Automated phone assistant – no call goes unanswered.
Terminstimme is an automated AI phone assistant that answers your calls around the clock, responds to questions and books appointments straight into your calendar – in natural language, GDPR-compliant and without extra staff.
Free initial consultation · Up and running in 2 weeks max · No training required
Every missed call is missed revenue.
Line busy, after hours, peak times – whoever can't get through often doesn't call back, but calls a competitor instead. Terminstimme catches exactly these calls and turns them into booked appointments.

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.

A phone assistant that understands your trade
Every industry has its own calls, its own emergencies, its own missed revenue. See the typical problems for your trade – and calculate your loss.
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. Try it out and book a test appointment, for example for a heating service.
+49 9422 9203127Tip: just say „I'd like an appointment for a heating service“ – the business is fictitious, no real appointments are created.

What you should know
Does Terminstimme replace my staff?
No. Terminstimme mainly catches the calls that would otherwise be lost – when the line's busy, after hours or at peak times. Your team is relieved, not replaced.
What does the assistant sound like?
Natural and fluent, in a real-time dialogue. Best to see for yourself and call our demo number.
What about data protection?
Processing takes place on servers in the EU, with a data processing agreement under Art. 28 GDPR on request. Details are in our privacy policy.
How quickly can I be up and running?
Usually within two weeks at most. No new hardware is needed – your existing number is integrated via overflow, or you get your own dedicated appointment number.
What happens if the assistant doesn't know the answer?
In such cases the call can be forwarded to your team or a call-back can be noted – entirely to your specifications.
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.
I already have an answering machine or phone service.
An answering machine doesn't book an appointment and doesn't recognise an emergency. An external phone service doesn't know your business and charges per call. Terminstimme knows your services and books straight into your calendar.
Which calendar does it book into?
Into your existing calendar – for example Google Calendar or Outlook. Double bookings are avoided.
Can I try Terminstimme without risk?
Yes – there is no minimum term. You start right away, 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.
