Hello, I don't believe that's the case. According to Cisco, you register the phones directly to Spark. Check out http://www.cisco.com/c/en/us/solutions/collateral/unified-communications/hosted-collaboration-solution-hcs/datasheet-c78-736823.html#_Toc444123188 .
This could eliminate the need for a UCM at all as well as voice gateways if I understand it correctly.
