I'm currently looking into how I can lab CUCM. Seems like getting one up myself is time consuming, at least from my understanding. I thought I had read there were labs through the Sandboxes, but I am not seeing CUCM at all, or maybe they've retired them. I see a lot of out-of-date information, like 2023 seems to be the earliest I can find anything. Is there any way to lab this in a preloaded environment, or is building up one at home my best option right now?
