Directed Call Pick Up
The function allows the user by entering a 5-digit number to receive a call from any concrete company’s telephone. There are no definite groups for picking up the call. One can pick up the call from any telephone set; it is only necessary to enter the required code and the extension number of the phone, which has to be picked up.
Some telephones, depending on the brand and model, have the intercom function, which allows to begin communication by sending the signal. When the signal comes, the telephone set rings a signal different from the standard ring tone call. After that the telephone temporarily switches off from the telephone line and works as an intercom.
