Not a Hotkey
This is not dialler agents hammering through data to find and persuade a customer to talk with your team.
Apart from the hotkey process being vulnerable to call centre agents cutting corners it is increasingly a compliance nightmare. Hotkeys are the past.
iCall is the future. This is a customer going online, learning about your product and then the customer picks up the phone and makes the call to your team, wanting to know more about your product.
