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
?
