Abstract: A portable cellular telephone capable of recognizing a Calling Line Identifications (CLI) signal. The telephone comprises a memory for storing telephone numbers and a counter for storing the respective number of calls received from telephone numbers stored in the memory. Preferably the counter comprises for each number stored in the memory an associated portion (counter field) of the same memory. The telephone may be adapted to display, e.g. on LCD, the number of calls received from telephone numbers stored in the memory. Hence the user can review at a glance how many times a particular caller has made an incoming call.
