Example code:
javascript
const registerCallResponse = await retell.call.createPhoneCall({
from_number: '+14157774444', // replace with the number you purchased
to_number: '+12137774445', // replace with the number you want to call
}) ;
console.log(registerCallResponse) ;
Before making calls, you must bind an outbound agent to your phone number.
To monitor calls via webhooks, you can set up webhooks to receive notifications for:
- **Call Started**: When the call connects
- **Call Ended**: Final status and duration
- **Call Analyzed**: Transcript and analysis ready
You can also test outbound calls directly from the dashboard by clicking "Make an outbound call" and entering the phone number with country code. [(2) ]()
