AI phone assistant: process, approach and what's needed from you

The process for AI phone assistants from the first question to live operation — including what you need to contribute to make it work.

Quote on request2 to 3 weeksAs of 2026
In short

An AI phone assistant project runs in 4 steps: from “categorize calls” to “activation”, 2 to 3 weeks total. Each step ends with a clear approval before the next begins.

01 — Process

The steps in detail

  1. Categorize calls

    We review a week of your calls: what are people actually asking? This creates the guide.

  2. Build conversation flow

    Greeting, follow-up questions, appointment logic, emergency keywords. Everything is defined before a line of configuration is written.

  3. Trial operation on secondary number

    The assistant first runs in parallel on a second number. You listen in and make corrections.

  4. Activation

    Only when the conversations work does it switch to the main number — usually with a delay so you can answer first.

02 — Participation

What we need from you

  • A contact person who can make decisions — not just forward them.
  • Access to the affected systems, in time and not on launch day.
  • Real examples from daily business — the messier, the more useful for testing.
  • Two to four hours for coordination, distributed over the project duration.
  • An answer to the question of what success means. Without it, nothing can be assessed afterward.

03 — Scope

What's included

  • Conversation guide for your most common requests, developed together
  • Appointment scheduling directly in your calendar, including buffer times and blocked times
  • Transfer to a real person for urgent matters or clear keywords
  • Log of every conversation via email, with recording and transcript on request
  • Own phone number or activation on your existing number on no answer
  • Announcement text and voice tailored to your business, with dialect coloring on request

04 — Questions

Frequently asked questions

What happens in an emergency?

You define keywords — for an installation business, for example, “water damage” or “no hot water”. When these come up, the call is immediately transferred or a number is called, instead of writing a log.

What does a missed call actually cost us?

You can calculate it: average order value times closing rate times missed calls. For trades businesses with an average order value of 800 euros, one additional job won per month is enough to cover the costs.

Can it run only in the evenings and on weekends?

Yes. Many businesses activate the assistant only outside office hours and when the line is busy. That's the most affordable option and still covers the majority of lost calls.

How long until it's good?

After the trial phase, standard cases are handled. The fine points — rare requests, unusual phrasings — are added in the first four to six weeks.

Can it enter appointments in our calendar?

Yes, in Google Calendar, Microsoft 365 and common industry calendars. You set available slots, buffer times and blocked times, the assistant only books within these rules.

Do we need a new phone system?

No. In most cases, call forwarding on no answer is sufficient. If you have a cloud phone system, it's even more direct.

Do callers notice they're speaking with an AI?

Yes, and that's how it should be. The assistant says at the beginning that it's a digital assistant — the EU AI Act has required this since August 2026 and it prevents trouble. In practice, hardly anyone minds as long as their request is handled.

05 — Decision

How to move forward

The most affordable next step is a conversation, not a quote. Twenty minutes is usually enough to clarify whether a project makes sense, what scope it involves, and whether we're the right fit.

If we're not, we'll say so. An honest no costs less than a project you abandon after three months — for both sides.
