Known Issues and Limitations for WebEx Video Conferencing (WBS31)

WebEx Meeting Center Video Conferencing and CMR Hybrid Common Known Issues

This section contains known issues and limitations that affect WebEx Meeting Center Video Conferencing meetings (formerly known as CMR Cloud meetings) and CMR Hybrid meetings:

  
  •  

    Sending video from WebEx applications to video conferencing systems or applications  

      

    A WebEx Meeting Center video or CMR Hybrid meeting always starts at the best video resolution between video systems and the WebEx application. If high-definition video is available, it is available to all participants. If any participant on the WebEx side experiences poor network conditions, the resolution between video systems and the WebEx application downgrades to accommodate that participant. As a result, video resolution will also be poor for all other participants. The minimum bit rate a WebEx application must process from the WebEx Cloud to be able to receive both video and application or screen sharing (formerly called "desktop sharing") content is 1.2 Mbps. Less than that results in the WebEx application showing only the shared application or screen.

      

    For information about recommended bandwidth configuration settings for WebEx Meeting Center video conferencing meetings, see the Cisco WebEx Network Bandwidth White Paper.

      

    For information about recommended bandwidth configuration settings for CMR Hybrid meetings, see "Prerequisites" in the " Cisco WebEx Features and Important Notes" chapter and "Tips for Troubleshooting Low Bandwidth with the WebEx Meeting Center Client on Windows or Mac" in the "Troubleshooting" chapter of the CMR Hybrid Configuration Guide on the Cisco TelePresence Management Suite (TMS) Configuration Guides page. For additional information, refer to the Cisco WebEx Network Bandwidth White Paper.

      

  •  

    Presentation and data sharing quality 

      

    If you do not have adequate bandwidth, your presentation and data sharing in WebEx video and CMR Hybrid meetings can degrade to XGA (1024 x 768 resolution) and 5 frames per second (FPS). On TelePresence systems, users see a "letterbox" format.

      

    Assuming all WebEx clients have at least 2Mbps bandwidth, users in the meeting can enjoy 720p content sharing at up to 5 FPS.

      

    If WebEx clients have at least 3 Mbps bandwidth, the content share quality is 1080p at 3 FPS.

      

  •  

    In-meeting video experience  

      

    WebEx users can only see the active speaker or the most recently active speaker's video system in the WebEx application. Users on video systems who are not talking don't show up in the WebEx application.

      

    Users on video systems can only see the active speaker or the most recently active speaker from WebEx on their screens. WebEx users who are not talking don't show up on their screens.

      

  •  

    Full-screen video view 

      

    When presenters switch to full-screen video view while sharing their screen, application, or document, sharing is paused on the attendee side (the last-shared screen freezes). When the presenter exits full-screen video view, sharing automatically resumes.

      

    Attendees stay in full-screen video view when the presenter stops sharing and automatically exit full-screen video view when the presenter starts sharing again.

      

    If the Mac or PC WebEx application has two monitors, users can display a full-screen view on one monitor and full-screen or application sharing on the other monitor by dragging the video window to the other monitor and selecting the "View all participants in full-screen view" icon.

      

  •  

      Presenter may unintentionally disable video for all participants 

      

    If a WebEx user who is the presenter in the meeting unchecks the Video option in the Meeting Options dialog box, video is disabled for all meeting participants, whether they joined from a WebEx meeting application or from a video conferencing system. To restore video for all participants, the meeting host or current presenter should check the Video option in the Meeting Options dialog box.

      

  •  

    No Video in Downloaded MP4 Recordings

      

    Downloaded recordings in MP4 format which should contain both video of an active speaker and shared content do not show the video portion of the recording. The workaround for this is to play back the recording online.

      

  •  

    Other teleconference audio

      

    The audio connection option Other teleconference audio is not supported for CMR Hybrid and WebEx video conference meetings.

      

  •  

    Telephony service provider (TSP) audio accounts  

      

    For some telephony service provider (TSP) audio accounts, if a host with a TSP account schedules two adjacent CMR Hybrid or WebEx Meeting Center video conference meetings, with the second one scheduled to start immediately after the first one ends, and if the TelePresence scheduling system automatically extends the first meeting past the scheduled end, the second meeting will end automatically because the same TSP audio account and host access code cannot be used for both meetings at the same time.

      

    To work around this problem, hosts can set up two different TSP audio accounts with different host access codes, and use one account for the first meeting and the other account for the second meeting. Another option is for the administrator to turn off the option for the TelePresence system that automatically extends the meeting.

