A group of users can be created with a purpose of receiving voice announcements through the speaker of a telephone set, but it has to be in the waiting mode.
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.
