Joe: "I don't know if there is any way for a modem connected to a circuit switched line to detect if the data is being sent, in order to conserve bandwidth. I doubt it." Yes there is, at least for satellite modems. ViaSat has the best product in the DAMA category(Demand Assigned Multiple Access). Absolutely ingenious technology to conserve precious satellite bandwidth.

Dear Josef: Valueman's comment addressed how bandwidth can be saved for satellite telephony. For land lines, there is no incentive, since in old-fashioned switched circuits, once the connection is established, it remains reserved for the call. However, this is not the case for wireless telephony, where voice activity is monitored to save bandwidth. This is also true of voice over IP. In fact, one of the big savings of voice-over-IP is its ability to use speech compression to significantly decrease the amount of transmitted data. Best regards, Bernard Levy
