Abstract

An approach for providing an on-line directory assistance services is disclosed. An on-line directory assistance system includes a server that receives a request message for information over a packet switched network from an access device. The server forwards the information to the access device in response to the request message, wherein the information includes basic content data and optional enhanced content data. The system also includes a database that stores the information. Further, the server selectively receives a modification message to modify the enhanced content data associated with the information from the access device. The server then updates the database based upon the modification message.
