• 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 before the removal date.

AudioCodes Nodes help you build a voice AI Agent using AudioCodes configuration.

Call Recording

This Node controls the voice recording capabilities of the conversation.

Hang Up

This Node instructs AudioCodes to end the call.

Play URL

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

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

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

Set Session Parameters

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.
