About the service
We build voice agents that take inbound calls, qualify the caller, book appointments in your calendar and write everything into the CRM. The agent speaks natural German with regional accent tolerance, hands over to a human when the case demands it, and works alongside your existing phone system rather than replacing it.

Challenges we solve
- #1
Calls outside office hours go to voicemail and most callers never leave a message.
The agent answers around the clock, captures name, concern and preferred appointment, and either books directly or creates a callback task with priority for the next morning.
- #2
The team fears customers will be annoyed by talking to a machine.
The agent introduces itself transparently as a digital assistant and offers a human transfer at any moment. In practice acceptance is high because the alternative was nobody picking up at all.
- #3
Callers speak dialect or switch to English mid-sentence.
We use speech models tuned for German variants including Austrian and Swiss usage, with automatic language switching and a confidence threshold that triggers a human handover when recognition drops.
- #4
Recording calls raises legal questions in Germany.
We implement an explicit consent announcement at call start, store audio in the EU with a defined retention period, and can operate transcript-only mode where recordings are not wanted at all.
AI voice agents (AI telephony)
In most service businesses, one in four calls goes unanswered and a large share of those callers dial the next provider instead of calling back. A voice agent closes that gap without adding headcount: it picks up on the first ring, handles the routine questions and passes qualified enquiries to your team with a written summary. You define the script, the escalation rules and the boundaries; we build, test with real recordings and tune it weekly for the first month.
