We run WLCs with code version 184.108.40.206. Our 7921s run with code version CP7921G-1.3.2.
I have some 7921s that are failing. They hang at the Loading Network
Services stage of the boot-up process.
From the phone keypad, when I view the MAC address to attempt to troubleshoot the issue,the MAC address is listed as D80000000401. This is not a valid MAC address. The phone is not associated with an AP and therefore is not registered to Call Manager. I cannot find the phone by searching for that MAC
address in WCS.
