->does anyone have a design for a cct that shorts ring current and is switched
->by the pc?
->this would be _very_ handy when combined with caller id software as the
->phone will not ring until the software has decided the caller is not
->blacklisted.

-I posted a question about a Radio Device awhile back... it simply had
-a full-wave rectifier between TELCO and the Phone to prevent ringing.
I tested it. Works like a champ. However that isn't the hard problem as the OP has pointed out.

-This could be implemented with a relay instead of a slide switch to
-allow PC control.

-The Caller-ID mechanism *must* be on the TELCO side... I tried it
-after and the CID data can not be seen.
Exactly the problem. All the phones in the house have CID devices and you want to pass the CID info to them. However you don't want the phone to ring until the call has been whitelisted. I wonder if phones will accept CIS info without the first ring? Then maybe the CID info can be passed though while the ring is filtered.
Not exactly an easy problem.
