Skype with Zscaler


(Rajeev Srikant) #1

Would like to know the standard practice for using Skype for business with ZScaler.
Does Zscaler supports SFB ?
If we use Zscaler as proxy service & if we use Skype under Zsclaer proxy will it work ?
Or it is recommended to bypass Zscaler for Skype traffic ?

Hi Rajeev,
Zscaler fully supports O365 and we have a close working relationship with microsoft to ensure we handle their application in the best way, this includes supporting SfB / Teams. We have extensive documentation on how best to configure Zscaler and O365 to work together, see here for the root of the O365 document repository -->

Many thanks,

But I would like to clarify is it recommended to send Skype traffic to Zscaler.
Since it is voice traffic, should it go through Zscaler ?
What is the advantage of sending Skype traffic to Zscaler ?

We can prioritise and optimise 365/Skype (via great peering channels, as well as our wire speed TCP stack) the Skype channel as we’re inline, we are also able to provide visibility into utilisation when contrasting against other SaaS App and the general Internet traffic. Also, it’s a much simpler forwarding topology when sending all traffic via Zscaler, steering specific apps to go direct can create a complex routing environment and much overhead to maintain.
