Description

Pass `--to`, `--from` (a Twilio number or a verified caller ID) and the call's instructions as `--twiml` or as a `--url` that returns TwiML. Every completed call is charged, including one a voicemail answers. The REST call is `POST https://api.twilio.com/2010-04-01/Accounts/{AccountSid}/Calls.json`. The CLI also needs `TWILIO_ACCOUNT_SID` and `TWILIO_API_SECRET`, or a `twilio login` profile.
