If you are away from your computer or have a slow wi-fi connection, you can dial in to the meeting. Dial one of the phone numbers from the invitation, and when prompted, enter the conference ID followed by the pound (#) key.
If you are the host of the meeting and dial in, enter the conference ID followed by your 4-digit host code (PIN), and then press the pound (#) key. This identifies you as the meeting host. Do not use the mobile one-click numbers because you can’t enter your host code.
On a mobile device? Tap one of the one-click numbers in the invitation. This connects you to the meeting without having to enter the passcode (conference ID).
