The workaround I used for this was Google Voice. I put the Google Voice number on my resume and in settings told it to use my own GV number as the caller id. If I saw a call coming from the GV number I knew it was a response to my resume. For some reason my GV number doesn’t attract scammers.

Pro tip for you: you can "port" out your number to your cellular provider.

Zero spam for me for a long time. Yes, zero!

Also see the T Mobile spam service. There's two you have to turn on IIRC.

YouMail for voicemail is good too.

Thank you!

I have a GV number as my work number on my cards, site, etc. and I still get spam through it, though admittedly less than through my personal number.

That is a great tip, thanks!
