<Warning>
  As of April 2025, the AudioCodes Endpoint is deprecated. The full removal of the AudioCodes Endpoint is planned for Q3 2026. Migrate to the [Voice Gateway Endpoint](/ai/agents/deploy/endpoint-reference/voice-gateway) before the removal date.
</Warning>

The AudioCodes Endpoint enables you to connect your AI Agent to your contact center or other phone numbers using the [AudioCodes](https://www.audiocodes.com/) platform. This Endpoint allows your customers to speak with your AI Agents instead of using a chat.

## Prerequisites

* A Flow configured with [AudioCodes](/ai/agents/develop/node-reference/voice/audiocodes/overview) or [Voice Generic](/ai/agents/develop/node-reference/voice/generic/overview) Nodes.
* To link the AudioCodes Endpoint to a phone number, contact your Cognigy representative to provision and configure a Voice Gateway instance.
* The Cognigy AudioCodes Endpoint is 100% compatible with [AudioCodes VoiceAI Connect](https://voiceaiconnect.audiocodes.com), where you can sign up for free and get a phone number within minutes.

## Generic Endpoint Settings

Learn about the generic Endpoint settings on the following pages:

* [Endpoints Overview](/ai/agents/deploy/endpoints/overview)
* [NLU Connectors](/ai/platform-features/nlu/external/nlu-connectors/overview)
* [Data Protection & Analytics](/ai/agents/deploy/endpoints/data-protection-and-analytics)
* [Real-Time Translation Settings](/ai/agents/deploy/endpoints/real-time-translation-settings)
* [Transformer Functions](/ai/for-developers/transformers/overview)

## Specific Endpoint Settings

<Accordion title="Voice Gateway Settings">
  | **Parameter** | **Description** |
  | - | - |
  | Async Mode | When async mode is enabled for the AudioCodes Endpoint, outputs are sent directly as they are processed in a Flow. This mode is useful when the Flow needs to send an HTTP request. <br /><br />When async mode is off, outputs are sent only after the entire Flow has finished processing the input.<br /><br />The [Inject and Notify](/ai/agents/deploy/endpoints/inject-and-notify) feature only works when async mode is enabled. |
</Accordion>
