Conference calls: everything you need to know about modern conference calls

Conference calls have become an essential tool for businesses that want to communicate quickly, efficiently and without geographical constraints. Thanks to the democratisation of VoIP, collaborative applications and videoconferencing solutions, it is now possible to bring together teams located anywhere in the world in a matter of seconds, from a computer, smartphone or landline.

This simple, fast and economical format makes it possible to organise remote meetings, lead team discussions, present projects or even train large numbers of participants. It is a communication solution that has become essential in today's professional environment. Platforms such as Imagina fit perfectly into this approach by offering reliable, interactive and easy-to-use audio/video tools.

Conference call: clear and accessible definition

A conference call is an audio and sometimes video exchange that brings together several people simultaneously via a connected device:

• landline telephone,
  
  
• mobile phone,
  
  
• computer,
  
  
• tablet.
  
  

It can be carried out via the traditional telephone network or via the Internet using VoIP technology. Modern conference calls are no longer limited to audio: they often include screen sharing, video, microphone management, participant visualisation and even interactive tools.

They can be used in a fully equipped meeting room (telephone ‘octopus’, HD screens, etc.) or entirely remotely via a digital solution.

Audio, video, VoIP: the different types of conference calls

1. Audio conferencing

The simplest version: several participants dial into a dedicated number and communicate solely by voice. Ideal for quick meetings, progress updates and confidential discussions.

2. Video conferencing

A direct evolution of conference calls, video conferencing adds video, screen sharing and sometimes reactions or comments. It is now the most widely used format for team meetings, webinars and training sessions.

3. Web conferences

These combine audio, video, chat, presentations and collaborative tools. This is the most comprehensive format for organising structured remote meetings.

4. Hybrid solutions

Some conference calls combine participants in a room with others who are remote. VoIP equipment and connected speakers facilitate this configuration.

How does a conference call work?

The principle is simple:

1. an organiser creates the meeting,
   
   
2. shares a link or access number,
   
   
3. participants join the conference from their device,
   
   
4. and the conversation takes place via audio or video.
   
   

Thanks to the internet, VoIP offers excellent sound quality, enhanced stability and advanced features (microphone management, participant list, screen sharing, etc.).

Each solution on the market has its own specific features, but they are all intuitive and accessible, even for non-technical users.

Platforms such as Imagina integrate these features into a clear and fluid interface designed for events and professional use.
