Why Callwise

What sets us apart.

Our difference

We build the agent with you — no self-serve configurator.

Intro call, joint setup, fine-tuning in your tone of voice. You don't need to understand AI to run it.

Custom workflows

If-then logic, data lookups against your systems, smooth handoff to a human when things get complex.

Multilingual

Multiple agents in parallel, automatic routing — callers land in their own language.

EU / GDPR

Data processing in the EU, GDPR-compliant. Twilio in the backend for stable telephony.

FAQ

Honest answers to the obvious questions.

SetupHow does the phone number work?

We provide a dedicated number for the agent. You can use it as your main line, in parallel to your existing one, or forward your existing number to the agent — e.g. only after hours or when busy. We'll figure out what fits in the intro call.

OperationsWhat happens if the AI doesn't understand something?

It either forwards to you with full context, or takes a callback request with all the details. It never guesses or hangs up.

OperationsCan it handle multiple languages?

Yes. We host one agent per language and route callers to the right one automatically — at no extra cost compared to a single-language setup.

ContractCan I cancel anytime?

Yes. Monthly billing, monthly cancellation. No long contracts, no setup lock-in.

TechDoesn't it sound robotic?

Modern voice models sound natural — most callers don't notice. Best way to judge: call the number above and hear for yourself.
