  • Each participant in the conference call is provided with, typically, a telephone number to access the conference call service and a password or identification number that must be entered before they can join the conference call.
  • the administrator first dials in to the conference call service to set up the conference call.
  • the conference call is provided using a conference bridge, which links telephone lines. Once the administrator has initiated the conference call, the other participants can then dial the provided number, enter their password or identification number, and access the conference call.

In this way, participants are added to the conference call. Using this model, the administrator is typically charged for the call to each participant.
  • Conference calls can be complicated for residential users to set up and handle, and not something that a residential user would normally set up or join.
