### Answer
To enable outbound calls to other countries using Vapi, you typically need to set up a phone number that can place international calls. This can be done through Vapi directly or by integrating with external providers like Twilio or Vonage, which support international dialing capabilities.
1. **Using Vapi Directly**: You can purchase or manage phone numbers directly through Vapi that are capable of making outbound calls internationally. You would need to ensure that the phone numbers you acquire through Vapi are enabled for international calling [(1)](
) .
2. **Using Twilio or Vonage**: If you prefer to use a custom solution like Twilio, you can import phone numbers into Vapi from Twilio or Vonage that are set up for international calling. This requires configuring the phone number in Twilio or Vonage to allow international calls and then importing it into Vapi using the appropriate API endpoints or dashboard settings [(1)](

For calling the UAE specifically, you must ensure that the number you are using (either through Vapi directly or via Twilio/Vonage) supports calls to the UAE. This often involves additional setup in the external provider's platform to enable and fund international calling.
If you are facing issues specifically with calling the UAE, it might be related to restrictions or configurations in your Twilio or Vonage account that need to be adjusted to allow calls to this region. Check with your provider about any specific settings or restrictions for international calling to the UAE.
