No missed
call.
Never again.
Our voice agents sound like real people — with a German voice built on ElevenLabs and AI logic from Retell AI. They answer calls, understand what's needed, book appointments in the calendar, and transfer when necessary.
// Natural voice
// Calendar sync
// CRM integration
// 24/7 available
Where a voice agent makes immediate sense.
Trades business
The boss is on site, the office empty. The voice agent takes the call, notes the name, address and problem, and books a proposed appointment.
Doctor's / dental practice
No more hold queues. Book, cancel or reschedule an appointment — the voice agent checks the calendar live and confirms.
Service providers & consulting
Lead qualification right on the phone. Only qualified enquiries are put through to your team — everything else is transcribed.

Where voice agents make the difference.
Medical practices
Appointment booking, prescription renewals, sick notes — without the practice assistant being permanently on the phone. 90% of appointments run automatically.
Trades emergency service
At night, on weekends, on holidays — the agent picks up, qualifies the emergency, prioritises urgency and transfers for genuine emergencies.
Restaurants & Hotels
Reservations, room enquiries, opening hours, allergies. Takes more calls than a team ever could.
Law firms
Initial-consultation qualification: type of matter, urgency, opposing party, timeframe. The agent documents, the lawyer calls back prepared.
Customer support
Order status, returns, basic technical questions. 70% of calls are resolved without human involvement.
Outbound / callbacks
Following up on open quotes, confirming appointments, follow-up after a visit. Polite, persistent, never annoyed.
What's under the hood.
Retell AI & ElevenLabs
For the telephony infrastructure we build on Retell AI — currently the platform with the lowest latencies for German-language calls. Voices come via ElevenLabs (multilingual-v2 model), optionally your own cloned voices.
As an alternative we offer Vapi — depending on the use case.
- Model: Claude (dialogue understanding) + GPT-4 (fallback)
- Speech recognition: Deepgram nova-3 · multilingual
- TTS (speech output): ElevenLabs · more than 30 German voices
- Latency: < 700 ms end-to-end (perceptibly "natural")
- Phone number: your own DE number (landline or mobile)
- Call recording: optional, GDPR-compliant with consent
- Integrations: same as for chatbots (calendar, CRM, email, Slack)
From brief to live operation.
Briefing
Which calls should it handle? What's your business's tone? What's the escalation path? We listen in on real calls for a week.
// Week 1
Conversation design
Dialogue flows, prompts, escalation triggers. We design the agent's "character" — not robotic, not too chatty.
// Week 2-3
Test run
You and colleagues call in, test, give feedback. We refine wording, pace and escalations. At least 200 test calls.
// Week 4-5
Going live
Set up call forwarding. Monitoring of the first 100 real calls. Fine-tuning. After week 6 it runs on its own.
// Week 6
Frequently asked.
As of 2026: untrained ears don't notice. For transparency we still recommend having the agent say at the start: "I'm Lisa, the digital assistant for [company]". That builds trust and meets current DSK recommendations on labelling AI.
We build in clear escalation paths: on phrases like "I want to speak to a real person", an aggressive tone, a medical emergency or after 2 misunderstandings, the call is transferred immediately to a stored mobile number — or, if busy, a callback with a full transcript is promised.
Standard German with a light dialect accent: yes (Bavarian, Austrian, Swiss German at acceptable quality). Strong dialect (deep Bavarian, Swabian, Viennese): limited. We test extensively in your customers' region before going live.
Health data falls under Art. 9 GDPR. We configure the agent so that it stores no diagnoses, medication names or conditions in plain text. It can hear and process "I need an appointment for back pain", but the field in the booking is then simply labelled "reason", not the original quote.
The Profi tier (€3,499 + €349/mo) includes 800 minutes/month. Beyond that a minute costs €0.15 net. For most trades businesses and practices the Profi tier is entirely sufficient.
After each call a summary lands in your Slack, email and CRM: who called, what they wanted, what was agreed, what data was exchanged. The full transcript can optionally be viewed — archived for 30 days, then deleted (GDPR compliance).
Voice agent + website or chatbot?
Voice agents catch calls — chatbots catch online enquiries. Both combined with your website make a real 24/7 lead engine. Up to 17% bundle discount.
