Detecting whether an idle phone is attached to a POTS port isn't exactly 
trivial.  This is more true now with modern phones that don't have 
mechanical ringers.

Keeping the ethernet port up on battery if there is link makes sense. 
For that matter a "Wake-on-LAN" style polling to power it for a second 
every 30 to detect carrier would be even better.
