Fixed issues in V. 2.4 LTSR CU 1

  • With local app access enabled and the HDX RealTime Optimization Pack installed, when you log on to a VDA for Desktop OS and establish a video call between user1 and User2, the video content might not be displayed. Instead, only thumbnails are exchanged. [#LC8345]

  • The HDX RealTime Optimization Pack is installed and using Skype for Business User1 calls User2, and the call is initiated. The call disconnects when User2 accepts the call. The issue occurs when the conferencing configuration setting AudioClientPort in Skype for Business starts with an odd number, but the port range is configured to an even number. [#LC8764]

  • RealTime Connector is installed. When using applications that use a redirected webcam, such as Skype for Business, the webcam that is installed on a VDA for Desktop OS might be redirected and detected during an initial session launch. However, when you reconnect to the user session, the webcam is no longer detected. The issue occurs when RealTime Media Engine is not installed on the user device. [#LC8793]

  • The HDX RealTime Optimization Pack is installed and you dial in to a call from Skype for Business. After a period, you might not hear audio or you might hear distorted audio. [#LC9095]

  • The HDX RealTime Optimization Pack is installed and using Skype for Business the Instant Message (IM) notification might not be heard. [#LC9148]

  • When using Microsoft Office 365 or Skype for Business Online, calls might fail to establish intermittently. [#LC9236]

  • The HDX RealTime Optimization Pack is installed. User1 dials in to a call from Skype for Business that involves a Polycom RealConnect system. The Polycom system might not detect the video from User1. [#LC9332]

  • The HDX RealTime Media Engine might cause a delay in sending RTCP packets. This delay affects video performance. [#LC9338]

  • When a call is established between User1 from Skype for Business and User2 with Edifier conferencing server as back end, User2 might not be able to view the video from User1. [#LC9366]

  • When you establish a Skype for Business call, the call might fail. The issue occurs when lync.exe exits intermittently. [#LC9390]

  • When you dial in to a Polycom RealPresence Group 500 system using the HDX RealTime Optimization Pack installed as an endpoint, the video stream is not rendered at all or a lower frame rate is received. [#LC9453]

  • With the HDX RealTime Optimization Pack installed, the video stream is rendered at a lower frame rate when using Microsoft RTVideo codec. [#LC9458]

  • The HDX RealTime Optimization Pack is installed and optimized. If a call is established between User1 and User2, the microphone volume from user1 might be low within the call heard by User2. User1 can hear User2 correctly. [#LC9460]

  • The HDX RealTime Optimization Pack is installed. If a video call is established between User1 and User2 and escalated to a conference, the Skype for Business client might become unresponsive. [#LC9714]

Fixed issues in V. 2.4 LTSR

  • In some cases on Linux, the self-view picture might display only a corner portion of the full video. [#LOP-1814]

  • Maximizing the video window on low-end clients increases CPU usage, which might cause audio problems. [#LOP-2066]

  • AMD hardware acceleration endpoints might fail to send and receive video in a Meet Now with a Lync online Office 365 user. [#LOP-2306]

  • Simulcast does not support H.264 hardware encoding capabilities of UVC cameras. [#LOP-2320]

  • When an external Optimization Pack client starts a point-to-point call to an internal Optimization Pack client, the video quality on the internal client might be poor. [#LOP-2359]

  • When endpoints are using AMD chipsets and hardware accelerated decoding, users might see short periods of black incoming video and accelerated incoming video playback after resizing the conversation window. [#LOP-2360]

  • Audio might be distorted when CPU usage is high, especially in fallback mode. [#LOP-2368]

  • On team calls with Simultaneous Ringing set, a call disconnect might occur when someone else picks up the call. If you observe this issue, supply log files to Citrix Technical Support. [#LC6548]

  • With the HDX RealTime Optimization Pack installed, when a call is established between a Plantronics Calisto P240 handset phone and a Polycom CX300 desktop phone running on either 64-bit Red Hat Enterprise Linux 6.8 or 64-bit CentOS 6.9, the HDX RealTime Optimization Pack might pick up extra digits while dialing an extension. As a result, the wrong extension number is dialed. [#LC8346]

  • When a call is established, the audio quality might be poor in fallback mode. [#LC8461]
