Instant Conference Calls

United Conferencing uses instant conferencing technology. You do not need to register with us, or schedule a call ahead of time. Simply choose an access code, send it to your participants, and all call in at the same time.

Having a recurring call? Our system handles that too. Just use the same access code every time you need to have a conference call.

How To Host An Instant Conference Call

  • Choose a six digit access code, i.e. 498466. Do not use an obvious number string like 111111.
  • Share the access code and dial in phone numbers with all the participants on your conference call.
  • Have everyone dial in to the conference service and enter their access code at any time. Press # after you enter the access code.
  • We’ll place everyone into the conference room.

Call From 30 Countries

United Conferencing offers international conference call access numbers in 30 countries. All of these access numbers connect to the same conference bridge so that you can host an international conference call with local dial in access numbers.
