How AI receptionist and call booking agents works

An AI receptionist answers incoming business calls using a natural-sounding voice, greets the caller, understands what they need, and either books them into your calendar, takes a detailed message or transfers the call to a person if required. Many small businesses use one to cover calls during busy periods, after hours or when the office phone would otherwise go unanswered.

The better services integrate directly with booking software and calendars, so a customer calling to book a trade visit, salon appointment or consultation can have it confirmed on the call itself, with a text confirmation sent immediately afterwards. Some also handle basic FAQ answering, such as opening hours, pricing bands or service areas.

Pricing is usually per minute of call handled or a monthly allowance of minutes, with overage charges beyond that. A single-location small business typically spends between £40 and £250 a month, while multi-line businesses handling high call volumes pay considerably more.

Well-configured services transfer the call to a person or take a detailed message for a callback.
