voice-call

What This Skill Does

The voice-call skill allows OpenClaw agents to manage interactive voice communications directly through the platform. By integrating with major telecommunication providers like Twilio, Telnyx, or Plivo, the skill transforms the agent from a text-based interface into an active phone assistant. It enables automated outbound calling, real-time message delivery during active calls, status monitoring, and graceful call termination. Whether you are building an automated notification system, an interactive customer service bot, or a simple outbound alerting mechanism, this skill provides the necessary control layer to interact with voice infrastructure without writing custom middleware.

Installation

To integrate this skill into your environment, use the OpenClaw command-line interface. Run the following command in your terminal:

clawhub install openclaw/skills/skills/blockcloud/voiceskill123

After installation, you must configure the plugin in your plugins.entries.voice-call.config file. Depending on your chosen provider (Twilio, Telnyx, or Plivo), you will need to supply your specific credentials such as API keys, account SIDs, and the verified fromNumber. For local testing or development purposes, you can set the provider to "mock" to simulate voice interactions without consuming real credit or needing network connectivity.

Use Cases

This skill is ideal for businesses looking to automate their outreach. Common use cases include:

• Appointment Reminders: Automatically dial clients to confirm scheduled appointments and offer rescheduling options.
• Emergency Alerting: Instantly contact stakeholders with critical updates via a voice message when system thresholds are triggered.
• Voice-Activated Surveys: Call a list of recipients to collect feedback or responses to specific questions.
• Identity Verification: Deliver one-time passcodes or verification status messages via automated phone calls.

Example Prompts

1. "Please initiate a voice call to +15555550123 and inform them that their scheduled server maintenance will begin in ten minutes."
2. "What is the current status of the active call with ID call-9982, and can you check if the recipient has hung up yet?"
3. "Speak to the current caller and let them know that we have received their ticket and a support representative will join them shortly."

Tips & Limitations

• Provider Costs: Always monitor your balance with your chosen telephony provider, as calling carries real-world costs.
• Latency: Because this relies on external API calls, there may be slight latency between issuing a command and the audio being delivered.
• Compliance: Ensure all calls comply with local telecommunications regulations, such as TCPA or GDPR, specifically regarding consent and opt-out mechanisms.
• Mock Mode: Utilize the mock provider during initial testing to ensure your workflow logic is sound before deploying with paid API keys.
