What is an AI phone assistant?

Software that automatically answers incoming phone calls, handles questions, books appointments and forwards to a human if needed. Unlike traditional answering machines or IVR menus (Press 1 for…), it has real conversations in natural language, answers from the company's stored knowledge and understands industry-specific terminology.

How much does an AI phone assistant cost in Germany?

Some providers bill per minute, with a sales setup. For an SMB with regular call volume, a fixed monthly price is usually easier to plan. Traditional human phone services usually bill per call and are mostly reachable on weekdays.

Is an AI phone assistant GDPR-compliant?

Depends on the provider. rinqo relies on servers in Germany, AI processing with contractually assured EU data processing, no training on customer data and a DPA you sign on registration. With providers that process in the US, the transfer usually relies on the EU-US Data Privacy Framework, which is politically contested, and the providers are subject to the CLOUD Act.

What happens when the AI phone assistant cannot answer a question?

It says so honestly, captures the request in a structured way and either offers a callback by your team or puts the call straight through. The open question appears in the dashboard, you can add to the knowledge base in a minute, and next time the agent can answer the question. That way its knowledge grows with every gap you close.

What's the difference between an AI phone assistant and an answering machine?

An answering machine plays a message and records a voicemail. An AI phone assistant has a real conversation: understands the question, answers based on your knowledge, can ask follow-ups, book appointments, forward when needed.

Does an AI phone assistant work with my practice/workshop/firm system?

rinqo connects directly with calendar tools like Google Calendar, Microsoft Outlook and CalDAV calendars (such as iCloud). Conversation results go to your own systems via webhook. We set up a direct connection to practice management systems, law firm software or industry-specific ERP systems with you, provided they offer an interface.

AI Act Art. 50, what do I need to know from 02 August 2026?

The EU AI Act requires from 02 August 2026 that every caller is clearly informed at the start of the conversation that they are talking to an AI. Fines for violation: up to €15M or 3% of global annual turnover. At rinqo the notice is part of the preset greeting by default ("This is the AI assistant of [practice name]"), wording is editable; the note that it is an AI should stay in.

Can I see beforehand how it would work for my business?

Yes. Leave your details. We clarify with you what your business needs and show you beforehand how the phone agent would work for it. Convinced? Then the setup follows. The monthly plan can be cancelled monthly.

Folded-paper still life on the subject of AI phone assistant

SolutionAI phone assistant

AI phone assistant for your company.

GDPR-compliant. From Germany.

Every missed call is a lost order. But a traditional phone service bills per call and is usually only reachable on weekdays; round-the-clock cover costs extra.

In short

Someone who calls and reaches nobody rarely calls a second time. Busy lines, conversations with other customers at the same moment and calls outside business hours are the most common reasons. Until now, the classic answer came in two options: a human phone service (reliable, but billed per call and usually weekdays only) or voicemail (free, but a conversion killer). Since 2024 there has been a third: an AI phone assistant that answers calls, answers industry-specific questions, books appointments and forwards to your team when needed, 24 hours a day, in your main language, chosen from 17+ languages, and in English. The market is fragmented: many US providers deliver strong technology but no GDPR compliance. Providers from the DACH region close the compliance gap, but differ widely in EU sovereignty, industry depth and pricing model.

rinqo is the AI phone assistant for DACH SMBs, with three non-negotiable essentials: first, GDPR-compliant on servers in Germany, with EU data processing and a DPA under Art. 28 GDPR. Second, the AI notice under Art. 50 AI Act built into the preset greeting by default. Third, industry depth with ready-made industry templates, for example for medical practices, law firms, trades, tax advisors, property management, real estate and hair salons. For health data and professional secrecy, a supplementary agreement or Section 10 of the DPA applies before going live. We guide you through setup.

The DACH market for AI phone assistants, three segments at a glance

The DACH market for AI phone assistants splits into three segments. First, SMB specialists from the DACH region: solutions with EU hosting and SMB pricing, some focused on a single industry such as craft or medical practices. Second, enterprise platforms: conversational AI for contact centers with 100+ agents, built for corporate clients, with matching project and sales effort. Third, US voice AI providers: technically capable, but processing in the US, which depends on the EU-US Data Privacy Framework and is subject to the CLOUD Act. Plus industry verticals covering one single industry only. rinqo positions itself in the first segment: servers in Germany, industry templates plus wizard, multi-channel from one platform. The choice depends on the use case: a corporate contact center needs something different than a practice with three lines.

