When you turn this on and start a multiline dialing session, this will add an interactive voice response (IVR) for call recipients. After callback messages, prompting “Press 1 to opt-out of further communication”.
If one of your call recipients does opt-out from you contacting them again. They will be placed on your Do Not Contact (DNC) list. You may also manually add numbers to your DNC List to avoid contacting them in the future (see DNC List for more details).
