Actually, there is a campaign feature that can do this:
Scheduled Callbacks Force Dial -
This feature will force an agent to a paused state and block out their screen with the next triggered USERONLY scheduled callback to be called. The agent's only option will be to dial this callback, although they are able to look at lead info before they do that. If there are multiple triggered scheduled callbacks for the agent, they all must be called before the agent can move on to handling other items. This feature will not pay attention to the Call Time that is set for the campaign, so these calls may be dialed outside of the set call time. The agent must be able to place manual dial calls for this feature to work. Default is N for disabled.
