5. A system as claimed in claim 4 , wherein said user conflict resolving (UCR) agent selects as said single rule one of either:
a most specific one of said user preference call handling rules having more conditions than other ones of said rules, in the event that said rules have different numbers of conditions;
one of said user preference call handling rules having more specific conditions than other ones of said rules, in the event that said rules have identical numbers of conditions;
a most recently created one of said rules; or
a randomly selected one of said rules.

7. A system as claimed in claim 6 , wherein said communication network is a PBX connected to the public switched telephone network (PSTN).
8. A system as claimed in claim 1 , wherein said user interface includes windows for login, user preference rule setting, context setting and message display.
9. A system as claimed in claim 1 , further including an event handler between said user interface and said application level for directing events from said user interface to appropriate modules of said application level.
10. A system as claimed in claim 1 wherein said shared database is a tuple space and said assertions are tuples.
11. A context aware call handling method according to user preference call handling rules, comprising:
receiving an incoming call from a caller to a user;
monitoring current context of said user;
applying said user preference call handling rules based on said user context and said call information,
a user setting at least one caller relationship to said user;
applying said user preference call handling rules based further on said at least one caller relationship;
setting said current user context and said user preference call handling rules as tuples in a tuple space;
receiving a notification of said incoming call and in response generating agent processing requests as tuples in said tuple space; and
receiving said agent processing reguests via said tuple space and in response assigning at least one relationship between said user and said caller, retrieving said relationship between the user and said caller and said current user context, and selecting a single one of said user preference call handling rules based on said relationship.
12. A method as claimed in claim 11 , further comprising:
a user creating and maintaining a list containing information about individuals and relationships between said individuals and said user;
a user defining a relationship hierarchy between said individuals and said user;
a user setting a schedule; and
a user setting preferences for call handling based on one or more or said buddy-list, relationship hierarchy, and schedule.
13. A method as claimed in claim 11 , wherein said step of selecting said single one of said user preference call handling rules further comprises selecting as said single rule one of either:
a most specific one of said user preference call handling rules having more conditions than other ones of said rules, in the event that said rules have different numbers of conditions;
one of said user preference call handling rules having a more specific conditions than other ones of said rules, in the event that said rules have identical numbers of conditions; and otherwise
a most recently created one of said rules.
