Ring voltage is required to "arm" CID acquisition.

It doesn't have to hit the ringer, though.

Nope. But that operation has to be accomplished at the telephone, not
at the service entrance unless...

"Replicate" is straight forward? Explain.

Replication solves some issues, creates others, such as coping with
desired "features" such as call forwarding and voice mail.


You are trying to make it too complicated.

Disable the ringers and connect ALL of them to a spare conductor in
the four conductor station wire. (Yellow or Black wires.) Then connect
it to the line when you want the phones to ring. Process the CID. If
you want the phones to ring for that call, close a set of relay contacts
to activate the ringers. If the call is to be ignored, use another
relay to to put a 600 ohm resistor across the line for a few seconds to
answer, then drop the call. A third relay could redirect the call to
your answering machine.

If you need them, there are external ringers that can be used to let
you know a valid call is waiting.
