Pstn line monitoring - obihai obi312 - polycom

I’m currently looking at monitoring incoming calls on my pstn line.
I was considering leveraging OBi312 (ex obihai - now polycom) as it has a FXO port (connect to pstn line) and using the obihai integration (

My question is : is model obi312 supported with the obihai integration, taking into account the fact that it is now a polycom device ?

Thank you for any feedback.
