resources available on a h323 gateway ?

[Baker, Maurice R, ALNTK]

You may want to check ITU-T Rec. H.225 with respect to the "RAI"
(ResourcesAvailableIndicate) RAS message.  Per a copy of the document, 'The
Resource Availability Indication (RAI) is a notification from a gateway to
its gatekeeper of its current call capacity for each H-series protocol and
data rate for that protocol'.  While my hardcopy (admittedly likely to be
rather out-of-date) of the Rec. looks like the major required information
defined to be conveyed is a simple "almostOutOfResources" field set
accordingly to true/false, there is also the companion "nonStandard Data"
field which could be used for a greater level of detail [albeit in a
proprietary manner].

No doubt there has been further work & evolution in this area, but that
could be a good place to start.

Many implementors are relying upon number of ports on a gateway to charge
for licensing (one license per port).  Does H323 support a message (from the
H.323 gateway to the Gatekeeper) which advertises number of ports/resources
available on the gateway , say upon gateway reboot or restart ? By gateway
port, I mean the termination of one circuit (one channel on a T1, for
instance).

MGCP has a RSIP (Restart In Progress) message which solves this dilemma.

Any help would be appreciated.
