voiceOne or terminio.ai? What sits behind “from €29”, what terminio Pro Voice includes for €129.99, and which AI phone assistant fits a salon, studio or practice. Honest, with sources.

As of September 2026 · Sources: voiceOne's website, third-party sources (telefon.services, May 2026)

## Verdict

- voiceOne fits if … you want to start at the lowest entry price, your calendar lives in Google, Microsoft 365 or practice software, many languages and many parallel calls matter, and you are happy to put the package together in a call.
- terminio.ai fits if … you want to know the final price up front and the assistant should book into the same calendar as your booking page, with a WhatsApp confirmation afterwards, without a second tool.
- The biggest difference An entry price against a final price. “From €29” without minutes or a number against €129.99 with number, 200 minutes, calendar, booking page and WhatsApp.

## Prices

- terminio.ai: €129.99 a month · number and 200 minutes included · then €0.25 per minute · booking page, calendar and WhatsApp in the plan · cancel monthly
- voiceOne: from €29 a month · packages are put together individually · included minutes and number not named on the website · free trial without a credit card · cancel monthly per website

## Honestly

voiceOne:
- The start is cheaper: from €29 a month, free trial without a credit card, set up in minutes.
- Integrations with Google Calendar, Microsoft 365, CRM and practice software, up to HL7/FHIR; up to 60 parallel calls.
- Many languages at no surcharge, servers in Germany, on-premises on request for larger organisations.

terminio.ai:
- The price is on the pricing page with everything in it: number, 200 minutes, €0.25 per further minute. No package call.
- Books live into its own calendar, the same one as the booking page and the team, with a duration per service and the requested person; WhatsApp confirmation and reminder run along.
- One plan for a salon, studio or practice instead of three tools: booking page, calendar, reminders and phone from one app.

## Switching

1. Set up services and hours Tap your industry, check the services with duration and price, set opening hours. The assistant books only what is really free in the calendar and says only what you entered.
2. Number and forwarding terminio gives you a German phone number. You forward: always, only when nobody picks up, or outside opening hours. Your existing number stays as it is.
3. Greeting, voice, test call Write the greeting, choose a voice, call yourself. voiceOne runs in parallel until you cancel; one number only goes to one assistant, and you decide which.

## Common questions

**What does voiceOne cost?** The website says “from €29 a month” and offers a free trial without a credit card; packages are put together individually according to the website. How many minutes are in the price, whether a number is included and what a further minute costs is not public, which is why our table shows question marks. The final price for your business comes in a call.

**Is voiceOne cheaper than terminio.ai?** At the entry, yes: €29 against €129.99. Whether that holds for the final price depends on what your package contains. At terminio the number, 200 minutes, booking page, calendar and WhatsApp reminders are in the price. After your call with voiceOne, compare the two final prices, not the entry prices.

**Does voiceOne book appointments straight into the calendar?** Through integrations: the website names Google Calendar, Microsoft 365, CRM and practice software; the calendar stays your own tool. terminio.ai has the calendar itself, knows the duration and price of every service and the hours of every person, and the booking page shows the same free slots as the assistant.

**Where is call data stored at voiceOne?** According to the website on servers in Germany, GDPR compliant, on-premises for larger customers. terminio.ai is hosted in the EU and stores name, mobile number and appointment.

**What if I only want the phone and no booking page?** Then be honest with the sums: terminio Pro Voice includes the booking page and WhatsApp whether you use them or not. If you really only need a call answerer for someone else's calendar, voiceOne or fonio.ai are cut closer to that. If you hand out appointments, you usually use the booking page within a week.

**Can I test voiceOne and terminio.ai in parallel?** Yes. voiceOne offers a free trial; terminio Pro Voice starts without one but can be cancelled monthly with no setup fee. Forward the number to one for a week and to the other for a week, and count what arrives in the calendar.
