Hi,

Thanks for the reply.

This supports my guess that it was inserting the default because
specific bandwidth info was not in the Setup message.  

But I'm still confused. Because A level 5 GnuGK trace AND a tcpdump both
indicate that the registered called party sends an ARQ with the correct
bandwidth request immediately after receiving the proxied Setup message
from the GK.  Wouldn't this indicate that the BW request is available in
the Setup message?

It appears to go as follows:

1) GnuGK receives an LRQ from a Cisco MCM GK.
2) GnuGK sends an LCF to the Cisco GK.
3) The "unregistered" endpoint (registered to the Cisco GK) sends a
Setup to GnuGK
4) GnuGK SqlAcct does a StartQuery INSERT with the default BW 1280.
5) GnuGK proxies the Setup to the locally-registered endpoint.
6) The called endpoint sends an ARQ to GnuGK with the correct bandwidth
request (7680).
7) GnuGK sends an ACF to the called endpoint.

Then the called endpoint sends Alerting and Connect msgs and the call
proceeds as expected.

BTW, I would update BW on a StopQuery UPDATE, but I need the correct BW
available to query while calls are active for a bandwidth-based CAC
scheme I've cooked up.  It works for calls between locally registered
endpoints and when local EPs call unregistered EPs.
