Abstract

Methods and apparatus for allowing a caller on a telephone network to establish an internet co-socket. In a first embodiment, a protocol stack establishes an Internet connection over a public switched telephone network (PSTN) link and then operates and maintains the Internet connection on a second link. Internet socket establishment is initiated with a caller-ID packet so the distant end may pick up with an Internet form instead of a interactive voice response system (IVR). This allows the caller to interact with a graphical form instead of a voice prompt, and provides new methods of operation for web call-back systems for call centers. The invention also enables mixed PSTN/internet multimedia telephone calls. In an exemplary embodiment, when a point-to-point telephone PSTN connection is established, a screen of information automatically appears at both ends via the Internet. This allows users who have computers connected to an internet to easily mix PSTN calling with internet services.
