# Twilio

# Using Twilio for calling

Twilio is the most popular telephony engine for Movoice AI units. It provides robust global connectivity and simple number management.

## Integration Steps

### 1. Get Your Credentials

Log in to your [Twilio Console](https://console.twilio.com). Your **Account SID** and **Auth Token** are displayed on the home dashboard.

### 2. Purchase a Number

In Twilio, navigate to **Phone Numbers > Manage > Buy a Number**.

* **Important**: Ensure the number has **Voice** capabilities.
* For outbound calls, localized numbers (matching your target audience's area code) often see higher pick-up rates.

### 3. Webhook Configuration (For Inbound)

If you want to receive calls on your Twilio number:

1. Copy the Movoice **Inbound Webhook URL** from your dashboard.
2. In Twilio, go to the settings for your phone number.
3. Under **Voice & Fax**, set **A CALL COMES IN** to "Webhook" and paste your Movoice URL.

### 4. Testing Your Setup

Use the **Make Call** feature in the Movoice dashboard to trigger a test call to your personal phone using your newly connected Twilio number.

## Troubleshooting

* **Permission Denied**: Check if your Twilio account is in "Trial" mode. You may need to upgrade to make calls to non-verified numbers.
* **Geo-Permissions**: Ensure you have enabled the geographic region (e.g., India, UK) you are attempting to call in your Twilio Voice Settings.
