Ringg Voice Agent Skill for OpenClaw

This skill connects OpenClaw to Ringg AI — a Voice OS for enterprises that provides low-latency (<337ms), multilingual (20+ languages) AI voice agents for phone interactions including lead qualification, feedback collection, confirmations, and more.

Prerequisites

• A Ringg AI account with API access
• RINGG_API_KEY environment variable set (obtain from Ringg AI dashboard)
• RINGG_WORKSPACE_ID environment variable set
• Optional: RINGG_DEFAULT_ASSISTANT_ID for a default voice agent
• Optional: RINGG_DEFAULT_FROM_NUMBER for outbound calls

Configuration

Add to openclaw.json under skills.entries:

{
  "skills": {
    "entries": {
      "ringg-voice-agent": {
        "enabled": true,
        "apiKey": "RINGG_API_KEY",
        "env": {
          "RINGG_API_KEY": "<your-ringg-api-key>",
          "RINGG_WORKSPACE_ID": "<your-workspace-id>",
          "RINGG_DEFAULT_ASSISTANT_ID": "<optional-default-assistant-id>",
          "RINGG_DEFAULT_FROM_NUMBER": "<optional-default-number>"
        }
      }
    }
  }
}

Available Actions

1. Make an Outbound Call

Initiate a call from a Ringg AI assistant to a phone number.

# Basic outbound call
curl -X POST "https://api.ringg.ai/v1/calls/outbound" \
  -H "Authorization: Bearer $RINGG_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "assistant_id": "<assistant-id>",
    "to_number": "+919876543210",
    "from_number": "+918001234567",
    "dynamic_variables": {
      "customer_name": "Rahul",
      "order_id": "ORD-12345"
    }
  }'

Parameters:

• assistant_id — ID of the Ringg voice agent to use (falls back to RINGG_DEFAULT_ASSISTANT_ID)
• to_number — Destination phone number in E.164 format
• from_number — Caller ID number (falls back to RINGG_DEFAULT_FROM_NUMBER)
• dynamic_variables — Key-value pairs passed into the agent's conversation context

When the user says "call +91XXXXXXXXXX" or "make a call to [name/number]", use this action. If no assistant_id is specified, use RINGG_DEFAULT_ASSISTANT_ID. If no from_number is specified, use RINGG_DEFAULT_FROM_NUMBER.

2. Launch a Campaign

Trigger a batch calling campaign for multiple contacts.

curl -X POST "https://api.ringg.ai/v1/campaigns/launch" \
  -H "Authorization: Bearer $RINGG_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "campaign_id": "<campaign-id>",
    "contacts": [
      {"phone": "+919876543210", "name": "Rahul", "custom_field": "value"},
      {"phone": "+919876543211", "name": "Priya", "custom_field": "value"}
    ]
  }'

When the user asks to "launch a campaign", "start calling a list", or "run outbound calls for [list/segment]", use this action.

3. Check Call Status

curl -X GET "https://api.ringg.ai/v1/calls/{call_id}/status" \
  -H "Authorization: Bearer $RINGG_API_KEY"

Returns: call status (ringing, in-progress, completed, failed), duration, transcript summary, and disposition.

4. Get Call History & Analytics

# Recent call history
curl -X GET "https://api.ringg.ai/v1/calls/history?limit=20" \
  -H "Authorization: Bearer $RINGG_API_KEY"

# Analytics for a time range
curl -X GET "https://api.ringg.ai/v1/analytics?from=2026-02-01&to=2026-02-06" \
  -H "Authorization: Bearer $RINGG_API_KEY"

When the user asks "how did the calls go", "show me call analytics", or "what happened on yesterday's calls", use these endpoints.

5. List Assistants

curl -X GET "https://api.ringg.ai/v1/assistants" \
  -H "Authorization: Bearer $RINGG_API_KEY"

When the user asks "which agents do I have", "list my ringg assistants", or needs to select an assistant before making a call, use this.

6. Get Call Transcript

curl -X GET "https://api.ringg.ai/v1/calls/{call_id}/transcript" \
  -H "Authorization: Bearer $RINGG_API_KEY"

When the user asks "what was said on the call" or "get the transcript", use this.

Webhook Integration (Inbound Events)

Ringg AI can push real-time call events to OpenClaw via webhooks. To receive call status updates, transcripts, and dispositions:

1. Expose OpenClaw's webhook endpoint:

   ngrok http 18789
   

2. Configure the webhook URL in Ringg AI dashboard or via API:

   curl -X POST "https://api.ringg.ai/v1/webhooks" \
     -H "Authorization: Bearer $RINGG_API_KEY" \
     -H "Content-Type: application/json" \
     -d '{
       "url": "https://your-ngrok-url.ngrok.io/webhook/ringg",
       "events": ["call.completed", "call.failed", "call.transcript_ready"]
     }'
   

3. OpenClaw will receive POST payloads with call events that can trigger agent actions.

Usage Patterns

Natural language triggers → actions:

Error Handling

• 401 Unauthorized: Check RINGG_API_KEY is valid
• 404 Not Found: Verify assistant_id, call_id, or campaign_id exists
• 429 Rate Limited: Back off and retry after the indicated interval
• Phone number format: Always use E.164 format (e.g., +919876543210 for India)
