    Abstract: A method of operating an availability service in a telecommunication system interconnecting a legacy telephone system with at least one presence system, said legacy telephone system including a plurality of terminals (T1 . . . T10), at least some (T1,T2) of which are terminals of subscribers to said availability service, said method including:(a) continuously monitoring each subscriber terminal (T1,T2) for a change of a call status of said subscriber terminal from the presence of a call to the absence of a call;(b) generating a first or "high availability" signal when said call status of said subscriber terminal changes from said presence of a call into said absence of a call;(c) monitoring an interval of time beginning with said first signal;(d) generating a second or "availability unknown" signal after a predetermined time period tau within said interval; and(e) making said availability signals accessible to any interconnected presence system.
