The problem

Appointment businesses miss calls when they’re busiest — mid-treatment, mid-cut, mid-service. Most callers don’t leave a voicemail. They ring the next clinic on the list.

What it does

6 things Relay does properly

Answers as you

Missed calls divert to Relay. It greets callers with your business name, says it’s an AI assistant, and speaks British English with dates the way people say them: “Tuesday the 28th of July”.

Only your facts

Prices, treatments, opening times and policies come only from your knowledge base or live tools. If the answer isn’t there, it takes a message instead of guessing.

Books, moves and cancels

A request-and-confirm loop: the booking is written down and confirmed before the caller is told it’s done. A booking that isn’t recorded didn’t happen.

Straight to WhatsApp

Every outcome reaches the owner’s WhatsApp within seconds, with one-tap approval where needed. Callers get their confirmation and a reminder the same way.

Safety first

A fixed triage check runs before the AI on every caller turn, so urgent medical situations are routed to 999 or 111 without depending on a model’s judgement.

Fails into human hands

If anything in the voice pipeline fails, the call still ends in a voicemail and a WhatsApp alert. A perfect message beats a gambled answer.

Quality bars

Rules it doesn’t break.

01Fast enough to feel human: Target under 800 ms from the caller finishing to Relay speaking.
02Never invents facts: Clinical content, prices and availability only ever come from tools or your knowledge base.
03Finishes the booking: End-to-end: recorded, confirmed, and on the owner’s phone.
04Tested like it matters: Scripted caller scenarios — bookings, reschedules, prices, emergencies, attempts to mislead it — run on every change.
