ABSTRACT:
Systems, methods, and apparatuses are disclosed for providing Internet Call Waiting (ICW) Messaging Services. In an embodiment, a calling party places an incoming call to a called telephone number having an active ICW session and data connection. A telecommunications system allows a calling party to communicate an ICW message to a computer system engaged in the ICW session and data connection. The telecommunications system may also allow a called party (e.g., the user of the computer system) to communicate a response to the ICW message and, thus, allow interactive ICW messaging.
