Such devices exist at Radio Shack.

You need the X-10 telephone responder (RS's name for X-10 is "Plug-n-Power").
The telephone responder can activate any unit#. The unit in question
can be either an appliance module (for switching 120VAC or 220VAC), or
the relay output module (I think they call it a burglar alarm interface).
