Hello,
Our IT team has started to roll out Skype for Business in our enterprise and I am trying to optimize the Aruba Wi-Fi and get UCC visbility info from the Skype calls. We use Office 365, which, according to the Lync VRD, means we are limited to using the hueristics method ("classify-media" in the ACL).
I have 2 questions.
First question: What do I use as the front end server in my ACL rules?
According to our setup instructions for OS X users, we configure Lync to connect to sipdir.online.lync.com, but I'm not certain this is what I should use as the front end server. Furthermore, different DNS servers seem to report several different IP addresses, but any DNS server I try seems to only respond with a single entry. I found this list from VirusTotal.com:
host 131.253.161.203
host 132.245.209.28
host 132.245.209.21
host 132.245.193.35
host 132.245.193.21
host 134.170.54.26
host 134.170.54.15
host 132.245.113.21
host 132.245.113.25
host 132.245.1.25
Are these the servers that I need to be using for my front end servers netdestination, or should I be adding something else?
Second Question: Do I need to open UDP ports 1025-65535 in the ACL if I'm using the heuristics method in AOS 6.4?
Any insight on how to set this up would be appreciated.
