I suggest you look at the stage 2 documents for ISDN (Q.84.2through5 from
memory - its somewhere around there anyway). You will find that the
originating exchange receives all information about each forwarding hop
(step by step as it occurs).
The forwarded to exchange gets the original and last forwarding numbers.
Whether these are presented to the end user depends on the wishes of the
calling and forwarding users.
