+
+# `openclaw voicecall`
+
+Plugin-provided voice call functionality (requires voice-call plugin).
+
+## Overview
+
+The `voicecall` command is a plugin-provided feature available when the voice-call plugin is installed and enabled.
+
+## Key Commands
+
+```bash
+# Check call status
+openclaw voicecall status --call-id <id>
+
+# Initiate a call
+openclaw voicecall call --to "+15555550123" --message "Hello" --mode notify
+
+# Continue a call
+openclaw voicecall continue --call-id <id> --message "Any questions?"
+
+# End a call
+openclaw voicecall end --call-id <id>
+```
+
+## Webhook Exposure
+
+Expose webhooks using Tailscale:
+
+```bash
+# Serve mode
+openclaw voicecall expose --mode serve
+
+# Funnel mode
+openclaw voicecall expose --mode funnel
+
+# Disable exposure
+openclaw voicecall unexpose
+```
+
+## Security Guidance
+
+Only expose the webhook endpoint to networks you trust. Prefer Tailscale Serve over Funnel when feasible due to security considerations.
