The government is as fed up as you are with nuisance Robocalls and e-mail spam. While SPAM is a tougher nut to crack, Robocalls are quite easy, once have the telecom providers on board that is - either voluntarily, or by the threat of fines. Recently, the FCC began to encourage the carriers to deal with this.
CNN recently came out with a very good article explaining how the wireless carriers are dealing with this . They also make some good suggestions. One of which is the advice we always give our clients. If the number is blocked, or not familiar, let it go to voice mail. as thats what it is for. I get over a dozen hangups a day from people calling my number but not leaving any type of message. Like with e-mail, answering or following up is a bad idea because it just validates your number or e-mail as legit so they can sell it. Unfortunately, that government Do Not Call list does not stop most of these folks.
If you have a cloud based voIP phone system, it's very easy to set it up to make the caller chose an extension. I have my auto attendant set up to ask the caller which department they want. If it's a legit caller, they press the button and leave a message. I have the attendant repeat the messages with available extensions twice. If after two times, they have not pressed a button, they are disconnected. Robodialers cannot enter extensions and therefore are hung up on.
