NO JOY Errors on Aastra 6755i

[esjones]

I have an Aastra 6755i that is showing "10 Errors" on the display right above the date and time. Looking at the Troubleshooting tab in the Admin interface, I see 10 entries in the error log, all with the description "Certificate Error." The phone is still working for both inbound and outbound calls, but I would like to diagnose and fix the error. Any ideas?

Thanks in advance.
