AI phone assistant for automated call handling
An AI phone assistant answers incoming calls automatically, understands spoken requests in natural language, handles common questions and books appointments directly in your calendar. It works around the clock and routes complex inquiries to your staff. OptiAI sets up the assistant for companies in Vienna and across the DACH region and integrates it with your existing systems.
What an AI phone assistant does
The AI phone assistant takes over the tasks that tie up the most time on the phone: call handling, information, scheduling and routing. It understands natural language instead of rigid menu navigation and conducts a genuine conversation with the caller.
Automated call handling
The assistant answers every incoming call immediately — even outside business hours and when lines are busy. No caller gets a busy signal or ends up in a hold queue.
Natural language understanding
The AI understands spoken requests in natural language, not just fixed menu options. Callers can phrase their concern freely — the assistant captures the content and responds appropriately.
Direct appointment booking
The assistant checks available slots in your calendar, books directly and confirms the appointment with the caller. Scheduling conflicts and double bookings are avoided.
Inquiry handling and routing
The assistant resolves common questions — opening hours, status updates, product information — on its own. It routes complex inquiries to the right staff member with a note attached.
AI call handling does not rely on a fixed script sequence. Callers can phrase their concern freely — the assistant captures the content and responds appropriately. This makes the flow more natural for the caller than a voice menu and lowers the barrier to stating the concern. If you want to combine the assistant with other automated workflows, see our page on process automation for recurring business workflows for further approaches.
Who benefits from an AI phone assistant
An AI phone assistant pays off when a significant share of incoming calls consists of recurring standard inquiries and availability outside business hours is a concern. Specifically, this applies to:
High call volume outside business hours
If you receive most calls after 6 p.m., on weekends or during peak times and currently lose them, the assistant closes these gaps.
Recurring standard inquiries
When a large share of calls consists of appointment requests, information or status updates, the assistant takes over these tasks. Your staff stays free for more demanding topics.
Typical industries include medical practices and healthcare facilities that schedule appointments by phone, trades businesses with high call volumes in field service, and B2B service providers that need to receive and qualify inquiries. Companies with fewer than 20 employees and very low call volume generally do not benefit enough. Whether an implementation makes sense in your case is something we clarify in a short conversation.
How the implementation works
Implementing an AI phone assistant follows four phases. A standard implementation takes four to six weeks.
Needs analysis
We capture your call volume, the most common inquiries and the systems the assistant should connect to. The initial consultation is free and non-binding.
Configuration and training
We set up call handling, store your answers and train the AI on your inquiries. The voice output is tailored to your company’s tone.
Integration and testing
The assistant is connected to your calendars and systems. Before go-live we test with real calls and make any necessary adjustments.
Go-live and ongoing optimization
After go-live we monitor call logs, evaluate common inquiries and refine the responses. You receive a monthly report on calls and appointments.
What an AI phone assistant costs
The cost of an AI phone assistant is made up of two components: a one-time setup fee for configuration, training and integration, and an ongoing operating flat rate for hosting, maintenance and optimization.
The setup fee depends on the number of inquiry types the assistant should handle and the effort involved in system integration. The ongoing flat rate is based on call volume and the number of connected lines. We provide concrete prices in an individual quote once we have captured your volume and requirements.
If you combine the assistant with other services — such as the process automation and AI integration from our service portfolio — synergy effects on costs may arise. The initial consultation for the needs analysis is free and non-binding.
Difference from traditional answering machines and call centers
The AI phone assistant differs from both a traditional answering machine and a call center. Understanding the difference helps you decide which solution fits your requirements.
Difference from a traditional answering machine
An answering machine records calls and plays a fixed announcement. The caller cannot leave a concern that is understood and processed. The AI phone assistant conducts a conversation: it captures the request in natural language, answers questions, books appointments and routes complex cases. The caller does not need to call back.
Difference from a call center
A call center employs agents to answer calls. That means staffing and infrastructure costs, shift planning and variable availability. The AI phone assistant is available around the clock without interruption and scales with call volume — no additional shifts required. It handles standard inquiries; complex advisory conversations stay with your staff.
Frequently asked questions
Answers to the most common questions about the AI phone assistant, implementation and costs.
An AI phone assistant answers incoming calls automatically, understands spoken requests in natural language, handles common questions and books appointments. It works around the clock and routes complex inquiries to your staff. Unlike a traditional answering machine, it conducts a genuine conversation with the caller.
The AI phone assistant is ideal for companies with high call volumes consisting mainly of recurring requests — such as appointment bookings, opening-hours inquiries or status updates. It is particularly useful for medical practices, trades businesses and service providers with 20 to 500 employees that lose calls outside business hours.
A standard implementation takes four to six weeks. During this time we configure call handling, train the AI on your inquiries and connect the assistant to your calendars and systems. Before go-live we test with real calls and make any necessary adjustments.
Costs consist of a one-time setup fee and an ongoing operating flat rate. The amount depends on call volume, the number of inquiry types and the integration effort. In a short conversation we assess your volume and prepare an individual quote — the initial consultation is free.
Yes. We connect the assistant to your calendars, CRM systems and customer databases. Integration with standard systems such as Microsoft 365, Google Workspace or common CRM solutions is straightforward. For custom systems we review the options in a technical assessment.
