Abstract
Apparatus and methods are provided for selectively providing telephone service that is either PSTN-based on Internet-based using a standard analog telephone circuit. In a first embodiment, the apparatus comprises a hardware module and associated software for coupling a personal computer or Internet appliance and a standard analog telephone. The apparatus includes a DTMF interface circuit, a subscriber line interface circuit, a ring detection circuit, and an interface circuit for interfacing with the PC or Internet appliance. The apparatus permits the analog telephone to be toggled between an Internet-based telephone mode and a PSTN-network mode by inputting a predetermined sequence of DTMF digits. In alternative embodiments, the apparatus comprises a processor, modem and optionally, analog telephone circuit, to provide a stand-alone or partially-integrated device capable of selectively switching between PSTN-based and Internet-based telephony services.
