Abstract: In one embodiment, a method for unifying rosters is provided. A client receives an escalation request associated with a first roster and responds to the escalation request. The client subscribes to the first roster as a participant in response to accepting the escalation request or subscribes to the first roster as an observer in response to denying the escalation request. The client identifies a second roster within the first roster that the client is not subscribed to and subscribes to the first roster as an observer. The client updates an entry associated with the client in the second roster to indicate that the client is subscribed to the first roster as one of a participant or an observer. The client additionally updates an entry associated with the client in the first roster to indicate that the client is subscribed to the second roster as an observer.
