A presence enabled call hunting group provides for identification of available terminals in the call hunting group using presence information. Upon receiving a request for a communication session with the presence enabled call hunting group, a call server retrieves the presence information of each terminal in the group of terminals forming the presence enabled call hunting group and the presence information of each presentity associated the terminals in the presence enabled call hunting group from a presence system that aggregates the presence information from multiple presence sources. The call server uses the presence information to identify available presentities and available terminals associated with the available presentities within the call hunting group, and directs the communication session towards one of the available terminals.
