According to the FTC Do not Call list Registry web site:

Some calls are exempt from the National Do Not Call Registry.

The do not call provisions do not cover calls from political organizations, charities, telephone surveyors, or those companies with which a consumer has an existing business relationship. This means you are allowed to contact your own customers even if they are on the DNC list. And you can send anyone an audio voicemail message to their cell phone. It is classified as an electronic message just like an email because the recipient's phone never rings. It is considered an electronic message sent server to server.

We will append valid phone numbers to any mailing list or update new phone numbers on older lists. Our software flags any record that appears on any State, or the Federal Do Not Call list.
