When you sign-up a free primary dial-in is assigned to your account based on your location. You can change your default primary dial-in to any of the 15 available free dial-ins from your account settings.
If you subscribe to any of the paid plans, additional premium dial-ins are available with brand-free greetings, including toll-free numbers. Any of these dial-ins can also be assigned as your primary dial-in.
All dial-ins associated with your plan can be used for any conference call. The choice is yours (and your participants’). No matter what dial-in people use, you will all be connected to the same call using your moderator PIN and access code.
