Abstract

Methods and apparatus for allowing a packet data connection to be established by sending an indication of a network address through a telephony path. In a first embodiment, a protocol stack initiates the establisment of an Internet connection by sending a data segment through a public switched telephone network (PSTN) telephony path and then operates and maintains the Internet connection on separate packet connection. Dialing digits are used to indicate the address of a remote computer or wireless device via the telephony path. This 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 one or both ends of the connection via the Internet.
