[asterisk-biz] ANI

[Miles Scruggs]

I don't see how that wouldn't apply since there still exists a calling  
party and receiving party, and carrier.  Since the question was of  
spoofing it wouldn't make much sense to think of spoofing happening on  
the receiving end.

You simply have no assurance that the ANI/CID you are receiving is in  
fact valid. It is suppose to be but that is as far as you can go.
