1. A system for telephony, comprising:

  • a plurality of telephone adapters, each of which is configured to be coupled to a telephone and to modulate output audio signals produced by the telephone in a voice band so as to generate upstream passband signals for transmission in a passband at a frequency higher than the voice band, and to receive and demodulate downstream passband signals so as to generate input audio signals to the telephone; and

    a telephony gateway, which is adapted to receive and demodulate the upstream passband signals and to generate and transmit the downstream passband signals to the telephone adapters, and which comprises a line interface for coupling to a telephone line of a circuit-switched telephone network and a data interface for coupling to a packet network, and which is operative to process the passband signals so as to couple a first telephone, via a first telephone adapter and the telephone line, to communicate over the circuit-switched telephone network, while coupling a second telephone, via a second telephone adapter and the data interface, to communicate over the packet network.
