Hi Retell team,

I’m building an AI receptionist and need native Twilio inbound calling enabled.  
In my workspace, under Deploy → Phone Numbers, I only see SIP trunking and no option  
to connect a Twilio number or get an inbound webhook.

Could you please enable native Twilio telephony / inbound voice webhooks for my account?

Thanks!

Retell AI integrates with Twilio via **Elastic SIP Trunking** , which is the recommended method[(1)](https://docs.retellai.com/deploy/custom-telephony). This approach connects your Twilio numbers to Retell AI’s VoIP infrastructure through SIP, enabling both inbound and outbound calls[(1)](https://docs.retellai.com/deploy/custom-telephony)[(2)](https://www.retellai.com/blog/integrating-ai-with-sip-trunking-and-modern-telephony).

To connect your Twilio number:

1. **Create an Elastic SIP Trunk in Twilio** [(3)](https://docs.retellai.com/deploy/twilio)

2. **Move your Twilio number to the SIP trunk** [(3)](https://docs.retellai.com/deploy/twilio)

3. **Import the number into Retell AI** [(3)](https://docs.retellai.com/deploy/twilio)

Once imported, your number will appear in your Retell dashboard and function like any Retell-purchased number[(3)](https://docs.retellai.com/deploy/twilio). You can assign agents to handle inbound calls and make outbound calls directly[(3)](https://docs.retellai.com/deploy/twilio).

The SIP trunking method you’re seeing in your workspace is the correct integration path for Twilio[(1)](https://docs.retellai.com/deploy/custom-telephony)[(3)](https://docs.retellai.com/deploy/twilio).
