Abstract: A method includes receiving, from an external presence server at a proxy presence device, a presence status request for presence information associated with a user device in a home carrier network. The method includes sending the presence status request to an internal presence server in the home carrier network. The method also includes receiving the presence status of the user device and storing the presence status of the user device with a time to live (TTL) in an associated database. The presence status is sent to the external presence server. The method includes receiving at least one subsequent request for the presence status of the user device within a time window of the TTL. The method also includes sending the presence status within the time window of the TTL without sending another presence status request to the internal presence server.
