Panasonic KX TG6413

Engineered to work in 1.9GHz frequency, Panasonic's DECT 6.0 phones won't conflict with common wireless devices such as 2.4GHz routers, wireless keyboards and mouses, microwave ovens and other household items. And because it's digital, you'll enjoy long range and clear sound while deterring eavesdropping.Store the caller ID info of any and all unwanted callers into your phone's call block list so that you can eliminate future pesky calls from them. After their information is stored, they'll get a busy signal if they call you again.Now you can program each handset to ring or not at your discretion. For example, before you go to sleep, set the bedside handset to silent mode so that it won't ring for the duration of your slumber. In the meantime, the handset in another room is unaffected, and rings as usual.
