This issue occurs in one of the following scenarios:
- A computer that is running a Microsoft Skype for Business client in Windows accesses network by using a wireless network adapter or a point to point protocol (PPP) adapter.
- The connection-specific DNS suffix of a wireless network adapter exceeds 31 characters.
- Driver defined description of the wireless network adapter exceeds 63 characters.
Note The audio/video session may be an audio/video call or conference.
This issue occurs because Skype for Business enumerates the wireless connection’s information before it starts a media session.
