Had to call a couple of credit card companies yesterday and noticed that they went through the second automatic security step of asking for a birth date.

This has only happened when I've called from a payphone before. It usually avoids that step because it recognizes the caller id.

Does voip.ms not pass the caller id when calling a toll-free number? I have premium toll-free routing selected.

Yes it passes the Caller id. Is yours accurate?

It could be that the credit card companies are looking at ANI, not Caller ID. I don't have a POTS line handy to test with it but I seem to recall that ANI is always the same as the phone number for POTS lines, but not VoIP lines. If I'm correct, ANI can't be spoofed like Caller ID can.

Anyone please correct me if I am remembering the details wrong.

Here is more information about ANI. I found the bit about bill collectors particularly interesting; what an innovative technique.
