Still, get on the national Do Not Call List. It only takes about a minute to enter your phone number(s) and email id. They will then sent you a confirmation email with a click to confirm link and it's all done for 5 years.
Their are a few groups exempt, politicians for example, but overall it works great, we get maybe a call a month.
Telephone marketers are required to update their list every 30 days. It matters not if it's a recording or a live person, after 30 days they can be fined for every call.
I thought I was on it. Registered again.
