All 297 of Hull's telephone boxes will ring at the same time today.
The event marks the start of the fourth and final season of Hull's City of Culture year - called Tell The World.
Anyone who answers the call at 2pm will be able to have a conversation with someone from the year 2097.
Nick Tandavanitj is from Blast Theory.
He says: "If you pick up the call that really is the start of the journey. So a lucky few people that answer the call will also be invited to meet characters from the future and take a ride in a Tesla electric car."
