I was inundated with calls almost 24/7, the TPS is used by rogues as it gives them a nice list of known live numbers.
@ 3 years ago I bought a trueCall unit , I now never get any calls that I don't want, it is awesome.
Blocker, call recorder, can list all in/out calls for evidence and bill checking ,plus answer phone all in one unit.
Black/white list numbers, intercepts and answers calls for you,numerous ways to deal with calls, you can even give blacklisted calls the number unobtainable tone, that trick gets your number off the live targets list very quickly ))
Have to say, it is the best purchase I made in years.
