SEC 06 / STRAIGHT ANSWERS

Asked every week.

Will callers know it's AI?

Most never ask. It answers in your business name, in a natural voice, and gets on with taking the job. If someone asks outright, it's honest — then carries on booking them in. What matters to a caller with water coming through the ceiling is that someone picked up.

What happens to genuine emergencies?

They get put straight through to your mobile. You set the rules — what counts as an emergency and when you're willing to take the transfer. If you don't pick up, it takes the details and texts you immediately.

Do I have to change my phone number?

No. You keep your number. We use conditional call forwarding — if you don't answer within a few rings, the call comes to us. If you do answer, we never hear it.

How fast is setup?

Live within one working day of your test call. We build everything; you dial one forwarding code into your handset. That's the whole job.

What if it can't answer something?

It takes a message and texts you immediately. It never guesses prices and never promises work you haven't agreed to.

Is there a contract?

Monthly rolling. Cancel any time — no notice period, no exit fee. The setup fee is the only one-off.
