Depending on the type of phone a user has, call back when free is accessed by dialing a short code while listening to internal busy tone, selecting an option from an interactive menu or pressing a programmed DSS/BLF key. Callback when free can also be activated from Phone Manager. You can also set a callback when free or a callback when next used using a short code without attempting a call. In use, it allows IP Office users to carry on with other work and let the system initiate a call for you when the extension becomes available.

• When calling an extension that is busy, set the system to call you when the extension becomes free. This feature is also called "Ringback When Free".
• When calling an extension that just rings, set the system to call you when the extension is next used. This feature is also called "Ringback When Next Used".
