outbound-call

What This Skill Does

The outbound-call skill enables your OpenClaw agent to act as a voice assistant capable of initiating telephone conversations. By leveraging the seamless integration between ElevenLabs' sophisticated voice synthesis models and Twilio’s telecommunications infrastructure, this skill allows for natural, human-like voice interactions over standard cellular or landline networks. When triggered, the agent utilizes its core reasoning capabilities to guide the conversation, ensuring that the outbound experience is just as intelligent and context-aware as an inbound request. Whether you need to automate appointment reminders, perform follow-up calls, or initiate outreach to clients, this tool provides a programmatic interface to reach human contacts directly.

Installation

To integrate this functionality into your environment, use the OpenClaw management CLI. Open your terminal and execute the following command:

clawhub install openclaw/skills/skills/humanjesse/outbound-call

Ensure you have configured your ElevenLabs and Twilio API credentials within your environment variables as specified in the setup guide.

Use Cases

This skill is designed for scenarios where proactive communication is required. Common use cases include:

• Automated customer support follow-ups regarding open tickets or billing issues.
• Appointment confirmation and rescheduling workflows.
• Outbound sales or lead qualification.
• Proactive alerts for time-sensitive notifications where email might be ignored.

Example Prompts

1. "Please call +15550109988 and tell them that the plumbing repair has been rescheduled for Tuesday at 10 AM."
2. "I need to check in with the client at (555) 987-6543 about the project status; can you handle that for me?"
3. "Call the support desk at 555-444-3333 and mention that I'm still waiting on the document regarding the internal audit."

Tips & Limitations

• Phone Format: Always ensure phone numbers strictly follow E.164 format (+1 followed by 10 digits). The agent is programmed to handle reformatting, but providing clean input reduces errors.
• Verification: Always abide by the safety rule to verify the destination number with the user before execution to prevent accidental calls to incorrect parties.
• API Costs: Be aware that both Twilio and ElevenLabs charge per-minute or per-request fees; monitor your usage within their respective dashboards.
• Context: Providing specific call context in the terminal command significantly improves the agent's ability to maintain a coherent conversation flow upon connection.
