Block phone number

[professor]

How can I completely block a specific phone number so it will not get through to my home phone and ring?

We're being harassed by some third party collection organization looking for someone who we've never heard of.

For Verizon residential service, you can try Call Intercept. Or, is this is a number that does not show on caller ID, you can try Anonymous Call Rejection.
