General fixed issues

  • When a RealTime Optimization Pack user is participating in a conference as an attendee, and the conference organizer initially disables and then re-enables attendee video, the Skype for Business UI (the video icon) does not correctly reflect the current state of sending video to the conference. When attendee video is enabled, the participant's video is sent to the conference, but the video icon is still crossed-out, indicating disabled video.

    [#612875]

  • When the H.264 video codecs are used and media encryption is enabled, you might see these issues:
    • On Windows and Mac OS X, camera capture stays on even if the video call stops video transmission, is put on hold, or is converted to audio.

    • On Linux, camera capture stays on even if the video call stops video transmission, is put on hold, or is converted to audio. In addition, the first call to use the camera keeps exclusive use of the camera unit the call is terminated. If a second call is accepted, it cannot transmit video until the user hangs up the first call.

  • When you start a call with a hardware-based Acoustic Echo Cancellation (AEC) device (for example, a Plantronics headset) and then switch to a device without hardware-based AEC (for example, a Polycom phone), the far-end device might experience echo.
