I believe that a fax modem can be set to "wake on ring". Look at your machine (inc BIOS) and see what you can find? L

voice modems can be set to wake also. as far as an actual physical device, you could easily program a microcontroller to poll the line voltage and move a servo, or just wire it to the on switch to close when it detects a number of rings within a certain time.
