I'm trying to update the version of CUCM 188.8.131.520-3 to 184.108.40.2060-4.
Go to Cisco Unified Operating System Administration -> Settings -> Version try to switch version from Active Version (220.127.116.110-3) to Inactive Version (18.104.22.1680-4), after clicking the server version of the Switch goes to reboot.
After you restart the active version does not change. Remains 22.214.171.1240-3.
In what could be the problem?
