Good questions, straight answers

Enter your website address and your agent is trained in about three minutes — you can call it or talk to it in the browser right away. Your existing number stays the same, so your customers do not need a new one.

Yes — noticeably. With a FRITZ!Box, tellmachines connects directly to your box, and the connection works entirely without a new phone number: the agent answers on your existing line, like an additional handset that never misses a call. No forwarding setup, no number change, nothing your callers would notice.

Always. The standard route is call forwarding from your existing number to your included tellmachines number — always, when busy, or after a few rings. And with a FRITZ!Box you skip even that step.

That is your call, and we make the good choice easy: the welcome message is fully yours to write, and right next to the text field the editor reminds you to let the agent introduce itself as a digital assistant — for example "This is the digital assistant of Miller Plumbing". Under the EU AI Act, transparency towards callers is required; an honest introduction costs nothing, because the conversation quality speaks for itself.

It says so honestly — no invented answers. Depending on your setup it transfers the call to you live, or takes a callback request with a summary of what the caller needs.

Your caller decides. The agent speaks German, English and many other languages, and switches automatically mid-conversation when your caller does.

No — call audio is never recorded, and there is nothing to opt out of because it does not exist. You receive text transcripts and summaries, and you choose how long they are kept: from 1 to 400 days, or summaries only.

The tellmachines platform is hosted in Germany. For the AI conversation itself we use OpenAI as the speech model provider and Telnyx for telephony — we name our processors openly instead of hiding them. Details on the privacy & security page.

Usually yes — emergency routing, house rules, unusual booking flows. Write to us at info@tellmachines.com and we will talk through your setup together before you commit to anything.
