### Answer
 

To make calls to international numbers using your US Twilio telephony with Retell AI, you need to enable Voice Geographic Permissions in Twilio.
[(1) ](<https://docs.retellai.com/deploy/twilio>)

**Steps:**

1. In your Twilio console, search "geo" to find the **"Voice Geographic Permissions"** setting.


2. Choose **"Elastic SIP Trunking"** in the selector.

3. Select the countries you would like to dial.


This will enable your Twilio elastic SIP trunk to place outbound calls to those international destinations through Retell AI.
