Hi Cyrus: I could not find any other solution, is the way it works, when is one zone and you have an specific CAC requirement, I would suggest to use the interzone command, however for one zone it does nothing. Regards, Jose

BACD needs at least 144 to work properly. The reason is with BACD u have one 16k call (if using G729 over wan) and one 128K call (this is caused by CME ARQ to GK) The question is if requirement be like that : -the minimum configuration lines to GK work properly ---------> so 1 zone should be used -use cac to limit your call to sth less than 144 - run BACD on CME Is there any way to accomplish this? I couldn't find a way myself. It would be great if someone comes up with new idea to do this On Thu, Jan 15, 2009 at 2:39 AM, Jose Gregorio Linero (jlinero) <jlin...@cisco.com> wrote: Hi Chris: The problem is that the router that is registered to the GK sends an ARQ to the GK, and due to the fact you have configured bandwidth total with a value less than 128k the call is rejected. The question is, why, if we are using a dial peer with session target a loopback IP address, does it send an ARQ to the GK. I was reading a lot trying to find the answer, and it is not a bug, it is the normal behaviour, the recommendation for a one zone GK when yor are required to do CAC is to configure at least 128k, when you have more than one zone, you have to use the interzone command, and generally, when you have a single zone there is no CAC requirement. Maybe Vik have another point of view, but that is what I found when I saw this problem first time.

So I must be running into this issue. I do have bandwidth total configured on my GK as well. It is set to 96. I'm guessing if I bump it up to 128 to allow a g711 call it'll work?
