Fixes: - Audio: After a video call was made from the RealPresence Group system, all future audio-only calls placed to a SoundStation IP 7000 phone had audio output from the RealPresence Group system speakers and the SoundStation IP 7000 speaker. This issue has been corrected. - Interoperability: When you used a RealPresence Group Series system to join a multipoint call while you were muted, the Microsoft Lync 2013 client displayed no video. Similarly, if you muted and unmuted a RealPresence Group system during a multipoint call, the Lync 2013 client displayed no video. This issue has been corrected SharewareABC suggest you to use the most recent driver version. Before install this driver we recommend to set a restore point. This way you can reverse system if the driver is wrong.
