Ask in a chat
Tell your assistant what you need. It writes the plan, you say yes, and a few minutes later the answer is in the chat.
“Move my dentist appointment to Friday.”
Invite-only pilot
Give your agent a phone number and a voice.
CallAgent lets any AI agent make real phone calls. You approve the plan, it makes the call, and you get the result back as text.

Workflows
Three ways people put it to work.
Same phone line, same safeguards. What changes is who asks for the call.
Run it from your systems
Connect it once, then let your own workflows start calls in bulk. Results come back as structured data.
“Confirm tomorrow’s slots with all hubs.”
Build it into your product
Give every user of your own agent the ability to call. You integrate once, and your users switch it on.
“Book us a table for four at eight.”
What a call looks like
You ask once. The agent handles the call.
01
Ask
Say what you need in plain words, the way you’d brief a colleague.
02
Check
Your agent shows you who it will call and what it will say. Nothing happens until you agree.
03
Call
A natural voice makes the call, says it’s an AI, and asks you if something unexpected comes up.
04
Result
What was agreed, the key facts, and a transcript you can read.
Agent
Hallo, ich rufe für Alex Berger an, ich bin übrigens eine KI. Es geht um einen Kontrolltermin.
Praxis
Moment, ich schau kurz nach. Donnerstag halb drei, oder Freitag früh.
Agent
Donnerstag 14:30 passt. Also Donnerstag, 14:30 Uhr.

Genau, bis dann!

Case studies · fictional examples
What it looks like in practice.
500calls a day, Fernweg Logistik. One IT person, every hub confirmed before the trucks roll.
1integration for every Schmock user. A WhatsApp agent that can now book the table.
1 hsaved a day at Moosgruber. The agent waits on the hotline so nobody else has to.
Fernweg Logistik, Schmock and Moosgruber Steuerberatung are invented companies. The scenarios show what CallAgent is built for; they are not customer reports. Read all three.
Why CallAgent
Agents can book a flight. Calling the dentist is still on you.
Practices, tradespeople, small shops and public offices often only answer the phone. CallAgent lets your agent handle those calls too.
Real conversations
Natural, quick replies. It copes with interruptions, call screening and voicemail.
You stay in control
Nothing dials before you approve. Every call has a time limit, and you can stop it at any moment.
Honest and private
Every call says it’s an AI. No audio is recorded, and transcripts are deleted after 7 days. Hosted in Frankfurt.

Vision
Call tool, not tool call: where voice agents go next
Today an agent asks a person to make the call. Soon the phone is just another tool, and then a channel agents use to reach each other.
Felix Huber · 8 Oct 2026 DevelopersOne block of config
No SDK, no webhook server, no audio pipeline. What we left out on purpose.
Mira Ostermaier · 1 Oct 2026 ProductWhy your agent still can’t pick up the phone
Agents browse, book and buy. The moment a task needs a phone call, the agent hands it back. The problem isn’t the model.

FAQ
Common questions
What’s included in the free test call?
One real call to the number you register at sign-up. It runs the full flow — plan, approval, a conversation of up to four minutes, the result — and only counts if it connects.
Does the agent say it’s an AI?
Yes, in every call. This can’t be turned off.
Are calls recorded?
No. Audio is never saved. Text transcripts are visible only to you and are deleted after 7 days.
Which languages does it speak?
German and English. More languages are coming.
Do I need to be a developer?
Not really. Connecting is one line of config that you copy from your dashboard. Developers find the full reference in the docs.
Where is my data processed?
On servers in Frankfurt. Twilio carries the phone line and OpenAI provides the voice model. Details are in the Datenschutzerklärung.
When does a test call count as used?
Only when it connects. A busy line, no answer or a failed dial doesn’t count.
Do I need a credit card?
No.
