To check the status of an agent assigned to a call center in which geographic areas are respectively associated with geographic area identifiers (IdZ) communication terminals (TC) are respectively associated with geographic areas, a mobile terminal (TM) in possession of a monitor capable of moving within geographic areas determines the geographic area's identifier within which an agent is located. The mobile terminal transmits a request comprising the geographic area's identifier to the data management server in order to retrieve from a lookup table an identifier (IdA) of the agent associated with the geographic area's identifier, and transmits a request comprising the agent's identifier (IdA) to the call center's server (SCA) in order to retrieve from a lookup table the identifier of the agent's status data (DonA) associated with the agent's identifier (IdA), then provides the agent's status to the monitor through graphical display based on the agent's retrieved status data (DonA).
