ARQ/ACF/ARJ between Gatekeepers?

Dear all,

since the first version of H.323, the call signalling procedures have
been explained through a series of examples. Although examples do help
to get the idea on how things should work, they remain examples and
are therefore (usually) incomplete.

Take the example from Figure2/H.323v2 (or Figure 40/H.323v4): GK1 sends
the SETUP message without first initiating the admission control procedure.
If GK2 expects the admission control procedure to take place prior to
the call setup, then this will fail unless GK2 makes an exception for
certain "EPs" (GK1 in this case) to place calls without an admission
control procedure.

Are there any visions on this scenario?
