How does the AI answering machine work?

No call is missed.

The AI answering machine works by having artificial intelligence automatically answer, analyze, and respond intelligently to calls when they are forwarded to the AI's number. The AI answering machine takes calls when no one is available and greets callers with a natural-sounding voice.

Forward messages according to your rules. Transcript included.

With the AI voicemail service, companies or self-employed individuals can set specific times during which calls are forwarded from the business number to the AI number (e.g., during lunch breaks, on weekends, or after work). During the conversation between the AI-powered answering service and the caller, a transcript is generated and sent to the company's specified email address or phone number after the call.

Set it up once. Provide lasting relief.

Our AI-powered answering machine is capable of answering up to 98% of callers' questions and resolving their issues. To answer these questions, you enter all the necessary information about the company, its hours of operation, and its services into the AI’s prompt when setting up the AI. For automated calls, the AI answering machine then draws on this information from the prompts that have been entered.

Seamlessly integrated into your systems.

With our AI-powered answering machine, it is possible to retrieve real-time information from the Internet during a call, synchronize calendars, and access connected databases (such as an order database) directly via API interfaces. Thanks to our extensive integrations, the AI assistant can be seamlessly integrated into existing processes.

No need to listen to the answering machine

With our AI answering machine, employees no longer need to listen to voicemails, as the AI transcribes the entire conversation and sends it via email. Sending the transcript and a summary of the call via email saves the employee in question a lot of time.

Always available

The AI answering machine is always available and takes calls 24/7, which is especially helpful at night, on weekends, or on holidays. It is important for the company to be available at all times so that it does not miss any inquiries.

Saves time and money

Our AI answering machine saves time and money by reducing the workload on employees, minimizing the time spent on routine calls, and having the AI handle information requests. Accordingly, the AI answering machine increases efficiency within the company. Our AI answering machine costs just 0.15 € per minute, making it cheaper than an employee's salary.

Consistent Quality

The AI answering machine ensures consistent quality, as the AI—which is always available—enables better customer service. The company's customers and callers receive assistance at all times, and their questions and concerns are addressed promptly.

More than 35 languages and dialects

Our AI-powered voicemail system is available in more than 35 languages and dialects to reach a variety of target audiences. The digital answering machine can also switch between these languages during a call. The AI voice is available in German, English, Polish, and Spanish, among other languages, as well as in the dialects of Standard German, Austrian German, and Swiss German.

Handles 15 calls at the same time

Fonio's AI-powered voicemail system can handle 15 calls at the same time, which is particularly beneficial for large companies that receive a high volume of calls. 15 concurrent calls also means that customers don't have to wait, don't hear a simple automated message, and don't end up on hold, which increases customer satisfaction.

Versatile

Our AI answering machine is versatile and suitable for all types of businesses and companies (e.g., medical practices, large corporations, self-employed individuals, customer support, tradespeople, and salespeople). Using an AI answering machine takes some of the pressure off the entire team.

Easy integration with existing CRMs

The AI answering machine can be easily integrated into existing CRMs and other business software. The AI answering machine syncs seamlessly with all calendar systems, databases, and CRMs to enable more advanced automations, such as scheduling appointments or checking order status.

No technical knowledge required

No technical knowledge is required to set up our AI answering service, as it can be created easily and quickly in just a few minutes using the prompt (select a language and greeting, fill in the prompts with information about the company, and purchase a phone number).

Easy to understand

Our AI answering machine is easy to understand, doesn't sound robotic, and ensures professional communication with callers. A clear, friendly, and easy-to-understand voice increases customer satisfaction and strengthens their trust in the company, as customers feel well taken care of.

Answers to the Most Important Questions

Our AI answering machine answers the caller's most important questions directly based on the information stored in the prompt. In addition, the virtual voicemail system can access company websites and PDF files directly over the phone.

GDPR-compliant

Our AI answering machine is fully GDPR-compliant, as our main server is located in Nuremberg (Germany) and we host OpenAI on servers in Europe. We store only the most essential information and will delete any requested data upon request.

Who is an AI answering machine suitable for?

Our AI answering machine is suitable for businesses of all sizes and industries that want to improve their communication with customers, patients, or clients and make it more efficient. AI answering machines are ideal for medical practices, tradespeople, law firms, car dealerships, call centers, tax advisors, and hotels, for example.

AI Answering Machine for Tradespeople

An AI answering machine is ideal for tradespeople, as it allows them to assist callers even when they are at customer appointments, on construction sites, or performing installation work. The AI answering machine automatically accepts jobs and schedules appointments for the tradesperson when the AI assistant is linked to the calendar. For tradespeople, an AI-powered voicemail system can also calculate the travel distance to the customer when a job request is received.

AI Answering Machine for a Doctor's Office

An AI answering machine is a good fit for a doctor's office to answer patients' questions, schedule upcoming appointments, and send appointment confirmations via text message or email. To schedule and confirm appointments, the AI answering machine has access to the medical practice's calendar. The AI assistant is able to select an available appointment for the patient and enter it directly into the calendar. An answering machine for medical practices increases patient satisfaction because callers are assisted even outside of office hours.

AI Answering Machines for Businesses

AI answering machines are ideal for businesses to handle incoming calls when no employees are available—for example, on weekends, at night, on holidays, while on vacation, or during meetings. When the team is away, AI-powered voicemail systems can answer calls and handle them automatically by answering common questions and forwarding important inquiries to the appropriate team member. Fonio's AI-powered voicemail system performs automated email and SMS follow-ups and, when necessary, queries internal CRM systems or websites via API.
