My Callcentric service has been a blessing in that regard.
They use True CNAMS to determine if the call is from a known source of SPAM callers. And I can customize how I want them to handle it if it is.
When I initially got the service, I optioned it to give it the 'three tones' disconnect and a recording saying that the number is no longer in service. Even if they call back, my phone will never ring.
If it happens to be from a number that is not on that list, I can add the number to my blacklist so that Callcentric treats it the same way or a different way, if I want.
I had to spend a fair amount of time setting up the call treatments so my calls would be handled the way I wanted them to. This can be based one the number called, the calling number, the day and time, and other options.
I can make it ring my office phone during the day. I get a 'Press 1 to accept this call' message when a call made to my home number rings into my office phone. So I know to answer it like a residential call after I press 1 to accept it. I do the same with my cell phone.
I have a Grandstream four port VOIP box (four analog extensions on one VOIP device) so I can receive calls through their service at home.
They have voice mail and texting services as well. And many other features. If you get just their basic services, it will cost about sixteen dollars per month.
They are very cost effective. Look them over at
Stopping SPAM calls is only the tip of the iceberg with them.
