose. However, for the majority of services, the host initiates the conference using PIN codes. This also gives them access to advanced features such as conference lock, recording, caller count, and more.



Operator-assisted

An operator-assisted conference call, as the name implies, has an operator on the line to help facilitate the meeting. These teleconferences are often more expensive than reservationless options.

However, the benefit of an operator-assisted conference is that you can delegate minor duties to the operator, allowing you to focus solely on the discussion. For example, they can record each incoming call and dial-in participant for you. They can also record the call and provide thorough transcripts after it's completed.

Aside from being more expensive, one significant disadvantage of depending on operator-assisted conferences is that you must make a reservation before you can schedule a meeting. This implies you cannot hold short, spontaneous meetings with your team.

Reservationless

In contrast to the operator-assisted option, reservationless conference calls are not handled by an operator. Instead, the host facilitates the call.

The key benefit of reservationless conference calls is that you may schedule a meeting without needing to book a conference line. You have a dedicated line that you can use whenever you want to host a meeting.

Reservationless services are more widely used than operator-assisted ones since they are typically less expensive. Furthermore, they provide meeting organizers with greater control over the conference's agenda and flow.
