I've got the specs for a program to use with your modem to generate what'll resemble a full CID. So with the computer set up to dial, even standard voice calls too and faxes, too, can be equipped with a fake field (or "header" if you will), displaying a homemade caller ID.
Since it uses the exact same structure as the real caller ID, no telco along the entire system will ever doubt it. I can send the full specifications if you are seriously interested in doing the code in full or in part. Sorry, I can't implement it myself (lack of skills).
I, for one, would be *very much* interested in receiving the specs and any additional information you could provide.
