[cisco-voip] NTP sync problem

[Robin Clayton]

" I don't think UCM will sync with a stratum 8 or higher clock."

I had failures in my test environment until I set the stratum lower on my dummy NTP server which has no reference server.

Any chance the internal ntp server lost sync with its sync source?  If so, the internal server may have fallen back to the internal clock and its stratum level changed.  I don't think UCM will sync with a stratum 8 or higher clock.

Our cucm cluster suddenly stopped syncing with our internal NTP servers recently for no apparent reason.

Our version is: 8.6.2.22900-9

I have been informed no work was carried out on the servers running the NTP service. Has anyone else come across a similar issue?
