I have the following setup with Anveo: if you're on a whitelist, my phone rings directly, else if you're on a blacklist, you go directly to voicemail. For everyone else, you're asked to press a digit to ring my line, otherwise in a few seconds you go to voicemail. This stops virtually every robocall.
I was forced to implement this after I started getting several junk calls a day. I don't think I've has a single junk call ring through since I put it in place. Rarely one will leave a prerecorded message. Interestingly, from looking at my call logs the frequency of junk call attempts has also dropped to just a couple a week after about a year with this is place.
Another nice thing about Anveo: their voicemail transcription mostly works compared to the comedy that is Google Voice's transcription.
My parents were in the same situation and now I'm doing the same in the UK with an Obi box (Anveo is just a virtual number right?), except without the voicemail. The message asking to press a number just repeats, after a while robocaller gets the idea and hangs up. It got rid of 95% of spammers.
