### Answer Yes, you can use your own business phone number (including an Indian number) with Retell AI by importing it via custom telephony/SIP trunking. For Retell-purchased numbers: The Create Phone Number API currently only supports US and CA country codes. [(1) ]() For your own numbers (like an Indian number) : You can import your existing phone number using the Import Phone Number API. [(2) ]() This requires:

javascript
import Retell from 'retell-sdk';
const client = new Retell({
  apiKey: 'YOUR_RETELL_API_KEY',
}) ;
const phoneNumberResponse = await client.phoneNumber.import({
  phone_number: '+14157774444',
  termination_uri: 'someuri.pstn.twilio.com',
}) ;

Key requirements for importing your number: -

phone_number

(required) : Your number in E.164 format -

termination_uri

(required) : The termination URI from your elastic SIP trunk provider (e.g., Twilio, Telnyx) - You can optionally bind

inbound_agent_id

and

outbound_agent_id

to handle calls Note on international calling: For imported numbers, international calling capabilities depend on your telephony provider's settings. [(3) ]() Check out these resources for more details: - [Import Phone Number]() - [Custom Telephony guide]()
