  2. The meeting organizer will have to allow you to join the meeting.

Tips on dialing-in

  • Enter the dial-in number for the country the team was created in. Each country has its own number. If you’re in a different country, you will not use the number for your country. Instead, you must use the number for the country the meeting/team is in.
  • If you’re in the same country as the team/meeting, you can skip adding the country code.
  • You should enter the city code when dialing in.
  • Some teams set up a different phone number. If so, confirm with the meeting organizer which number to use to dial-in.


Dialing in seems complicated but you will find that it is easy to do once you have the conference ID. Each meeting has its own unique conference ID. The dial-in number may or may not be toll-free. It depends on the country and the team settings. If you plan on dialing into a meeting, check if you will be charged for the call before you enter it.
