Abstract (en)
[origin: WO9727692A1] A method and apparatus is described which enables users (10) of a standard telephone system (12) to access a packet-based network, such as the Internet (36). A first callover unit (32) converts signals (14) from the standard telephone system (12) into packets (34) formatted for Internet transmission. Embodiments are described which allow a voice telephone call to be placed substituting the Internet (30) for a long-distance carrier (22). A second callover unit (40) converts the packets (38) back into voice signals (24) transmittable over a standard telephone network (20) to a standard voice telephone (28).
