A communications system is disclosed in which a mobile telephone has associated primary and secondary telephone numbers and a communication apparatus has an associated steering telephone number. The communication apparatus receives from the mobile communication device, via the steering telephone number, a request for communication. The request includes the primary telephone number as a source telephone number. The communication apparatus determines, from the received request, a destination number of a further communication device; updates the request to include the secondary telephone number as the source telephone number; and sends the updated request towards the further communication device. |
