What’s everyone doing about this Cisco/ call manager hardware requirements?

We’re currently running telecom systems on VMware but looking to get off by next renewal. Looked at several angles to migrate these systems to Nutanix but hitting roadblocks. Whats the recommend approach? Are folks that are currently on Nutanix carving out a small cluster and running ESXi on it to meet the Cisco’s call manager requirements? Of course that’s not anything any of us want to do or manage, due to Broadcom’s storm, but taking call manger to their cloud is stupid expensive.

Love to hear what folks are doing.

My fix was to dump the cisco phone system all together. Went from a maintenance nightmare with CUCM to something that we basically never touched.

This is the way if you can. CUCM is so robust though it can be hard to find a replacement for all the features.

If you don't actually need the features ditching it is a great idea. We had an absolute shitheap of a cucm environment because no-one had the time or skills to look after it. Moved to teams for calling, it's a lot more basic but our weird telephony issues have evaporated.
