UCM 15 Collaboration Sandboxes

[mborgert1]

To test software integrations with CUCM and UCCX systems, I have utilized DevNet sandboxes for various tests and allow our internal admins get familiar with UCM systems.

It was recently noticed that UCM sandbox environments are no longer available.

Was there a formal announcement for this?

I found this community discussion that references UCM 14 sandboxes being removed for security purposes, but does that mean that UCM 15 sandboxes still may be made available?

Does Cisco have recommended cloud-based alternatives that have replaced the UCM and Collaboration sandboxes?

Thanks in advance for any assistance or clarifications.

The UCM sandboxes were removed as the other comment shared due to security concerns. The sandbox team shared that on the comment of another post some months ago (I can't find it right now).

I checked and on dcloud.cisco.com there other instances of UCM however I don't know this tech very well to know how useful they are. To gain access to dcloud.cisco.com you need your Cisco account team or partner to help you to gain access.
