In connection with a customer (10), the function practitioner (4) shall activate, via his/her mobile telephone apparatus (4a), a call, via the telephone network (2), to said common unit (3), which is adapted to receive and register control signals sent 4a from the telephone network, said signals having the form of ringing signals originating from the call from said function practitioner (4), and to register selected criteria relating to the call concerned, such as A-number identification, B-number identification, and/or the time at which the call was received.

Abstract: The invention relates to a telecommunications system that includes a number of calling subscriber apparatus (5), a number of telephone exchange units (1) and a number of called subscriber apparatus (8). The system is adapted to enable a call incoming from a selected permanent system-associated subscriber apparatus or a mobile system-associated subscriber apparatus to be transferred to a selected permanent subscriber apparatus or a selected mobile subscriber apparatus, through the medium of a selected telephone exchange unit and its associated computer equipment. Subsequent to having received a call, the telephone exchange unit (1) and/or the computer equipment (10) establish or evaluate the geographical area and/or location of the calling subscriber apparatus. The telephone exchange unit and/or the computer equipment evaluate, establish and store the geographical areas (21a-21d) and/or locations applicable to each of a number of available subscriber apparatus.
