The handsets have large backlit keys and backlit LCD displays, and the base has a handset locator button. The phone has a couple of features, including a caller block list that gives a busy signal to undesired callers. The handsets have independent silent modes (one can ring while others are silent), and the inclusion of the second and third handsets also means that the handset-to-handset intercom is enabled. There is still room for expansion with up to 3 more handsets, for a total of 6. Other features include caller ID, call waiting ID, ringer ID and 3-way conference calling. This package has the most handsets of any KX-TG6411T package that Panasonic offers, so additional handsets (if desired) must be purchased separately.
