Abstract: A telecommunication system is described which comprises at least a first and a second end station. The first end station enables intruding on the second end station if the latter is in a busy mode by sending an intrude message to the second end station. The second end station is configured for reproducing the intrude message. This makes it possible to intrude without disturbing the call being held by the second end station.

Abstract: A telecommunication station having the capability to both block selected incoming calls and transfer other selected incoming calls. The station further has the capability to provide user messages to the blocked calls and thereafter, if desired, further divert the blocked calls to another selected station.

Abstract: A communication terminal for use in a communication system comprises a display unit having a display screen onto which call states of different terminals in the system are represented by means of icons of different sizes and shapes, depending on the current call state of the terminal itself and the call states of other terminals in the system, in a quasi three-dimensional communication scene so as to graphically represent and distinguish terminal users involved in a communication scenario, displaying of the icons being such that a terminal user of the terminal perceives a substantial change of the communication scene upon call state changes of the terminal and other terminals in the system.
