<p>A mobile communications unit (1) that has an application (5) adapted to directly or indirectly control a non-public branch exchange (3) via a wireless telephone network (2), said wireless telephone network (2) being part of a public telephone network, said application having a client program (6) which, on the one hand, is adapted to present a graphical view on a display screen of the mobile communications unit, in which view users can select one out of a plurality of different predetermined functions or actions which the user desires the branch exchange to perform or take and, on the other hand, to generate the specific instruction which the branch exchange associates with the selected function or action. According to the invention, the application has a server program (7) that is adapted to poll a predetermined TCP socket of the communications unit, wherein the client program, when it has generated the specific instruction which the branch exchange associates with the function or action the user has selected, is adapted to send the instruction to said TCP socket, and wherein the server program is adapted to utilize a suitable API (9) in the operating system of the communications unit to call via an operator-associated SIM-card and the telephone network and forward the instruction to the branch exchange. The invention also relates to a method in such a communications unit.</p> |
