# AudioCodes

<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>

AudioCodes Nodes help you build a voice AI Agent using [AudioCodes configuration](/ai/agents/deploy/endpoint-reference/audiocodes).

### [Call Recording](/ai/agents/develop/node-reference/voice/audiocodes/call-recording)

This Node controls the voice recording capabilities of the conversation.

### [Hang Up](/ai/agents/develop/node-reference/voice/audiocodes/hangup)

This Node instructs AudioCodes to end the call.

### [Play URL](/ai/agents/develop/node-reference/voice/audiocodes/play-url)

This Node lets you retrieve a WAV file from a URL location and play it back to the user.

### [Send Message](/ai/agents/develop/node-reference/voice/audiocodes/send-message)

This Node sends a text (optionally with SSML) to AudioCodes, which then turns this text into speech (TTS) and outputs it to the caller.

### [Send Metadata](/ai/agents/develop/node-reference/voice/audiocodes/send-meta-data)

This Node sends metadata via SIP INFO messages to the connected SIP trunk.

### [Set Session Parameters](/ai/agents/develop/node-reference/voice/audiocodes/set-session-params)

This Node configures the AudioCodes Session. All parameters set within this Node are valid for the remainder of the session unless overwritten, either directly or by activity parameters.

### [Transfer](/ai/agents/develop/node-reference/voice/audiocodes/transfer-vg)

This Node enables the forwarding of an active call to a Tel or SIP target.
