I effectively did this with Google Voice back when.

I would give marketers my Google voice number, it had better interface (and on cloud instead on device) contact management. I could send non favorites to a voice identification prompt (voiding all slow recordings or agents making multi calls that have a pickup delay) and for the final small percentage voice transcripts that I could determine if important.

Or for craigslist, I could forward calls to a phone for a short period of time, then turn off forwarding.

I still use google voice like that, give it out when I absolutely have to give a phone number (because they verify by text or whatever) but have the app set to silent.

Google does a really good job of filtering out the telemarketing calls so the rare message is usually valid.

Pretty much the only time I have to open the app is this one stupid company (coughWalmartcough) which insists on doing 2FA via text every single time I want to check the balance on my prepaid debit card.
