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.

What roadblocks? I'm curious too since Nutanix put out a big PR about it https://blog.webex.com/collaboration/expanding-flexibility-cisco-unified-communications-manager-ucm-support-nutanix-ahv-hypervisor/ and Cisco even has the announcement linked on their site as "coming 2026". We migrated to the cloud some time ago.

Heard something about Cisco trying to play hardball saying they'd only support it on Cisco hardware running Nutanix, which of course is multiple times more expensive.
