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; the fonio number you cancel. 3. Greeting, voice, test call Write the greeting, choose a voice, call yourself. Until the fonio term ends both run in parallel; one number can only go to one assistant, and you decide which. ## Common questions **What does fonio.ai cost?** According to its pricing page in September 2026: Solo €119 a month or €99 on annual billing, with 1,000 minutes and one number; a further 100 minutes €15, each further number €7 a month.

In return terminio gives you the booking page, calendar, WhatsApp reminders and team in the same price, and an assistant that books into exactly that calendar. Reckon with your minute demand: under 200 minutes a month the calendar counts, above it the minutes do. **Does fonio.ai book appointments straight into the calendar?** Through integrations: the website names Calendly, HubSpot, Salesforce and API interfaces.

Beyond that every minute costs €0.25; at 300 minutes that is €25 more. Whoever regularly needs 500 minutes and more is cheaper off at fonio.ai and should know it. **Can I use fonio.ai and terminio.ai in parallel?** Yes, until the fonio term ends for example, or if fonio should handle the hotline and terminio the bookings. Every number goes to one assistant; you forward the booking number to terminio and leave the other where it is. --- terminio.ai is online appointment booking for small businesses with WhatsApp reminders and an AI phone assistant, from €0 a month, hosted in the EU.
