The invention provides a method of authorizing provision of in-directed content to a user of an IPcommunications network. The in-directed content is associated with a presentity subscriber of a presence service, the presence service including authorization rules regarding users to which the in-directed content may be provided. The in-directed content is stored at a content server that is not controlled by the presence service. The method includes receiving at an authorization proxy in the network a request from the user to be provided with the in-directed content, and identifying the presentity subscriber associated with the requested in-directed content. The authorization proxy retrieves the authorization rules to verify that the user is authorized to receive the in-directed content. Subject to the verification, the in-directed content is provided from the content server the user.
