Three steps to a booked appointment
A call comes in
Your customers call your existing number as usual. You answer whenever you can – only when no one picks up (busy, peak time, after hours) does Terminstimme step in automatically after a few seconds. Your number stays the same.
A natural conversation
The assistant greets the caller, understands their request and answers questions about services and opening hours – in fluent, natural language. It recognises emergencies and forwards them to you.
Booked & confirmed
Available slots are checked in real time, the appointment lands straight in your calendar – and your customer automatically receives an SMS confirmation.
Tailored to your business – without you touching any tech.
Terminstimme isn’t a self-service software subscription. No account, no login, no calendar you have to connect yourself. We set the phone assistant up completely for you – tailored to your services, your opening hours and the way you speak. You focus on your trade, we handle every technical detail.
What we take care of
- Bespoke setup – tailored to your business
- Connecting your calendar – we do it for you

Hear it for yourself.
The most convincing thing is simply to call. On our demo number, Terminstimme answers as the assistant of a fictitious example trade business – no sign-up needed.

What you should know
Can the assistant tell recurring from one-off cleans?
Yes. It asks about the request and books accordingly – from a maintenance contract to a one-off deep clean.
Is the assistant reachable outside office hours?
Yes. Terminstimme takes calls 24/7 – so short-notice special cleans in particular don't get lost.
Does my existing phone number stay the same?
Yes. Terminstimme is integrated via overflow on your existing number – your customers keep dialling the same number. On request, we'll also set up a dedicated appointment number.
Can I try Terminstimme without risk?
Yes – there is no setup fee and no minimum term. You see from real numbers in the monthly report how many calls would otherwise have been lost, and can cancel at the end of any month.
