How It Works

Making a Call

When you say "call +1-555-123-4567 about the project":

1. Clawly initiates the call via your provider
2. AI voice handles the conversation
3. You can continue or end the call
4. Get a transcript when done

Receiving Calls

If you set up inbound handling:

1. Configure your inbound policy (allowlist recommended)
2. Add allowed phone numbers
3. Set a custom greeting
4. AI handles incoming calls automatically

Voice Customization

Voice calls use your configured TTS provider:

• OpenAI - Natural voices (alloy, echo, fable, onyx, nova, shimmer)
• ElevenLabs - Premium multilingual voices

Configure in your OpenClaw settings under messages.tts.

Tips

• Confirm before calling - Always verify the phone number
• State purpose clearly - Have a clear objective for each call
• Respect timezone - Don't call too early or late
• Use appropriate mode - Notify for announcements, Conversation for discussions
• Test with mock provider - Use mock provider for development
