Here is a screenshot of what you should have in general:
HTTPS is what Lync uses remotely. SIPS or TCP 5061 is what lync uses internally. The ACL above signals to the firewall to inspect all of this traffic and then classify the traffic as voice if we see voice traffic. Typically you would restrict that source and destination of the TCP 443 and TCP 5061 traffic so that the controller does not attempt to classify ALL TCP 443 traffic.
You should then start a call and the type "show datpath session table <ip address of client> | include V" to see if it is being classified as voice:
(Aruba7005-US) #show datapath session table 192.168.1.237 | include V
C - client, M - mirror, V - VOIP
22.240.16.25 192.168.1.237 17 52679 50053 0/0 0 46 0 tunnel 14 1a0 273 102960 FHTV
22.240.16.25 192.168.1.237 17 52186 50052 0/0 6 0 0 vlan 1 192 19647 1580474 FHPTIQV
192.168.1.237 22.240.16.25 17 50053 52679 0/0 0 46 1 tunnel 14 1a0 618 406485 FHTCV
192.168.1.237 22.240.16.25 17 50052 52186 0/0 6 0 0 vlan 1 192 11319 2372524 FHPTCIQV
In the example, my off-premise Skype for Business Server is 22.240.16.25 and my Lync/S4B client is 192.168.1.237
Once the call is started, the call continues with high ports and using "Classify Media" in the ACL determines what ports those are and sets the "V" flag.
"show ucc client-info" would show my client that is recognized and more info.
(Aruba7640-US) #show ucc client-info

I hope all of that makes sense...
