Hi,
I have a similar issue. Few phones of my deployment work for some days and suddenly begin to frequently restart and unfinite cycle in registering to cucm and then rebooting.
I have 8841/8845 Phones and 802.1x authentication by certificate.
Did you get solved your problem?
Best regards
Manfred

Hi Manfred, I have a couple of questions:
1. What type of switch and version of code are you running?
2. Do you have idle and/or re-auth timer configured in your authorization policy for the IP Phones
Thank you for rating helpful posts!
