the Fonality HUD makes your phone system literally drag and drop. Want to call someone? Drag their name to your name or vice versa. Want to transfer a call? Drag your name (which shows you're on a call) to someone else's name.
We have admin assistants who still go through the old PBX extension dialing, or the press-the-transfer-button, say-an-incantation, dial-another-person's-extension, and-sacrifice-a-virgin process. Misdials all the time.
