Jobs, phone calls and privacy

I typically don't answer my phone if I don't recognize the number, and 99% of the time it's nothing important. On my Android phone I get phone calls everyday labeled as "Spam Risk". I'm actually expecting calls from potential employers now and don't want to miss any. Are these Spam labels accurate, and I should I continue to ignore them, or could I possibly miss a job recruiter call?
