### Answer For outbound calls, yes, you can make calls from your GHL number through Retell AI using the

from_number

parameter [(1) ]() . When making outbound calls, you specify which number the call should originate from . The

from_number

parameter accepts your Retell-managed or imported number in E.164 format (e.g.,

+14157774444

) . This means if you've imported your GHL number into Retell AI, you can use it as the caller ID for outbound calls [(1) ]() [(2) ]() . To set this up: 1. Import your GHL number into Retell AI using the Import Phone Number API, providing the termination URI to identify your elastic SIP trunk [(2) ]() [(3) ]() 2. Bind an outbound agent to that number so it knows which AI agent to use for calls from that number [(4) ]() [(5) ]() 3. Make outbound calls using that number as the

from_number

[(1) ]() Here's an example of making an outbound call with a specific number:

javascript
const registerCallResponse = await retell.call.createPhoneCall({
 from_number: '+14157774444', // your GHL number
 to_number: '+12137774445', // destination number
 override_agent_id: 'agent_abc123',
}) ;

So the call will appear to come from your GHL number to the recipient, while Retell AI handles the AI agent conversation .

### Answer You can import a phone number into Retell AI using the Import Phone Number API [(1) ]() . This is done programmatically through an API call rather than through the dashboard UI . Here's how to import a number using the API :

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

When importing, you'll need to provide : - **phone_number**: Your number in E.164 format (e.g.,

+14157774444

) - **termination_uri**: The termination URI to identify your elastic SIP trunk (for Twilio, it ends with

.pstn.twilio.com

) You can also optionally include authentication credentials (

sip_trunk_auth_username

and

sip_trunk_auth_password

) , bind inbound/outbound agents, and add a nickname for reference . Once imported, the number will show up in your dashboard and can be used for making and receiving calls [(2) ]() .
