Yes although the Jabber for Everyone promotion is also available in the 8.6 release as well. Essentially the server software is given away as long as the customer purchases the minimum 50 UCL/UWL users for CUCM and covers CUCM with ESW/UCSS. Everyone in the organization is entitled to IM&P functionality but any softphone/video functionality still requires a license. Example: your company has 100 employees but you buy 50 UCL/UWL licenses. 50 people can have softphone but everyone can chat.
