A REN extender? I have a BT one of those: RS used to sell them years ago. They take a 75V 25Hz signal and regenerate it, rather than supply a 25Hz ringing current from d.c. but yes...
An external mains supply is needed, of course.

Just noticed the reply. Not an extender( convertor ringing xx )as such- but a normal looking large size socket, with ringing circuitry inside , powered by 50 v DC from a BT system .
