The BT 8600 Quad Advanced Call Blocker Digital Cordless Phone with Answering Machine is a sleek and efficient home phone system. With four handsets, this trimline phone in black offers convenience and ease of use. Its advanced call blocking features provide added security and control over your phone calls. The digital cordless phone from BT is a reliable and stylish addition to any household. This has been fully tested. One of the handsets does not come woth batteries, and another doesn't hold its charge very well so I would recommend replacing the AAA batteries. They have been tested with the batteries from the other two that are fully functioning and hold there charge.
