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:

User says	Action
"Call Rahul at +919876543210"	Outbound call with default assistant
"Use the PolicyBazaar agent to call this lead"	Outbound call with specific assistant
"Launch the feedback campaign"	Campaign launch
"How did the last 10 calls go?"	Call history
"Get the transcript for call XYZ"	Call transcript
"What agents do I have in Ringg?"	List assistants
"Show me today's call analytics"	Analytics

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)
