How to put the phone in the black list

Now virtually any mobile phone there is a function "blacklist". Convenient is that it frees the host from unwanted phone calls from known numbers. And those people who call, the answer usually hear short beeps indicating that the room is supposedly busy.

Instruction

1. In order to create your own "black list", go to the main menu of the phone
2. Select menu "settings". Select menu "call" (on some models is the intermediate menu "call log" or "journal").
3. Select "black list". From phonebook, or manually enter one or more of unwanted numbers
4. Save the changes.
5. Different mobile phone manufacturers, this algorithm may differ, but the principle is exactly the same.
   Now, all of whose numbers you put in your own "black list" instead of the usual beeps or ringtones will hear short beeps, and even receive notifications about the absence of the subscriber in the network.
