AI phone answering for UK businesses, priced in pounds.
Stop sending callers to voicemail. Heavano answers your line on the first ring, handles the routine calls end to end and passes the rest to your team — with per-second billing in GBP and no monthly subscription.
What is an AI phone answering service?
An AI phone answering service uses a voice agent instead of a person or a call centre to answer your business calls. It handles common requests — questions, bookings, messages — in natural conversation at any hour, and transfers to your team when a human is needed, so no call goes unanswered.
