Skype for Business – WSS – Firewall etc!

I need a solution


We have recently implemented the WSS and are struggling to get Skype for Business to work.

I’ve tried using a PAC file connection method, and specifying the data centre IP address in the browsers proxy settings – both dont work. 

In my PAC file, and my proxy exceptions i’ve listed a whole list of locations to bypass, i’ve also excluded Office365 from SSL scanning.

On my firewall we also have a rule that allows people to access Skype for Business locations. 

Regardless of the above, when using the WSS users cannot connec to Skype for Business.

I assume i’m doing something wrong, but i’m not sure what.

Any help on how other people have got this working would be great.
