Objective: Hotel Arena is a four-star hotel with a restaurant, bar and nightclub in Amsterdam. Hotel Arena asked us for a creative concept to increase bookings and generate PR.Strategy/Concept: We simply made it easier for people to book a reservation, by making a radio spot that not only invites people to Hotel Arena, but actually dials the phone number for the listener. This works by broadcasting DTMF tones. The listener simply has to put their phone to the speaker. The DTMF string actually ‘dials’ the phone.

DTMF technology is available to everybody. Google ‘DTMF generator’ and try for yourself!
