Hi Som,
Please continue setup the Cisco system, the activating password I set may expired, so you can go ahead setup by yourself.
You never answer me how many devices you have? Since if fully setup you need to have 9 devices. 3 on each server. But please let me know if not let’s work on Lync and Cisco first.
Also I list the required OS for each server, for 10.3.1 the 10.3.1.104 seems working so please give it a try.
If you have extra time, so an exploratory for the features on Cisco, play around with Jabber client.
For Lync system, the DT client is Lync.
