<DIV>
<DIV>I'm going to attempt to sum up things discussed on various lists.</DIV>
<DIV> </DIV>
<DIV>ANI and CNID are two different things, though are often the same
number. BTN is yet another item that may or may not be the same.</DIV>
<DIV> </DIV>
<DIV>ANI can be spoofed, though details not revealed on list for obvious
reasons.</DIV>
<DIV> </DIV>
<DIV>Toll free, premium (900), and 911 numbers receive the ANI since
one of them is being billed for the call and the other is billing for services
rendered. That's why collection services and private investigators have
you return calls on a toll free line.</DIV>
<DIV> </DIV>
<DIV>You need SS7 or someone above you that has SS7 to set ANI as CNID to
view the ANI.</DIV>
<DIV> </DIV>
<DIV>Some people think there should be regulation against ANI manipulation,
others don't.</DIV></DIV>

<DIV><FONT face=Arial size=2>Is the CID of a call to a toll free number
really the ANI, therefore not spoofed or blocked?</FONT></DIV>
<DIV> </DIV>
<DIV><FONT face=Arial size=2>Someone who's opinion I respect said it
generally is, but he wasn't sure. Since I have a potential customer
coming to me with an ANI requirement, not a CID requirement, I figured I
should make sure.</FONT></DIV>
