While talking to a customer you can schedule a time for LiveVox to contact them again using the Schedule Callback tool on the Agent Desktop. When enabled, it will show on the desktop while you are in "In Call" or "Wrap up" status and allow you to set a time (and optionally phone number) at which the customer would like a callback. The below links will give you more details on using this tool.

All scheduled callbacks will be presented for your preview before they are launched. For more information, see the Preview Dialing section.
