## Description

<Warning>
  * As of Cognigy.AI 4.96.0, AudioCodes Nodes and Generic Voice Nodes are deprecated. Flows with these Nodes continue to work, and you can still edit and clone them as well as export them as a Package. However, you can't create new ones in Cognigy.AI 4.96 or later.
  * The full removal of AudioCodes Nodes is planned for Q2 2026. After the removal, AI Agents using these Nodes will stop working properly. We strongly recommend migrating to [Voice Gateway Nodes](/ai/agents/develop/node-reference/voice/voice-gateway/overview) before the removal date.
</Warning>

The Send Metadata Node sends metadata via SIP INFO messages to the connected SIP trunk.

| Parameter | Type | Description                        |
| --------- | ---- | ---------------------------------- |
| Metadata  | JSON | The metadata to send via SIP INFO. |

Example:

```json theme={null}
{
  "myParamName": "myParamValue"
}
```

<Note>
  This Node supports Activity Parameters. You can find more information about activity parameters on the [Parameter Details](/ai/agents/develop/node-reference/voice/voice-gateway/parameter-details) page.
