Once you log in to your account, you’ll see a dropdown menu under your user profile name in the upper-right corner. Select Dial-in Numbers, and you’ll be shown all available countries and dial-in options. You can copy and paste these numbers directly into your invitations.
These dial-in numbers are also available through our integration tools, including the Office 365 Add-in, Outlook Plug-in and Google Calendar Chrome Extension, to make sending invitations even easier.
