Skype for Business – QoS with 3rd Party Applications

Are you using Citrix or any other 3rd party application that handles media (e.g. Call Recording / Contact Centre) with Skype for Business?  You may find you’re not marking this traffic with the correct DSCP markings.

Skype for Business – Director Pool in DMZ (Secure Environment)

I was recently working for a customer where their security policy prohibited traffic from the internet terminating on servers within the LAN. Skype for Business (Including previous versions Lync and OCS) uses a Reverse Proxy to terminate web requests within the DMZ and re-write the requests to the Front End Pool(s) within the LAN.  The request is received on TCP/443 (HTTPS) and sent to the Front End VIP on TCP/4443.  In the case of...
