I have seen random issues with the NTP stratum and sync between different versions of CUCM. What stratum is your NTP server set to? You could try to adjust it to (the stratums go from high to low with lower being better, so you can start at 9 and go down from there to see if there is a difference. CUCM needs 9 or greater - in other words 1 - 9) and reset the NTP service to see if you can get in sync. Also verify that the CLI output is correct by pinging the NTP server directly from the CLI of CUCM.
I for one question whether "accessible" is saying "I can confirm the host is alive on the network" or if it actually means "I have talked to this host on port 123 and it responded in a positive fashion".
In either case, you seeing the server as "accessible" doesn't mean the CUCM is synchronized (as you already know). Have you checked 192.168.32.43 to see if it is synchronized correctly to 192.168.32.41 (the reference clock for .43)? Are you able to configure another host (like a cisco router or switch) to recover clock form 192.168.32.43? If so, does the test host show a ntp status of synchronized?
Also, what is 192.168.32.43? Is it a router? A hardware clock? Linux host? Windows host?
Finally, do you know if the CUCM publisher was ever able to synchronize clocks with .43?

The short answer is that you don't.... That isn't entirely true while at
the same time it kind of is, but for the most part you don't configure
the softkeys. You enable or disable them via TCL. Here is the long
