Does the call blocker keep the phone from ringing at all, when it receives unwanted calls?

Does the call blocker keep the phone from ringing at all, when it receives unwanted calls?

Yes the Call Blocker has First Ring Suppression built-in which prevents phones connected to the TEL port from ringing on the first ring. All other phones connected directly to the phone company will ring once. Your options to avoid the first ring is to connect your phones to the Call Blocker and turn off the phones connected directly to the phone company. You can also use a cordless phone system to distribute the ringing around the house instead. This will avoid the first ring completely. Caller ID is also repeated to all phones connected to the Call Blocker.
