Issue with Skype for Business macOS with IPv6

A while ago my, Skype for Business Client on my Mac was unable to connect while I was in the Office. So I switched to our Guest Wifi and did some check (because it’s always the Firewall, and the guest network is nearly open – That is an insider, sorry!) and it just worked fine.

After joining our regular network again, the Client stopped working, on WiFi and Ethernet. The Firewall logs didn’t show anything useful. The Skype Logs itself pointed me to the right direction: Connection issues!

So I started to dig deeper and checked all the hosts Skype for Business tries to reach from the command line (Curl is your best friend in such cases). Tools like Wireshark could do the same job.

Last year we announced plans for Microsoft Teams to become the primary client for Intelligent Communications in Office 365, replacing Skype for Business Online over time. Today, we are pleased to announce we have completed our roadmap for bringing Skype for Business Online features and functionality into Teams, and Teams is ready to meet your messaging, meeting and calling needs.

The Article sounds great, and Microsoft Teams is a very good solution! But a few things are (still) missing!

Enabling Skype for Business Client to use proxy server for SIP traffic instead of trying direct connection

This could causes noticeable delays when you sign in the client, especially if the client tries to connect to Skype for Business Online.

Microsoft published some Updates and a UC Lobby Blog article about that. There is also a Support article about that.

In the UC Lobby Blog article contains a the following:
