Radiotelephones with blacklist support
prices on 32 modelsBlack list
— the black list allows you to block incoming calls from certain numbers saved in the phone's memory. In this case, the owner of the device will not receive any notification of calls, and the caller will receive a busy signal, call rejection or no answer at all (depending on the model). This feature is useful primarily to protect against unscrupulous calls. A peculiar variation of it is the "white list", when the phone, on the contrary, does not receive calls from any numbers other than those stored in memory.
