Based on the available search results, I cannot provide a definitive answer to your specific question about the AudioConnector WebSocket and IVR port allocation.
The search results offer high-level overviews of Genesys Cloud architecture and troubleshooting but do not detail the precise lifecycle of IVR ports or channels during a WebSocket streaming session. They cover other areas, such as general troubleshooting for SIP and RTP issues, IVR design using Data Tables, and high-level architectural layers, but none address the specific resource allocation scenario you described.
To find the exact answer, please consult the official Genesys Cloud developer documentation, particularly the sections on Architect flows, AudioConnector WebSocket API, and Media Services.
