https://community.cisco.com/t5/devnet-sandbox/looking-for-a-cucm-lab/m-p/5543458#M12318 <P>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 I see a lot of out-of-date information, like 2023 seems to be the earliest I can find anything.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?</P> Mon, 06 Apr 2026 18:12:56 GMT Mathieuda 2026-04-06T18:12:56Z https://community.cisco.com/t5/devnet-sandbox/looking-for-a-cucm-lab/m-p/5543458#M12318 <P>I'm currently looking into how I can lab CUCM.

From what I heard from the sandbox team, there are no plans to bring it back as of now. I believe there are some instances on dcloud.cisco.com but only for customers, which are added by their Cisco account team</P> <P>If you find stale docs pointing to this sandbox please share them so we can remove the references.</P> Thu, 09 Apr 2026 09:53:58 GMT https://community.cisco.com/t5/devnet-sandbox/looking-for-a-cucm-lab/m-p/5544305#M12334 Jesus Illescas 2026-04-09T09:53:58Z
