With up to 23 minutes of recording time, the VTech 3 Handset CS5329-3 Expandable Cordless Phone with Answering System and Caller ID grabs calls when you can't. The system also features a full- duplex handset speakerphone, which allows both ends to speak and be heard at the same time for conversations that are more true to life. Caller ID entries display on a large, backlit LCD screen so you can see who's on the line even in the dark. Plus, the lighted display indicates how many new messages you have waiting. Easily block up to 150 names and numbers with the Call Block. Add accessory handsets—up to 5 total—with just one phone jack.
