DESC: The VTech VT2431 is a 2.4 GHz cordless phone system that can support multiple handsets and offers a unique dual speakerphone, one in the base and one in the handset. The base may support up to four cell phone-sized handsets, although the extra three are not included. The speakerphone may be accessed through both the base and the handsets and calls may be placed or received from either location. Spread spectrum technology (SST) is employed in this phone, making it nearly impossible for eavesdroppers to catch your phone conversations. The VT2431 offers a four-line LCD screen on the handset to display Caller ID info and access system and phone menu functions. For those who subscribe to call waiting, this screen will also display who is beeping in during a conversation. For voicemail subscribers, a message indicator will let you know if you have anything new in your mailbox.
