US Patent 7304983 Methods and systems for enhancing internet call- waiting messages

Methods and systems are disclosed for notifying a called station of an incoming call. The called station has a busy status as a result of a connection to a data network via an access server. Because the called station is connected to the data network, and thus “busy,” the method receives an Internet Call-Waiting message from the access server. The Internet Call-Waiting message includes information representing the telephone number of a calling station. The method queries for additional information representing the calling station, and the method presents the telephone number and the additional information to a user at the called station. The telephone number and the additional information notify the called station of the incoming call.
