|Interesting. Doubles the fundamental frequency of the ring signal. Cute
|idea, very efficient, inexpensive...
|Hmmm... I guess that it only works with "tuned" ringers.
|AFAIK most all ringers are tuned and so that's OK.

However it works, it works on my Home Receptionist phone which doesn't
use a mechanical ringer.
I plan to view Caller-ID (using an old PC) with the ringing
suppressed. If the Caller-ID matches my allowed list ringing will be
activated. Shit list CID's will be "answered" by the PC, given a
nasty message, then hung up ;-)
