Audit capabilities tells you what the capabilities of the system
are.  Audit Value tells you what is currently "in use".
In theory, the "1000 G.711 channel resource" comes from Audit
Capability, "500 busy" comes from Audit Value.

In general, the RFC is compliant with the requirements with one
notable exception: many gateways are implemented with DSPs or other
programmable resources. There is no good way to express capability
with such resources.

If you have 1000 fixed G.711 channels, Audit Capability will reveal
that.  If 500 channels are used, Audit Value will reveal that.
