We are presently reviewing QoS support in H.323 and a new Annex N to H.323
is in preparation. The current H.323 assumes homogeneity of network
transport and QoS mechanisms so the only issues to be considered in H.323
are what type if QoS mechanism is supported in the end point. The new work
recognises that transport may involve a variety of transport mechanisms e.g.
ATM, IP FR, as well as QoS mechanism, e.g. RSVP, DiffServ, MPLS, some of
which may be hidden from the end user.
Maybe other experts could comment on your specific query.

How it should be interpreted since it seems there is nothing
