In order to get full visibility and control of this UDP traffic customer can use the Zscaler Adv. port ranges and a Quality of Service policy for your clients on Skype for Business Server.

Good news, the Skype for Business Mac client is now generally available It’s been a long time waiting, but Microsoft has hit their October 2016 deadline. Therefore the recommendation for Zscaler customers using Teams / S4B is be to ensure that a) clients can DNS resolve internet addresses for Teams / S4B and b) there is a suitable path for Teams UDP ports to get out to MS.
This is called out in MS blog here:Įven if an explicit proxy (PAC file/ZApp) is set on a client the Teams / Skype for Business (S4B) will first attempt to connect via the more optimal UDP ports, and if those are unreachable it will look for less optimal methods such as explicit proxy via TCP.įortunately with Zscaler Internet Access you are able to combine explicit and transparent traffic forwarding methods.
You’re correct to say that the use of explicit proxy (PAC file) will mean that the traffic will use TCP which is sub-optimal for Teams traffic.
