Abstract
A telecommunications system includes a telephone routing system; and a presence database manager unit operably coupled to the routing system and adapted to maintain one or more watcher lists of registered users. The routing system is adapted to receive phone calls and provide an indication to the presence database manager unit whether the phone calls originate from registered users. The presence database manager unit is adapted to determine if such a user has a watcher list and transmit an indication to parties associated with the watcher list that said user is present.
