      bandWidth 160

      callModel direct : NULL

Showed the site is registered.  Site was pingable.  I rebooted GK.  Waited 20 minutes and saw no site registration into GK but it eventually registered.

Re: HELP: Gatekeeper admission confirmation (ACF) message missin

See below for some of the requested info.  We fixed it by rebooting the H323 TERMINAL.  Even though GK showed TERM registered (and pingable), for some reason GK would not respond back with an IP of the TERM in the ACF message.  The GK should've aged out the terminal if it wasn't a valid registration anymore.  Since its working now, I cannot get you a full trace of all the information requested.  The ACF message I posted was the actual message when it failed.  I did not include all of it since it wasn't relevant.

Re: HELP: Gatekeeper admission confirmation (ACF) message missin

Correct..GK shd have flagged it or forced unregister the terminal

if there was an issue with TTL or Reg refresh.

But ofcourse that didn't happen. If GK was infact seeing it as

registered, it shd have returned proper IP address in the ACF.

So I agree some sort of glitch on the GK. If it happens again,

please do capture info requested.

Also, do u know if the  terminal supports h323 ver v1 or a v2 ?

What do u see for TTL in RRQ ?
