A fully functioning telephone is included, along with a digital answeringsystem capable of storing up to 18 minutes of messages in three mailboxes. The auto-redial function is quite handy, while a 50-entry speed dial and automatic fax-phone switching also add to the efficiency of the KX-FP155. A variable printing resolution allows you to extend precious toner life, while a 50-sheet paper tray and an out-of-paper reception of up to 28 pages help to cut down on those too-frequent paper restocking runs. Panasonic backs the KX-FP155 with a one-year limited warranty.
