Abstract
A method for selectively enhancing a voice telephone call from a first location to a second location over a public switched telephone network, including receiving audio signals from a conventional telephone using a first device positioned at the first location; and, in a first mode, passing the received audio signals to the public switched telephone network in a substantially unaltered manner; and, in a second mode, generating data indicative of the received audio signals using the first device; multiplexing the generated data with other data desired to be communicated using the first device; and, transmitting the multiplexed data over the public switched telephone network; wherein, the transmitted data is suitable for being received from the public switched telephone network and de-multiplexed to generate reproduced audio signals indicative of the received audio signals and the other data by a second like device.
