QTelNet (www.qtelnet.com) IP phones can be programmed to send a predesignated security code. I am not sure if this is the same deal as you are talking about, but I have set a client up that is doing a pre-paid LD and the phones are programmed to add security digits behind the scene so that they know what to invoice that phone for.
