<p>A communication system (1) for example a voice and/or data system, has at least one user terminal (T1 ... Tn), a facility providing processing device (2) coupled thereto for connecting the user terminals (T1 ... Tn), and an intervening network (3) for interconnection of the processing device (2) and a remote user terminal (RT1 ... RTm). The intervening network (3) is arranged for conveying at least facility related signals (S), and the processing device (2) is equipped for allowing its facilities to be used by the remote user terminal (RT1 ... RTm). An appropriate signalling protocol, such as with DTMF tones can be used to communicate the facility related signals (S) through the intervening network (3), between the processing device (2) and the remote user termnal (RT1 ... RTm).</p> |
