With the Forward all site calls (FASC) feature, you can forward all incoming calls directed to a specific site within your organization to a phone number, a recorded message, or a voicemail. For example, a receptionist can enable FASC on the site main phone number to forward all incoming calls to a predefined greeting during a holiday or an emergency. Your server administrator can configure multiple FASC buttons and define their corresponding destinations, and optionally configure FASC buttons on your phone screen. Contact your server administrator for details about the FASC buttons and destinations.
