# Phone Caller

Make automated calls for urgent alerts.

## Quick Start

### Make a Call

```bash
# Using Twilio API
curl -X POST https://api.twilio.com/2010-04-01/Accounts/$TWILIO_SID/Calls.json   --data-urlencode "To=+1234567890"   --data-urlencode "From=$TWILIO_PHONE"   --data-urlencode "Twiml=<Response><Say>Alert: Server CPU is at 95 percent</Say></Response>"   -u "$TWILIO_SID:$TWILIO_TOKEN"
```

### Send SMS

```bash
# Send text message
curl -X POST https://api.twilio.com/2010-04-01/Accounts/$TWILIO_SID/Messages.json   --data-urlencode "To=+1234567890"   --data-urlencode "From=$TWILIO_PHONE"   --data-urlencode "Body=Your appointment is tomorrow at 2 PM"   -u "$TWILIO_SID:$TWILIO_TOKEN"
```

## Setup

```bash
# Set environment variables
export TWILIO_SID="ACxxxxx"
