I recently came across a GE Dect 6.0 cordless phone with a "do not disturb"
option - there is a button on the based which toggles the ringer off/on for
all handsets. Unfortunately this particular phone has received consistently
terrible reviews. Does anyone know of a phone system (three or more
handsets) that is rated well and has this feature? Other phones I've seen
can toggle the ringer, but it involves too many steps and is inconvenient
for daily use.
