Review your call use case Send an email

An AI phone assistant is a voice AI that answers or places calls on its own. It understands requests in natural language, books appointments, answers questions, qualifies leads and hands off cleanly to the CRM. Inbound answers every call, outbound runs follow-up and sales calls, GDPR-aware with servers in Germany or the EU. Automated advertising calls need the prior express consent of the person called, also in B2B (§ 7 (2) no. 3 UWG).

Process

How an AI phone assistant works

Technically an AI phone assistant combines three building blocks. Speech recognition turns the spoken words into text. A language model understands the intent, decides on the next action and formulates a reply. Speech output speaks that reply in a natural voice. In between sits the integration with your systems, so the assistant can book appointments, update contacts and file call notes. The flow happens in real time so the conversation feels fluid and the caller experiences no disruptive pauses.

Inbound

Inbound and outbound

An AI phone assistant works in two directions. In inbound it answers incoming calls, handles questions, books appointments and forwards complex cases to a human. In outbound it calls actively, qualifies leads, follows up and reactivates contacts. Both modes share the same technology but pursue different goals. Inbound makes sure no call is lost. Outbound makes sure no lead is left behind.

In detail

What an AI phone assistant can and cannot do

It can solve standard requests reliably, be available around the clock, book appointments and qualify leads. It can speak several languages and appear in your tone. It cannot replace human relationships, run sensitive negotiations or catch emotional edge cases like an experienced employee. That is exactly what clear handoff rules are for. The assistant handles the bulk of predictable calls, the human stays responsible for the exceptions.

Use cases

Typical fields of use

AI phone assistants are especially valuable where there is a lot of phone traffic and calls are easily lost. Medical practices relieve the phone despite a full waiting room. Trade businesses capture quote requests from the site. Law firms record client requests in a structured way. Real estate offices coordinate viewings. Sales teams use the assistant for outbound qualification. Details on the industries are on the respective industry pages.

Notice Disclosure notice (Art. 50 EU AI Act)

Under Art. 50 of the EU AI Act, from 2 August 2026 people must be informed that they are interacting with an AI system, unless that is obvious. This has to be planned into the deployment from the start, for example as a notice at the beginning of the chat or call.

FAQ

Frequently asked questions

01 Is an AI phone assistant the same as a chatbot?
No. A chatbot works in text on a website, an AI phone assistant runs conversations on the phone. Speech demands more of pace and understanding because there is no thinking time. The assistant responds in real time and sounds natural instead of read out.
02 Does an AI phone assistant need a specific phone system?
No, it connects with common phone systems and numbers. We set up the integration with your existing setup so calls can be routed to the assistant. The exact integration is clarified in the discovery call based on your infrastructure.
03 Does the assistant understand dialects and technical terms?
Modern voice AI understands different ways of speaking well, including light dialects. Technical terms from your industry we add to the knowledge base so the assistant classifies them correctly. When unsure, it asks or hands off instead of guessing.
04 Is the use GDPR-aware?
Yes. Processing runs on servers in Germany or the EU and follows the GDPR. Callers are informed about the AI. Retention and deletion of call data are set before the start, so use stays practically prepared and transparent.
