> 📍 **Where to find it:** Conversations → (the contact's profile) → "Call" button; or Contacts → (a contact) → "Call" button

From the profile of a contact who has a phone number, a "Call" button lets you start the call in one click, right from the browser.

## How it works

When you click "Call", Madyis Hub calls the contact's number via Twilio and connects your microphone to the call. A floating call card opens and you follow the status live ("connecting…", "ringing", then the call timer). The call automatically creates or reopens a conversation with that contact.

## Step by step

1. Open a conversation or the profile of a contact who has a phone number.
2. Click the "Call" button (phone icon).
3. If you have several Voice numbers, choose the one to use in the window that appears.
4. Allow the microphone if the browser asks, then speak.
5. Click the red button to hang up.

## Good to know

- The button only appears if the contact has a phone number AND at least one Voice inbox is configured.
- The outgoing call is tied to you: it doesn't appear for the other agents.
- Mind consent and cold-calling rules (e.g. Bloctel in France) before calling a prospect.
- Check that your microphone works: if you hear nothing, see the article about choosing the speaker.
