# Receive Incoming Calls

> Route inbound calls to an agent

Register a number bound to an agent so inbound calls are answered automatically.

```bash theme={null}
curl -X POST https://api.agentic-os.com/api/v1/voice-numbers \
  -H "Authorization: Bearer $AGENTIC_OS_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "provider": "PLIVO",
    "number": "912269976288",
    "connectionId": "YOUR_PLIVO_INTEGRATION_ID",
    "agentId": "AGENT_ID"
  }'
```

`connectionId` is your connected telephony integration's ID — list integrations
via `GET /integrations` (platform-core) to find it.

Once registered, any call to that number is answered by the agent — no additional
setup is required. Call logs and transcripts appear the same way as outbound calls.
