Outgoing call log data associated with a call from a subscriber's terminal is provided by a system including a switch, which receives the call from the subscriber's terminal and launches a query in response to the call, and a service controller, which receives the query and forwards call data to an interface server in response to the query. The switch continues to process the telephone call after querying the service controller. The interface server obtains additional information from a directory database based on at least the received call data. An outgoing call log database receives and stores the call data and the additional information from the interface server as the outgoing call log data. A web server retrieves the outgoing call log data from the outgoing call log database, in response to a query from a web client, and displays the outgoing call log data at the web client.
