- 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](https://docs.cognigy.com/ai/agents/develop/node-reference/voice/voice-gateway/overview) before the removal date.

The Generic Voice Nodes are a set of Nodes for creating voice Flows that are not specific to one Endpoint. These Voice Nodes are compatible with both voice integrations: AudioCodes and Voice Gateway.

### [Barge In - Config](https://docs.cognigy.com/ai/agents/develop/node-reference/voice/generic/barge-in-config)

This Node is a session config that enables the interruption of the voice AI Agent. When executed, the settings will apply for the remainder of the session.

### [Continuous ASR - Config](https://docs.cognigy.com/ai/agents/develop/node-reference/voice/generic/continuous-asr-config)

Continuous ASR enables the system to concatenate multiple STT recognitions of the user and then send them as a single textual message to the voice AI Agent.

### [DTMF Collect - Config](https://docs.cognigy.com/ai/agents/develop/node-reference/voice/generic/dtmf-collect-config)

Enables capturing of DTMF signals by the voice AI Agent during the entire call session. When executed, the settings will apply for the remainder of the session.

### [Hang Up](https://docs.cognigy.com/ai/agents/develop/node-reference/voice/generic/hang-up)

This Node instructs the system to end the call.

### [Mute Speech Input](https://docs.cognigy.com/ai/agents/develop/node-reference/voice/generic/mute-speech-input)

This Node controls when speech user inputs can be collected in your Flow.

### [Play URL](https://docs.cognigy.com/ai/agents/develop/node-reference/voice/generic/play-url)

The Play URL Node lets you stream a sound file into the call with the ability to loop it. MP3 and WAV encoded files are supported.

### [Send Metadata](https://docs.cognigy.com/ai/agents/develop/node-reference/voice/generic/send-metadata)

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

### [Session Speech Parameters - Config](https://docs.cognigy.com/ai/agents/develop/node-reference/voice/generic/session-speech-parameters-config)

This Node enables the change of speech parameters during the Flow.

### [Transfer](https://docs.cognigy.com/ai/agents/develop/node-reference/voice/generic/transfer)

This Node lets you pass an active call to a tel or sip target.

### [User Input Timeout - Config](https://docs.cognigy.com/ai/agents/develop/node-reference/voice/generic/user-input-timeout-config)

This Node defines the action that the AI Agent should take if it does not receive any input from the user within a certain timeframe.
