Answered call because it was a local number. Woman asked for the "man or lady of the house". I told her we are on the do not call list. She persisted and again asked for the man of the house. Gave the phone to my cat.
Called the number back. Got a prerecorded message that no one was able to answer the call. And if I wasn't interested in the fund raising effort I could press"1" to have my number removed. So it is some unknown fund raising effort.
It is not a violation of the DNC Registry unless they attempt to sell you goods or services over the phone. And should they, the DNC will not take any action unless your caller is a Registered with the FTC Telemarketing company.
