Ok, what is NDI and NDS?

In some countries, France included, you do not have just an ANI associated with a POTS line.
You have one "head of installation" number, that is specific to the global setup of a telco customer, and then specific ANIs for each endpoints.
This is a problem in several protocols, because usually only one field exists.

Also, in SS7 peering with PTTs in some europpean countries, you need both numbers because only one of them is authoritative for identifying the line (then "installation ANI"), as the other one can be user-specified.

Think of it as a billing identity and a caller-id.
