Outbound Call

> Source code and setup guide: github.com/humanjesse/hostinger-openclaw-guides

Place outbound phone calls using the ElevenLabs voice agent with Twilio. The voice agent on the call uses OpenClaw as its brain — same as inbound calls.

When to use

When the user asks you to:

• Call someone or phone someone
• Make a phone call
• Dial a number
• Ring someone
• Place a call to a number

How to use

Run the call script with a phone number in E.164 format:

python3 skills/outbound-call/call.py +1XXXXXXXXXX

With an optional custom first message (what the agent says when the recipient picks up):

python3 skills/outbound-call/call.py +1XXXXXXXXXX "Hi John, I'm calling about your appointment tomorrow."

With optional call context (passed as a dynamic variable to the agent):

python3 skills/outbound-call/call.py +1XXXXXXXXXX "Hi, this is a quick follow-up call." "Customer requested callback about billing issue #4521"

Phone number format

• US numbers: +1 followed by 10 digits, e.g., +15551234567
• If the user gives a number like 555-123-4567 or (555) 123-4567, reformat it to +15551234567
• Always confirm the formatted number with the user before placing the call

Rules

• ALWAYS confirm the phone number with the user before placing a call
• NEVER place a call without explicit user consent
• Report the result back to the user (conversation ID on success, error details on failure)
• If the call fails, explain the error and suggest fixes
