When you join a Microsoft Lync Online conference by using the Microsoft Lync client, you can't see or connect to the video feed. This issue occurs if you use the call me option when you connect to the conference.
To work around this issue, don't use the call me option when you join a conference in Lync. Instead, use a phone to dial in to the audio conference. Then, you can add video by using Lync.
The call me option phones you when the conference occurs by using an audio connection that's set up by the Audio Conferencing Provider (ACP) Multipoint Conferencing Unit (MCU). To connect by using video, the Audio/Video (AV) MCU must link the audio and video connections. However, the audio connection is already used by the ACP MCU, and the client can only create a single audio connection.
