First Ring Supression? Kris Jacobs 01-05-2006

I have a single POTS line in the house.

I have 1 drop going from the demarc to the house phones.

I have a second drop going to a modem attached to a PC, running caller
ID software.
This software will read CID info, and then take action on the call
based upon how I have it configured. If the software blocks the call,
I still hear that single ring on the house phones. I don't want to
hear that first ring.

I want to *always* suppress the first ring on the drop to the house
phones, then subsequent rings can go thru to the house phones. The
house phones have no Caller ID functionality, and do not need it.

The drop to the modem and computer will sense ring #1, read CID, then
either stop processing and leave the call alone to keep ringing, or
pick up the line and play a short message stating the call is blocked,
blah blah, whatever - or just pick up and then hang up.
The software checks the CID info and does 2 different things:
Logs the call and leaves it alone
Intercepts/blocks the call before the 2nd ring.

This system is all working great right now - the software is doing
exactly what I want it to do. I just have this little annoying issue:
if the software ends up handing the call, I still hear that 1st ring on
the house phones.

How can I always suppress ring #1 on the drop to the house phones?

Thanks!

On your modem is a phone out connector, can you run it back to the demarc
point for the rest of the house phones? So the telco will go to your modem
which detects the CID on the first ring and it should pass it through to
the house phones. Might work.

Hopefully yes.. The modem's telco in port connects to the phoneset out port
via a relay. When the modem answers, the relay disconnects the phoneset.
The more I think about it - it probably won't unless the modem picks up on
the first ring and then drops it - which wouldn't happen. Damn sounded good
for a second. Easy way to test is plug a phone into the modem and see if it
rings.

Why not apply for callerid block if you have it in your area? This lets you
set up a listing of call id strings that will not be allowed through.

If I remember right the old Microsoft Cordless phone used to do this. You
could block a particular call id string and from that point forward it would
not even ring the phone when that person called and send them directly to
VM.

It only suppressed calls on that device though. If you had other phones
connected to the same line they would still ring.
