Prerequisites

1. Twilio Account

1. Visit https://www.twilio.com and sign up
2. During setup, choose:
   • "With code" (for full API access)
   • "Voice" channel
3. Bind a credit card (required for production use)

2. Purchase a Phone Number

1. Go to Phone Numbers → Buy a Number
2. Select United States (easiest, no address verification needed)
3. Filter by Voice capability
4. Purchase a local number (~$1/month)

3. Get Your Credentials

From the Twilio Console homepage, copy:

• Account SID (starts with AC...)
• Auth Token (click to reveal)

4. Verify Your Phone Number (Trial Accounts)

Trial accounts can only call verified numbers:

1. Go to Phone Numbers → Verified Caller IDs
2. Add your phone number
3. Complete verification via SMS or voice call

Note: Upgrade your account ($20 minimum) to call any number without verification.

Setup

Run the setup script to configure your Twilio credentials:

bash

bash ~/.openclaw/workspace/telcall-twilio/scripts/setup.sh

You will be prompted to enter:

• Account SID
• Auth Token
• Twilio phone number (e.g., [phone])
• Your phone number (e.g., [phone])

Usage

Basic Call

bash

bash ~/.openclaw/workspace/telcall-twilio/scripts/call.sh "Your message here"

With OpenClaw

Simply tell your assistant:

• "Call me: Server is down!"
• "Emergency call: Security breach detected"

The assistant will use this skill to make the call.

Troubleshooting

"Number is unverified"

Call doesn't go through

1. Check your Twilio number has Voice capability
2. Verify your Auth Token is correct
