My wonderful phone system intercepts these calls. If you have a home phone you should look into the feature full VOIP phone at ITP4Voip.com
I use the whitelist and only calls from those I know even ring. Everyone else goes to voicemail. Most of these scam/slam/spam callers don't even bother to leave a message. It is great! I don't work for the company or have any interest in it.
caller ID had picked up while I was out. The caller said my first name in a questioning tone but left no message.I am so sick of these calls people pretending to know me. But I have their number alright and when home I never answer calls that are identified. The do not call registry is a total waste to sign up with I see no relief from these scammers as they simply ignore it.
