I have have had various discussions with our systems teams over the years and am experiencing periodic ntp alarms from CUCM, UCXN, & UCCX - 3 separate regions/clusters with 1 NTP source. I know windows server NTP is not a supported so I am trying to make a plan to migrate away from that.
If I setup our Cisco cores (Nexus 9ks) to use pool.ntp.org as their NTP source and then set the 9ks as the source for the UC clusters, would that be supported and sufficient? Is anyone doing something similar? I haven't been able to convince the systems team we need an NTP appliance.
Any advice is appreciated.

I do the same, I always sync my Cisco core switch with time.google.com or local NTP server. Then Make the core as ntp for UC applications.
I always make my core
ntp master 2

Yes that would work. As we actually do have NTP appliances we do not ourself use this in our production system landscape, but we have used Cisco hardware as an NTP server for various test and lab systems in the past and it worked great.
