Magic Jack and a lot of other dial tone 'gadgets' don't generate the voltage and loop current required. Most 1A2 hardware was designed and built around working behind real central offices, not these substitutes. A 2565 is no different from a 2500 set electrically, but it still requires 48 volts on the line to function within specs. since the dial receives its power directly from the CO line. Last I checked, the Magic Jack device only provides a loop voltage somewhere in the 12 volt range. Cordless phones or systems that require external power to function are able to function better in these low voltage conditions since the tones being sent are generated internally, and not dependent upon loop voltage to operate.

All hope is not lost, however. There are some loop line extenders that will condition the line so that it delivers the proper voltage and loop current characteristics.
