What are Press 1 Voice Campaigns?

Imagine with us for a second: You get a call from your favorite restaurant telling you about an upcoming holiday special. If you’ve ever gotten a call like that — 1 for English, to change your appointment, to get a limited time coupon—you already know what a voice broadcasting press 1 voice campaign is! Press 1 to continue and hear more about how to book a reservation.

Press 1 voice campaigns are calling campaigns where people press the number 1 on their phones to interact with the campaign. By pressing a digit, people can take advantage of the offer, transfer their call to a live agent, or leave a message for the business that sent out the campaign.

How Press 1 Campaigns Work

Press 1 voice campaigns work by using an IVR phone system (interactive voice response). IVR is an over-the-phone menu system that prompts you to select certain digits based on a preset menu. Together, IVR and press 1 campaigns route you based on the phone numbers you press in response to the call prompts. So basically, IVR is the system that press 1 autodialer campaigns use to direct you to your desired information or actions efficiently.
