Automated booting of a client for a subscriber is provided for clients that are for use in interactive user sessions that involve multimedia. A subscribe message is sent from the client to a proxy server. The proxy server authenticates the subscribe message, and sends the subscribe message to the configuration server. A notify message is sent to the client from the configuration server. The notify message is sent through the proxy server, and contains a location of a profile for the client. The profile is downloaded to the client. This arrangement allows the persistence of profiles in a centralized place.
