voiceOne
In short
In 30 seconds.
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.
Features
Point by point.
Eleven rows that count for a phone assistant: does it book, is the number included, how many minutes, what does it need around it. Whatever voiceOne does not say publicly stays a question mark and never counts as a no.

HonestlyWhere voiceOne is stronger.
Where voiceOne is stronger.
Where terminio is.
voiceOne

- 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.
For whom
Typical in these industries.
voiceOne has pages of its own for hairdressers, beauty salons, nail salons, physiotherapy and practices. Exactly there terminio.ai has a page of its own about the phone assistant, with the trade's own workflows.
SwitchingFrom voiceOne to terminio
From voiceOne to terminio
in three steps.
- 01
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.
- 02
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.
- 03
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.

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.
