# AI Voice Agent for Inbound Calls

An AI voice agent that answers calls, books appointments and qualifies enquiries, connected to your phone system and hosted in the EU.

## The challenge

Calls arrive exactly when nobody has time for them. The person in charge is in a meeting, the number goes to voicemail, and a share of those callers dial a competitor next. Many of these conversations follow the same script: an appointment, a status question, a transfer. That is the part that ties up staff who would do more elsewhere.

## Our solution

We build a voice [agent](/en/glossary/agent) for one clearly bounded call path, attach it to the phone system you already run and connect it to your calendar, [CRM](/en/glossary/crm) or ticket system. The agent picks up, states at the start that it is an automated system, handles the defined case and hands over to a person as soon as the conversation leaves that scope. Operation and call data sit on our own infrastructure in the EU. Every call ends with a result your team can read back in your system.

## Use cases

- **Call handling outside opening hours**: The agent picks up in the evening and at weekends, clarifies the request, records callback details and creates a CRM entry. In the morning there is a sorted list instead of a voicemail box.
- **Appointment booking over the phone**: The agent checks free slots in the calendar, books the appointment, sends the confirmation and attaches open questions as a note. The calendar API prevents double bookings.
- **Qualifying inbound enquiries**: The agent asks a fixed set of questions about need, timing and responsibility. Matching enquiries go straight to sales, the rest lands in a queue with a note.
- **Status answers in support**: Recurring questions about order, delivery or processing status get answered from the connected system. When the case deviates, the agent hands over to a person.
