| `POST` | `/public/agent/{uuid}` | [Trigger an outbound call by API Trigger node](/api-reference/calls/trigger) |

| `POST` | `/telephony/inbound/{workflow_id}` | [Inbound call webhook](/api-reference/calls/inbound) |
## Choose the right public call route
Dograh exposes two public outbound call route families. They are **not**
interchangeable, even though both path parameters look like UUIDs.
| Use this when | Production route | Test route | Identifier you pass |
|---|---|---|---|
| You added an **[API Trigger node](/voice-agent/api-trigger)** to the workflow and want to call that trigger | `/public/agent/{uuid}` | `/public/agent/test/{uuid}` | The trigger UUID (`trigger_path`) from the API Trigger node |
| You want to execute the workflow by its stable **Agent UUID** instead of a trigger node | `/public/agent/workflow/{workflow_uuid}` | `/public/agent/test/workflow/{workflow_uuid}` | The workflow UUID from the agent's **[Agent UUID](/configurations/agent-uuid)** field |
<Note>
Do not pass a workflow UUID to `/public/agent/{uuid}` and do not pass a trigger UUID
to `/public/agent/workflow/{workflow_uuid}`. Dograh treats these as different
identifier types and the request will fail if you mix them up.
</Note>
Once Dograh resolves the target agent, both route families behave the same:
- They accept the same request body
- They return the same response shape
- They validate the same `X-API-Key` organization boundary
- They use the same telephony configuration selection rules
If you specifically need the API Trigger route, see [Trigger an outbound call by API Trigger node](/api-reference/calls/trigger). To execute by workflow UUID, see [Trigger an outbound call by workflow UUID](/api-reference/calls/trigger-workflow).
## Using initial context
`initial_context` passes runtime data into the agent at call time. Values are available as template variables in your agent's prompt using double-brace syntax.
```json
{
"initial_context": {
"customer_name": "Jane",
"appointment_date": "March 15"
}
}
```
Your agent prompt can then reference `{{customer_name}}` and `{{appointment_date}}` and they will be substituted when the call starts.
## Run status values
| Status | Description |
|---|---|
| `pending` | Call queued but not yet connected |
| `in_progress` | Call is live |
| `completed` | Call ended normally |
| `failed` | Call failed before or during execution |
