Abstract
If telecommunication devices in a group are associated with different network technologies, a use status of one telecommunication terminal in the group is still transmitted to a second telecommunication terminal of the group. Thus, for example, a busy signal is output by one device of the group even if the telephone call is conducted using another telecommunication terminal of the group.
