How to make a group call / conference call?

From your mobile application:

  • Call a first contact 
  • Once this contact has responded, several icons appear on the screen 
  • Click on the "+" icon (Add someone) 
  • The search for users starts: type the name of the person to be added to the conference 
  • Click on the name of the person in question: the call is launched
  • There are now two calls in parallel, on the screen two new icons appear: "Switch" and "Conference"
  • Click on "Conference", your two interlocutors are now on the same communication channel
  • Repeat the operation for each new person you wish to invite into the audio conference.

Each person on the call can add another person. 
However, it is not recommended to exceed the number of 5 participants in a group call/conference call.
