A method and system for automatically routing a call to an identity of multiple identities based on an active presence profile. A subscription message is sent to a user's contact addresses. The contact addresses include identities of the user and indicators of remote servers that manage real time communication systems. A presence document that includes a presence status of a first identity of the user is received. The presence status indicates that the first identity is offline. A registration message is issued to a remote server, resulting in a call redirection from the first identity to a second identity. The second identity is included in an active presence profile and is associated with a computing system that receives the redirected call. If multiple presence profiles of the user are active, a matching algorithm selects a contact address of one of the active presence profiles to determine the call redirection. |
