[net.analog] Telephone Ring Disable

jwk@galbp.UUCP (John Kish) (11/09/85)

I am looking for information or pointers to information on telephone ring
control.  What I want is as follows:

	A device that can be plugged into a standard modular phone jack
        that is capable of disabling the ringing of all telephones while
        still getting a ring indication itself.  However, it also needs
        to have the ability to ring the other phones if the call is not
        for itself.

This may or may not be possible, I don't really know.
Mail me any ideas or sources of ideas.
Thanks,
