So you want to know how to bypass Cisco's entire licensing program? I doubt you will get an explanation of how to do that.
UCM is designed to give you sufficient licenses in demo mode to perform lab-type use out of the box. If you perform an installation and do not upload a single license file, you will get a small pool of node licenses and DLUs.
If you are doing a DRS restore to test this, you will need to delete the license files from the CLI and restart the machine. There is a bug surrounding FlexLM properly modifying Informix when deleting license files so you may have mixed results with returning to demo mode.
