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.
