I am trying to bring up a SIP Trunk to AT&T IP FlexReach Service. I have a Cisco 2811 configured as a CUBE using the documentation at the following link http://www.cisco.com/en/US/solutions/collateral/ns340/ns414/ns728/ns784/798119.pdf. This document covers CUCM 7.1 to a 3825 running IOS _ivs image version 12.4(22)YB4 or later. I am running 12.4(22)YB8. I have CUCM 8.0.2.
The issue that I am having is that it appears that the address-hiding command is not working.
I am attaching a debug ccsip messages and the configuration.
Any help would be greatly appreciated.
