> 📍 **Where to find it:** Inboxes → Add a channel → Voice

The Voice channel is what lets your agents make phone calls from Madyis Hub. To create it, you connect a Twilio number and your Twilio access keys.

## How it works

The Voice channel relies on a Twilio channel. When you turn it on, Madyis Hub automatically configures the "webhooks" on Twilio (the addresses Twilio calls when a call comes in or changes state) and creates the softphone application needed. The API Key is used only to build the secure token for the browser softphone, while the Account SID and Auth Token are used for server-side operations.

## Step by step

1. Sign in to your Twilio dashboard and note your Account SID and your Auth Token.
2. In Twilio, create an "API Key": you will get an API Key SID and an API Key Secret (the secret is shown only once, so copy it right away).
3. Buy or retrieve a voice-capable Twilio phone number, in international format (e.g. +33XXXXXXXXX).
4. In Madyis Hub: "Inboxes" → "Add a channel" → "Voice".
5. Fill in the number, the Account SID, the Auth Token, the API Key SID and the API Key Secret, then confirm.
6. Add agents to this inbox.

## Good to know

- The number must be in international format with the country code (e.g. +33…), otherwise creation fails.
- If saving fails, it's almost always a Twilio key that was copied wrong: double-check the API Key Secret (shown only once).
- A number using a Twilio "Messaging Service" is not voice-capable: use a real number that can be dedicated.
- The "Voice" option only appears in the channel list if your Pro plan is active.
