## AudioCodes Endpoint

As of April 2025, the AudioCodes Endpoint is deprecated. The full removal of the AudioCodes Endpoint is planned for Q2 2026. Migrate to the [Voice Gateway Endpoint](https://docs.cognigy.com/ai/agents/deploy/endpoint-reference/voice-gateway) before the removal date.

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](https://docs.cognigy.com/ai/agents/develop/node-reference/voice/audiocodes/overview) or [Voice Generic](https://docs.cognigy.com/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.

## Specific Endpoint Settings

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>When async mode is off, outputs are sent only after the entire Flow has finished processing the input.<br>The [Inject and Notify](https://docs.cognigy.com/ai/agents/deploy/endpoints/inject-and-notify) feature only works when async mode is enabled. |
