Audio problems in Skype for Business while connected to TTUnet VPN


Connectivity and audio performance problems occur in Skype for Business while connected to TTUnet VPN.




The official recommendation is not to use VPN while conducting Skype for Business calls.


Workaround #1

If you have a computer that still resides on campus, we recommend you use Skype for Business on your home computer, and then remote into the computer on campus to access any TTU related resources that cannot work off-network.

Workaround #2

Only connect via VPN for necessary functions and then disconnect.

Workaround #3

If a laptop or desktop needs to be connected to VPN consistently, the Skype for Business mobile app (Android, iOS, or iPadOS) can be used instead. Calls for response groups will ring Skype for Business mobile as long as you are signed in to the response group. We recommend disconnecting Skype for Business on your computer if you are using the mobile app.

Workaround #4

If you do not need to receive response group calls, you can configure Skype for Business to forward personal calls to a mobile or home number—just be aware that voicemail is then handled by those systems.

Workaround #5

If you are mainly using these tools to communicate with TTU individuals internally, we have other voice and conferencing options that are available such as Microsoft Teams and Zoom.

Workaround #6

If you only experience issues when you connect or disconnect VPN, we recommend connecting your VPN client first, then connecting Skype for Business. Then, when you are done with both tools, disconnect Skype for Business then disconnect VPN.

Workaround #7

Configure SfB meetings to prompt for an audio device when joining meetings for the flexibility of using SfB when VPN is disconnected versus having it call a mobile number when VPN is connected.
