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.

Dynamic presence proxy for call sessions

An Accessing Busy Resources service is adapted to receive subscription requests from clients for notification of when a busy resource is free, and to monitor network resources to determine if they are free. Upon notification, the Accessing Busy Resources service de-subscribes the client. The network client devices include Access Request units which make requests to access services and receive notification when the services are available.

System and method for accessing busy IP network resources

A voice message system utilizes presence status information obtained from a presence server in playing inbox greeting to incoming callers. The presence status can indicate the actual presence or availability of the called user and is thus dynamic in nature. By using a voice message system to reflect and relay the presence status, the presence status information can be heard by those devices which do not have the capability to display presence information.
