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.

Description

BACKGROUND OF THE INVENTION

[0001] 1. Field of the Invention

[0002] This invention relates generally to the integration of telephone and internet services and protocols. More particularly, the invention relates to a system whereby an internet co-socket may be associated with a standard telephone call.

[0003] 2. Description of the Related Art

[0004] Call set-up technology used to establish telephone connections across the public switched telephone network (PSTN) is well known; several call set-up strategies for Internet telephony are emerging. Multimedia telephony is also emerging whereby various types of multimedia calls may be established to carry voice, video, and data. Multimedia calls are traditionally expensive and often consume large amounts of bandwidth, especially if real-time video is involved. Multimedia calls are also traditionally more complex to establish and often require technical support personnel to run specialized multimedia telephony equipment. One form of multime...
