With the requirement to demonstrate a Skype for Business audio integration with a CUCM, it was decided to integrate within my system.

I currently have some UC 10.x and 11.x licensing that is purchased and used for demonstrations. With the recent purchase of the 11.x licenses, a Prime License Manager (PLM) server was stood up to manage the multiple clusters using multiple versions of the CUCM platform. This post walks through the process of standing up a stand-alone PLM server, pulling licenses from the Cisco licensing website, and the rehosting of licenses from a legacy license manager.
Looking to increase the switching capabilities within my setup to support the Gigabit needs of my ever growing environment, I ran across a spare 4507E chassis and some line cards. With the new platform came the opportunity to research and apply the latest QoS configurations available.
