I think it would be possible to use an Asterisk system to simulate the Eaton dial-home service and allow the modem to call home once again. This would only have historical significance for anyone who wanted to know what their base station was reporting to Eaton back when the dial-home service was operational. However one would probably have to dump the firmware on the base station to find out what the modem was expecting during the “conversation” in order to coax out info after the dial-up was successful. The time spent hacking on the modem would probably be better off making it do something else entirely different though. What that would be I have no idea yet.
