in Non-Proxy mode and local breakout case is the vSZ involved in Wispr Call FLow?

[anas_fedoul]

Dear commscope community,

I'd like to know if the controller (vSZ-, ZD or other) is involved any part of the Call flow with External Wispr portal and AAA platform like Linkyfi for example or it is the access point who is doing all the job (redirection, radius request, authorization, ..etc)

Thanks
