- Check the Skype for Business Admin Center to see whether audio/video capabilities are turned off for the whole domain or for the user or users who are experiencing the issue.
- Try using a different audio/video device on the same computer and try using the same audio/video device on a different computer. If the issue can be narrowed down to the specific audio/video device, verify that the USB Peripheral device is certified for use with Skype for Business Online.
- Run Windows/Microsoft Update and install any updates (optional or required) for your audio/video devices.
- Open the Control Panel and bring up the Device Manager. Look under Sound, video and game controllers for any devices that have conflicts.
- Verify network connections for the best experience. To do this, follow these steps:
- Verify that you're connected by a direct wired connection, by a virtual private network (VPN) connection, by a Wi-Fi connection, or by a direct Internet home office connection.
- Determine whether one or both users are roaming from one wireless access point to another wireless access point. In this situation, a delayed presence scenario may occur. In this scenario, the user may appear online but may actually be between two wireless access points.
- Try to reproduce the issue when both users are on a wired connection, on a VPN connection, or on a Wi-Fi connection.
- Reset the Windows Sockets (Winsock) Catalog. To do this, follow these steps:
Note You must be logged on to the computer as an administrator to do the steps.

- At the command prompt, type the following command, and then press Enter:
netsh winsock reset
- Restart the computer.
- Reproduce the issue by using one contact or multiple contacts. To do this, follow these steps:
- If the issue is reproducible with only one contact, determine whether anyone else can reproduce the issue with the same contact.
- If the issue occurs with multiple contacts, check for commonalities among the group of contacts.
