[asterisk-biz] ANI

[Trixter aka Bret McDanel]

remember that the ani should be the customer, many banks use this for
authentication purposes (for example when you get a new credit/debit
card).  This was one issue vonage had because they set caller id but the
ani was of their number and it causes a lot of consumer frustration.

There are legit reasons to set the ani to the customer and not the
provider, especially for those that want to use it as a pots line
replacement service.

ideally it would be the number that the customer chooses that they have
proven is theirs.  However this becomes harder when you get resellers of
resellers.  You also have to have a database, which is checked for each
and every call to see if that customer is allowed to dial out with that
ani.  This increases the switching cost to set up the call, increases
the overall costs in terms of maintaining that database, and is not
infallable (a customer may have the number one day and not the next).

If it boils down to a fine, you can have a indemnify and hold harmless
clause but for those to really be effective you have to have the person
in a jurisdiction where they can be served and be forced to comply,
which makes international customers difficult, it also means that they
have to have enough to actually pay, if they dont you are still on the
hook for the fine.
