# Make a phone call

Places an outbound call from a Twilio number to a phone number, SIP address or client and runs the TwiML you give it when the call connects.

Note: `--from` must be a Twilio number or a verified caller ID. Every completed call is charged, including one a voicemail answers.

## Set up

Use the first option your agent supports.

### CLI (official)

Install the command, then confirm it runs.

```sh
brew tap twilio/brew && brew install twilio
twilio --version
```

Run `twilio api:core:calls:create`.

Set `$TWILIO_API_KEY` in your environment first (get a key: https://www.twilio.com/docs/iam/api-keys/keys-in-console).

Note: Also set `TWILIO_ACCOUNT_SID` and `TWILIO_API_SECRET`, with `TWILIO_API_KEY` holding the API key SID, or sign in once with `twilio login`.

Before anything else, confirm access with the cheapest read-only call, like a list or a search. Never send or change anything to test access.

## Rules

- Ask the user before anything that sends messages, costs money, or changes data, and say how many records it touches. One approval covers a batch the user has seen.
- Never print API keys.
