Brian,

I meant that in the scenario all of N1, N2, N3 are pure sigtran-nodes (i.e.
no SS7 nodes in the network), is there any usecase when transferring
messages from N1->N3 in the configuration ::

              * IPSP-IPSP association between N1 <-> N2
              * IPSP-IPSP association between N2 <-> N3
              * GTT at N2

will have ANY different behaviour (from pure end-user point of view)
against the configuration ::

              * ASP-SGP association between N1 <-> N2
              * SGP-ASP association between N2 <-> N3
              * GTT at N2

?
