The NP query can be done at various points in the network such as in the
PSTN or in the h323 network. In h323 network, it could be by the GK or
GW(ways of doing this is beyond the scope of the standard - H.460.2).

In real world, mostly it'll be done in SS7 network outside the H.323
network or by the H.323 GKs.
