I am working on a Call Manager 11.0 cluster where they have working 7925 phones in their Aruba wireless. They recently purchased a single 8821 phone and we have been experiencing multiple issues. The first issue is that the phone will lose it's registration and when it does the phone will reboot. Additionally we have seen several times where the phone will go to a black screen with the message Device has Crashed in red letters. We have upgraded the phone to the latest 11.0(3) firmware, but the issue is still persistent on the phone.
Has anyone ever run into this type of behavior?
Thanks,
Michael
