The subscriber device (1) includes a call identification circuit (5) and a memory (10) storing telephone numbers. A comparator (15) compares the call number with the stored telephone numbers, to allow data corresponding to the call number provided by the memory to be fed to a display (20). When the call information is not identified by the comparator the call number is shortened and the corresponding exchange is identified for indication via the display. |
