I have configured AAR IN CUCM 6.X. When CAC is implemented phones in the branch office can ring some phone at HQ but not others. The phones that they can't reach have ddi's that do not match their 4 digit dn's. These phones that can't be reached over the pstn when cac kicks in. These phones also have single number reach (might be a red herring). I have external phone number mask to represent the full ddi and I have also used the AAR MASK but it still does not work.
I am testing this using a pri tester. I can ring the number over the pstn to the pri tester in normal conditions but when cac is working the branch phone just says not enough bandwidth and as expected the pri tester does not ring.
Any ideas what I am doing wrong.
