You can call into a meeting using any of Calliflowers international dial-in numbers, found here.
You can also add a toll-free number to your account for a small additional charge, that you and your participants can use when dialing in by phone.
To call in, you will need your PIN or Conference Code. This information is found in multiple places, for your convenience. It is located in the green menu bar near the top of the web dashboard, in your profile and in the Call Now overlay when you press the 'Call' icon. Remember, for any call, never share your PIN. It is unique to you and will cause technical issues if shared with other accounts.