DACH SMB specialists: EU hosting, SMB pricing, sometimes one industry only. rinqo: multi-channel + industry templates
Enterprise platforms: contact centers from 100 agents, project setup, corporate pricing
US voice AI: technically strong but Cloud Act exposure for DACH data
Industry verticals: deep in one industry, not deployable outside of it

AI phone assistant vs. traditional phone service, which fits your business?

Traditional phone service providers work with human staff handling multiple client accounts in parallel. Advantage: empathy and situational judgment. Disadvantage: billing per call, usually available on weekdays only, round-the-clock cover at extra cost, fixed scripts, no multilingual coverage. An AI phone assistant like rinqo is different in four aspects: first, 24/7 without surcharge because scaling cost approaches zero. Second, the agent learns from your knowledge, your website, FAQ list, documents, and answers industry-deep questions that a generic call-center script cannot anticipate. Third, a main language from 17+ languages, plus English, without extra cost. Fourth, full calendar integration with calendar tools like Google Calendar, Outlook or a calendar with CalDAV access (such as iCloud or Nextcloud).

What does an AI phone assistant cost? 2026 price comparison

DACH pricing for AI phone assistants varies widely. Three models dominate: hybrid plans with included minutes and per-minute overage fees, per-call billing with a minute allowance, and flat rates. With per-minute models, costs rise with every minute of conversation; with per-call models, with every call. On top of that there is usually the phone number. The main cost driver is not the number of calls but industry depth: generic providers are cheap, while industry-specific solutions with GDPR compliance cost more. rinqo relies on a fixed monthly price with industry depth.

Entry level: phone minutes for a small business, one phone number, all industry templates.
More volume and more simultaneous conversations.
A larger allowance and even more simultaneous conversations.
Custom volume, a dedicated contact, SLA.

Automated call handling, how does an AI phone assistant (voicebot) work technically?

A modern AI phone assistant works in four layers. First layer: telephony bridge, incoming call lands via SIP trunking (at rinqo: telephony via a provider based in the EU, with speech processing on servers in Germany) on a dedicated phone number. Second layer: speech-to-text, speech is transcribed in real time, at rinqo with processing in the EU. Third layer: Large Language Model, text is contextualized (knowledge base, industry template, conversation history) and a response is generated. At rinqo this runs with contractually guaranteed EU data processing, with no training on customer data. Fourth layer: text-to-speech, response is converted to audio (a German speech synthesis provider with processing in the EU), played back through the SIP bridge. The agent waits until the caller has finished speaking, then answers. Plus: forwarding based on keywords you define, appointment booking in your calendar, and an automatic email summary to your team after every conversation.

How to recognize a strong AI phone assistant, four hard criteria

Anyone comparing AI phone assistants for DACH use should apply four hard criteria: EU sovereignty (where does the LLM run?), AI Act Art. 50 compliance (implemented before 02.08.2026?), industry depth (how many ready templates?) and setup effort (who does it?). rinqo's answers: AI processing within the EU (contractually assured), AI notice built in by default, industry templates plus wizard, guided setup. Many solutions on the market only meet some of these criteria: strong technology without ready industry templates, deep specialization in one single industry, or sales-led setup with hosting outside Germany. Check all four points before committing, they decide legal certainty and day-to-day usability.

Frequently asked questions

At rinqo we guide you through setup for a standard industry (medical practice, craft, law firm, tax advisor, hairdresser, property management, real estate): click through the wizard, read the knowledge base from your website, assign a phone number, start a test call. Sales-driven providers typically have onboarding processes whose duration varies by use case and provider (details on the providers' own websites).

Yes. For fixed patterns such as shortness of breath, unconsciousness, heavy bleeding, chest pain or a smell of burning, it tells the caller to dial the emergency services (112) themselves and passes the call to your team right away. Further keywords, such as a power cut or water damage, you set as forwarding rules. Example from a medical practice: the practice template also refers callers to the on-call medical service (116117), and the practice is notified.

Both terms describe the same idea: software that talks, listens and answers on the phone. In practice, 'phone assistant' is often used for simpler systems that just play announcements, while 'voice agent' points to the AI-driven kind. An AI voice agent like rinqo has a real conversation, understands the request, answers from your company knowledge and books appointments, letting the caller finish speaking along the way.

A voicebot is a speech AI that handles inbound and outbound phone calls fully automatically, technically the same as an AI phone assistant. “Voicebot” emphasises the technology (speech AI made of telephony bridge, speech-to-text, language model and speech synthesis), “AI phone assistant” emphasises the task (answering calls, answering questions, booking appointments). At rinqo it's the same product: a voicebot with servers in Germany, processing in the EU and an AI notice built in by default. Unlike an IVR menu (“Press 1”), it understands natural language and holds real conversations.
