Hi Lynn. While Presto was designed to be used with an analog phone line, we know that many customers are successfully using it with digital lines. Normally, the phone line would attach to the Printing Mailbox and the converter, with another phone cable going from the converter to the wall jack. If you let us know the model of converter you've purchased, our customer support staff is happy to help you figure out the set up.
