# Connect Twilio

#### **Region-Specific Restrictions (UK, Germany, France, etc.)**

Due to telecom regulations, certain countries require **business verification** and **address documentation** before purchasing or using numbers.

If you’re trying to purchase a number in one of these countries, you’ll need to:

1. Create a **Twilio account** directly on twilio.com.
2. Complete Twilio’s **Number Registration Process** for your country.
   * Twilio will guide you through submitting required documentation (e.g., business license, ID, proof of address).
3. Once your number is verified and active in Twilio, you can **connect it to your Stammer account** using your **Twilio SID** and **Auth Token**.

#### **Connecting an Existing Twilio Account**

If you already have an active Twilio number or prefer to manage numbers manually, you can connect your account directly to Stammer.

Here’s how:

1. In the **Phone Numbers** page, click **Integrate Twilio** in the top-right corner.
2. Enter your **Twilio Account SID** and **Auth Token**.
3. Once connected, your Twilio numbers will automatically sync and appear in your Stammer dashboard.
4. You can then assign any of those numbers to your voice agents.

#### **Managing Active Numbers**

After you’ve purchased or connected numbers, they’ll appear in your **Active Numbers** list.\
From there, you can:

* Assign each number to a specific **Voice Agent**
* View number details and location
* Release or replace numbers
* Monitor usage and billing
