Abstract
A method for telephony includes modulating output audio signals produced by first and second telephones in a voice band so as to generate respective first and second upstream passband signals in a passband at a frequency higher than the voice band. The first and second upstream passband signals are transmitted to a telephony gateway, which couples the first telephone to communicate via a telephone line over a circuit-switched telephone network and couples the second telephone, via a data interface of the telephony gateway, to communicate over a packet network.
