Hi, I'm researching on how to do CAC between the cluster I manage in Sao Paulo (with two offices and two locations) and routing cluster in NJ to where our calls are redirected to other company clusters in US. Would be possible AAR to CAC my cluster to US one? Or should/must I use a gatekeeper to control calls amount? At the beginning only calls from Sao Paulo to US cluster. Later we might have incoming calls as well.
I am trying to get more knowledge on how AAR works using two test locations at different gateways (which we call FT and JK locations) and 2 7941 phones with two lines. While using a maximum of 128Kbs limit for each location, I am able complete the first call and second one fails with a Not Enough Bandwidth without AAR. Problem I have is in enabling AAR so the calls re-route to PSTN. I keep getting same lack of bandwidth message. My CUCM is 4.2(3). While looking at book resources, it's advised to place each DN in their own AAR Group, but I cannot see this line/field. Only at the device settings I am able to use AAR group and associated CSS. Any tips on what I am missing?
Thanks a lot.
