Abstract: A method and service for enabling routing of calls to a user is described. Connection rules for a user are established, and organisational or social network data is obtained from the user for use in determining a social network connection graph. On receiving a request to route a call to the user with organisational or social network data associated with the caller, a matching directory service (1) determines from the social network connection graph and the connection rules whether or how to provide call routing data in response to the request.

Abstract: A method of ordering contact information for a communications device comprises the following steps. Contact information is associated with a plurality of events associated with the communications device. A contact interaction history is determined from the plurality of events and associated contact information. Contact information is ordered on the basis of the contact interaction history. A suitable system, in which some or all of these steps may be carried out remotely from the communications device, is also described. An alternative method is described which involves determining a current communications device state and ordering the contact information for presentation in dependence on one or more variables of the current communications device state.
