I want to use Skype for Business Client under Proxy. In my environment i have proxy & I want my Skype for Business client to use that proxy to connect to the internet where the Skype for Business server is published.
Would like to know what ports will be used by Skype. By default Proxy & the internet firewall is opened for only 80 & 443.
Would like to know will this be sufficient or any additional ports will be required on Proxy & firewall for skype for business client to work.

Office 365 Skype for Business Online Edge Servers listen on the whole range of TCP and UDP ports 50000 - 59999 for Lync client audio, video, and Desktop Sharing sessions. Network traces will show client source ports in the 50000 - 50059 range connecting to destination ports on the Skype for Business Online Edge Servers in the 50000 - 59999 range.
