PIPELINEGuide
How long does an AI phone assistant take? Realistic timeline
An AI phone assistant project is not a weekend task, but not a six-month project either. What happens in what order, where bottlenecks typically occur, and how to shorten the timeline.
An AI phone assistant takes 2 to 3 weeks in practice. The biggest time factor is almost never the implementation itself, but how quickly content, access, and decisions come from your side.
01 — Timeframe
How long it takes
- Typical duration
- 2 to 3 weeks
- Price
- Individual based on effort
The timeline starts after approval of the quote. Lead time for initial meeting and quote: typically one to two weeks. We provide a fixed price after this initial meeting.
02 — Process
The steps in detail
Categorize calls
We review a week of your calls: what are people actually asking? This creates the guide.
Build conversation flow
Greeting, follow-up questions, appointment logic, emergency keywords. Everything is defined before a line of configuration is written.
Trial operation on secondary number
The assistant first runs in parallel on a second number. You listen in and make corrections.
Activation
Only when the conversations work does it switch to the main number — usually with a delay so you can answer first.
03 — Bottlenecks
What typically causes delays
- Content and deliveries. By far the most common cause of delay. Text, images, price lists, access credentials — what's missing blocks progress.
- Decisions. When it's unclear who approves, the project waits. A named contact person with decision-making authority noticeably shortens the timeline.
- Access to third-party systems. Getting access to inventory management, phone systems, or CRM regularly takes longer than the integration itself.
- Endless review rounds. Two correction rounds are normal, five are a sign that the goal wasn't clear at the start.
04 — 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
05 — 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.
Does the assistant understand dialect?
Austrian standard German and moderate dialect reliably, heavy dialect not always. That's why we build in follow-up questions: when unclear, the assistant asks rather than guessing. Critical information like phone numbers is repeated for confirmation.
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.
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.
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.
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.
