A method of distributing telephone and/or telephone subscriber status/availability
information comprises receiving information at a relay centre from each of a multiplicity
of status/availability terminals. This information corresponds to the status/availability
of a telephone and/or telephone subscriber and/or telephone line associated with
the sending status/availability terminal. Information received at the relay centre
from each sending status/availability terminal is immediately relayed to a group
of other status/availability terminals associated with the sending terminal. At
each receiving status/availability terminal, the received status/availability information
is displayed on a display of the terminal to advise the subscriber of the current
status/availability of other subscribers in which he is interested.
