Fixed issues

Fixed issues in V. 2.4 LTSR CU 2

  • When you dial in to a Pexip Infinity conferencing device using the HDX RealTime Optimization Pack that is installed on the endpoint, attempts to establish a video or an audio call might fail. [LC9037]

  • When a user initiates a call with the consumer version of Skype to another user, who is using Skype for Business and has the HDX RealTime Optimization Pack installed, the call might fail. [LC9567]

  • When you use Microsoft Skype for Business from a published desktop and you add a third participant to the conference call, your status turns to Hold. [LC9606]

  • With the HDX RealTime Optimization Pack installed, if a video call is established between User1 and User2 using the Cisco Meeting Server (CMS), the video might become distorted. [LC9744]

  • When Skype for Business is started and is optimized, the NumLock status on the USB ten keyboard that is connected to the user device might be considered OFF. [LC9786]

  • When many processes are running on the VDA, the Skype for Business user interface within the session might become unresponsive. [LC9845]

  • With this fix, the version number of the RealTime Media Engine is added to the session description protocol’s User-Agent attribute. [LC9885]

  • When the default device on the endpoint and that of Skype for Business are different, the audio volume might drop to zero. [LC9887]

  • When you establish a Microsoft Skype for Business call to a Cisco Meeting Room appliance, the video might not work. [LC9945]

  • When you are using a wireless or Bluetooth headset, the audio link to the wireless headset stays open causing the headset battery to drain much faster. [LD0331]

  • When a video call is established between two users, the RealTime Media Engine that is installed on the caller side might ignore the Common Access Card (CAC) policies and send the video stream at a high bitrate without any restrictions. [LD0364]

  • The disabling feature might fail to work and the logging continue after you disable the RealTime Connector logging using the following registry key as described in Configure features.

    • HKEY_CURRENT_USER\Software\Citrix\HDXRTConnector, Name: DisableFileLogging, Value: DWORD, Data: 0 or no value - logging enabled, 1 - logging disabled [LD0045]

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]
