Has anyone got Home Assistant to work with an IP phone as a local voice control?

I have a Grandstream GXP 2140, and I cannot get it talking to HA for the functionality. It doesn’t have the same settings as the Grandstream pots to IP Phone device from the article.

I have Whisper and Piper installed, and showing up under the Wyoming protocol. I have the IP Phone addon installed, but it never detects my phone.
