Caller Control of Internet Call Waiting (ICW) Services are provided to disconnect an active ICW session and data connection and to prevent establishment of a subsequent data connection. In an exemplary embodiment, a calling party places an incoming call to a called telephone number having the active ICW session and data connection. The calling party may enter an authorized code that authorizes disabling of ICW and the data connection.

The telecommunications network verifies that the interrupt code to enable caller control, and, thereafter, disables the ICW session and data connection.
