Skype for Business: How to setup QoS at client side?

Well there are 2 ways you could perform this is by editing the client’s computer (local group policy) or push the settings using group policy management.

Anyway, both of these methods or steps are similar and simple to setup.

*Note: A wrong value can causes the QoS not running correct

Steps for local group policy;

1. Make sure you are login as local administrator on your computer
2. Go to > Start > Search > Group policy
3. At the group policy > computer configuration > Windows settings > policy QoS settings
4. Create new policy
5. Just follow the below image to create total of 5 QoS policies

6. During creating the policy, just change which is necessary. Leave the others as default.

7. Do a restart of the computer (I always do this)

Steps for  GPM;

1. Open GPM
2. Create a new GPO and name it
3. Right click the GPO and click edit
4. At the group policy > computer configuration > Windows settings > policy QoS settings
5. Create new policy
6. Just follow the below image to create total of 5 QoS policies

7. Link this GPO to the OU you wish to have this GPO implemented

8. After that remember to do gpupdate /force on both the server and the client computer

For testing;
1. Install wireshark

2. Select the network you connected and Start the wireshark (Start Capture traffic)

3. Start your skype for business audio call or video call, or both within the same network. Do a peer-to-peer communication.

4. Talk to the audio or make some sound for a minute or 2.

5. End the skype for business call (audio or video)

6. Stop your wireshark

7. Save your traffic

8. You should be able to see your QoS is working
