My customers would have something like Netmeeting. They would
make calls with an area code, say like 1-408-555-6666.

Let us say I have GW1 and GK. GW1 supports area codes 408 and
409. It registers these two voice call prefixes (1408 and 1409)
with GK along with port numbers 2000 and 3000. Any incoming
calls on port 2000 are automatically assumed to be outgoing
calls to area code 408 (so that GW1 need not again parse the
calledPartyNumber in the incoming message). Parsing of the
remaining number would be done at much later point in time.

Now, when a call originates from netmeeting, the ARQ would contain
the destination telephone number (1408555666) in the
"destinationInfo". GK receives this ARQ and figures out
that it has GW1 which registered the prefix 1408. So, GK returns
the <GW1 IP Address + 2000> to netmeeting. And netmeeting would
directly send the Q.931 SETUP message GW1's port 2000.

This is what I am looking for.
