This is one of the issues that can plague any sales professional using leads that may have not been scrubbed against a national, and state level DNC list.
There are a lot of autodialers on the market and alot of people selling leads, and I can tell you this that if you're not compliant with the technology that automatically cleans the lists before your "standard autodialer" starts sending out those calls....you could get a slap on the hand or worse.
Technology, and systems are advancing now that if anyone does enough due diligence, they can save themselves alot of hassle, and at the same time put plenty of qualified leads in their hands. One such system out there that is gaining national attention is Gold Calling,

Much more than an "autodialer", on of the important features is that any list used, even if you purchase a list "Cleaned against DNC" is automatically scrubbed against the National, and State level DNC lists.
Also important, that the leads being used are people that have actually requested information about the products and services you offer.
By using systems and vendors that are compliant in the regards to the TCPA is of the utmost importance, and I would caution anyone who is considering buying a $5000 autodialer system and a bunch of leads with the premise that you're going to stike gold at the other end of the line.
