I have an issue about a Cisco Unified CallManager 188.8.131.520-11. When updating any information of a device (a phone 7911) and then clicking in "Save" I receive a message box with the following text: "Operation Completes By Date/time must be greater than current date/time".
The same occurs when updating others parameters of many devices (phones, in general).
If any person is already faced this problem, please, help me in solve it.
there are many bugs for that error:
Internally found cosmetic defect: Duplicate
An error message is having a small problem.
Internally found moderate defect: Verified (V)
Some characters deleted in Phone Configuration page messages.
Internally found severe defect: Unreproducible
Updating a phone config shows error
I had the same problem and I resolved by changing the Certification Authority Proxy Function (CAPF) Information in the phone configuration page, by selecting No pending Operation instate of Install/Upgrade
Thank you. For me, changing "Certification Authority Proxy Function (CAPF) Information -> Certificate Operation" from "Delete" to "No Pending Operation" fixed this issue for me. Again, thanks!
