    Patent number: 8487770
    Abstract: A method and apparatus are provided that evaluate a number of different sources of presence information to determine a presence status of a user. The presence status of a user is determined by obtaining presence information from a plurality of presence data stores; translating the obtained presence information from at least one of the presence data stores into a standard format; and determining the presence status of the user based on the obtained presence information. Presence information can also be based on user-specified rules.
