The invention relates to a function control system (1) in which a function practitioner (4) included among a plurality of available function practitioners is able to report his/her position and/or customer-related function to a common unit (3) via a telephone network (2) for control purposes, wherein said unit is adapted to handle communication from a mobile telephone apparatus (4a) belonging to respective function practitioners. 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 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. The common unit (3) thus registers at least the function practitioner (4) and the customer (10) connected via a signal exchange relating to said control signals associated with the call and generated in the telephone network.
