Your Do Not Call List (or DNC Lists) can be found under Files and Do Not Call Lists. To add a number to the list, Click the Manage icon, which looks like a wrench and screwdriver.
1. To add a phone number, type in the 10 digit phone number in the “Add Phone:” field and select go. (Name is optional.)
2. If someone wishes to be removed from your Do No call List (i.e. they want to be called by your office), you will input the 10 digit phone number in the Remove Field.
