I would start by installing an scenario that is supported and tested to work, CUCM 8.5 cannot be installed on anything beyond ESXi 5.1. It might be related to your issue.

Thanks for reply,

But why in Publisher Server (installed in Esxi 5.5 !!!!) , NTP is so crazy :((

i will try its in VMWareWorkstation and show you the result ...

FYI, we don't support VMWareWorkstation either

sometime it takes a time for publisher to reflect ntp status, wait for publisher to show ntp is accessible and then try to install.

Hi

you need to configure the NTP server with stratum-1, so best option is to point it out to any of the Router or switch IP ans NTP server.

check and update the status.
