- 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.
