Anyone have a favorite circuit for a remote telephone ringer?
I have access to the phone line, but no close-by source of power, so
telephone line-powered or low battery drain.
Commercial purchase also OK.
Suggestions?

Why don't you just get a corded phone? They're cheaper than the
'remote ringer' thingamabobs and have the added 'feature' you can
answer the call.

I being slightly evasive :-) I need only the ringer, for devious
purposes :-)
But your catch is certainly the cheapest. Thanks!

You should not spy on your spouse and children.... 
Nope, here's my G-job problem:
800 Number reject boxes blank the first ring. Which keeps you from
seeing CID on your phone.
It occurred to me to use an 800 Number reject box simply as a
controller to disconnect the line from the house phones, let it ring
X-1 times, where X = number of rings to roll to voice-mail, then
seize, then hang-up ;-)
Then, to keep that first ring activating CID on the phone, turn off
local ringer (doesn't stop ringing voltage from initializing CID)...
but add ringer that doesn't ring until the second ring (so that I know
phone is ringing :-)
Devious path to success, eh what ?:-)
(Existing reject box designers haven't yet figured out how to insert
CID after second ring. Shouldn't it be easy enough with a micro?? )
