Lately I'm getting increased spam calls to my Google Voice numbers.
I resorted to setting up an IVR in my PBX.
It was slightly painful getting IVR to successfully answer calls, but now it does.
In a nutshell, I'm forwarding all calls to two free CallCentric DID's from two Google Voice numbers (yes I already checked, Google Voice won't let me use same CC DID to forward both numbers), which then forwards to virtual extension on PBX, which in turn makes IVR pick up the call.
Forwarding calls from Google Voice directly to IVR was met with no ringing on PBX, but ringing on remote end and GV voicemail eventually picking up the call.
So far it seems to work well.
I followed instructions in this thread: https://community.freepbx.org/t/google-voice-to-did-to-extension-ok-but-if-the-call-ends-on-ivr-google-voice-voicemail/10963/5
