* Twilio credentials (API keys, account information)

<Warning>
  **Voice Capability Required**: Make sure your phone number supports voice

  outgoing voice calls.
</Warning>

### Step 1: Access Telephony Settings

1. **Navigate to Voice Widget**: Go to your chatbot dashboard and select the "Voice Widget" tab
2. **Select Telephony Tab**: Click on the "Telephony" tab to access phone number management

### Step 2: Add Your Phone Number

1. **Click 'Add Phone Number'**: Select the "Add Phone Number" button to open the configuration modal
2. **Enter Phone Number Details**: Fill in your Twilio phone number and provide a descriptive label

### Step 3: Provider-Specific Configuration

#### Twilio Setup

For Twilio integration, you'll need:

* **Account SID**: Your Twilio Account SID (starts with "AC")
* **Auth Token**: Your Twilio Auth Token (keep this secure)

2. Navigate to Account > Account dashboard
3. Copy your Account SID and Auth Token
4. Ensure your phone number has voice capabilities enabled

### Step 4: Configure Inbound Calling

After adding your phone number:

1. **Setup Inbound**: Click the "Setup Inbound" button next to your phone number
2. **Automatic Configuration**: OKChat will automatically configure the necessary webhooks and routing
3. **Verify Status**: Confirm the status shows "Inbound Ready" with a green indicator

### Step 5: Configure Outbound Calling (Optional)

For outbound calling capabilities:

#### Twilio Outbound Setup

1. **Setup Outbound**: Click the "Setup Outbound" button next to your Twilio phone number

3. **Automatic Configuration**: OKChat will configure the SIP trunk and authentication

<Warning>
  **Whitelist Destination Countries in Twilio**: For outbound calls to work, you
  must whitelist destination countries in your Twilio account. In your Twilio
  Console, search for **Programmable Voice**, then navigate to **Voice
  Geographic Permissions**. Select the countries you need from the **Low Risk**
  tab and save your changes.
</Warning>