      

  •  

      WebEx meeting features 

      

    If you are hosting a meeting that includes video systems, the following in-meeting features are unavailable:

      

    •  

      Whiteboard

        

    •  

      Document sharing

        

    •  

      Polling

        

    •  

      File Transfer

        

    •  

      Chat (with TelePresence room participants)

WebEx Meeting Center Video Conferencing Known Issues

 
  •  

    Call My Video System

      

    The option to Call My Video System may fail if attendees are required to press '1' and no RMS or Traversal Licenses are installed on the Customer Expressway-C and Expressway-E pair.

      

  •  

      Display names 

      

    Display names for video  conferencing system users are not visible in the WebEx meeting video window.  This issue will be addressed in a future release.

      

  •  

    Leaving and reentering a Personal Room 

      

    Sometimes, when hosts end a WebEx Meeting Center video conferencing meeting by leaving their Personal Room and then reentering their Personal Room within a few seconds, they may hear an audio prompt about an invalid meeting. If this happens, the host should hang up and wait a few seconds before redialing the Personal Room.

      

  •  

    12-hour limit 

      

    A scheduled WebEx Meeting Center video conferencing meeting cannot last for more than 12 hours. Hosts and participants can reenter the meeting, or can schedule a new one.

      

  •  

    Telephony service provider (TSP) audio 

      

    Users on video systems will not be able to join meetings on WebEx sites that utilize TSP audio conference bridges until the meeting host has configured the toll phone number for their provider. To avoid this problem in a meeting, we recommend that hosts specify the toll number of the TSP audio service in their account preferences.

      

    Due to some dial-out sequences having multiple steps and longer prompt durations that cannot be interrupted, it may take a while before audio from WebEx users joining via telephones can be heard by video systems and video systems can be heard by telephones. During this time, users who have joined from video systems have no indication that their audio is not being heard by users who have joined using WebEx. To avoid this problem, all participants should wait until the TSP audio dial-out sequence is complete, which is indicated by telephone handset icons appearing next to participants' names in the participants list.

      

  •  

    Network problems 

      

    Due to network impairments on a user's video system, the display names of participants may appear truncated in the video endpoint active presence view.

      

  •  

    Video systems joining without encryption 

      

    If attendees join a meeting using video systems that do not setup encrypted signaling links or use encrypted media links, the meeting cannot be considered fully secured, since there are other devices whose connections cannot be secured.

      

  •  

    Call leg security

      

    The encrypted meeting status icon on video systems utilizing Telepresence Interoperability Protocol (TIP) or Call-Info security attributes does not reliably indicate the encryption status in meetings. Even when all call legs are encrypted, this icon may still indicate an unencrypted meeting.

      

  •  

    Support for Microsoft Lync or Microsoft Skype for Business Applications

      

    •  

      Content that is shared in a WebEx Meeting Center video conferencing meeting is transcoded into the main video channel for users on Lync and Skype for Business clients

        

    •  

      Clients using RTV video codec is not supported, including Lync 2011 on Mac OS.

        

    •  

      To ensure 2-way video in a meeting users must select Video and then select Start Video on the application before joining the meeting.

        

    •  

      After joining the  meeting, users may need to select Start Video one more time.

        

      
  

Known Issues for Using WebEx Meeting Center Video Conferencing with Spark

  
  •  

    Spark and Mozilla Firefox

      

    When Spark users in Mozilla Firefox share their screen, WebEx users see a black screen, instead of the shared content. When WebEx users share their screen, Spark users in Firefox can see the shared content.

      

  •  

    Video Call-Back to Cisco IP Phone 8800 Series Video Phones Registered to the Spark Calling Service

      

    When you initiate a video call-back from the meeting to Cisco IP Phone 8800 Series Video Phones registered to the Spark Calling service, where the site is configured to require DTMF key 1 to connect to the meeting, this connection fails. The workaround for these devices is to disable the requirement to enter DTMF key 1 to connect to meetings.

      

 

CMR Hybrid Integration Known Issues

The following issues apply to joint meetings with WebEx and TelePresence in the CMR Hybrid solution:

  
  •  

    Participant list 

      

    •  

      The WebEx host in a joint CMR Hybrid meeting with WebEx and TelePresence is not able to see a complete list of all WebEx and TelePresence participants.

        

    •  

      TelePresence participants are listed as "TelePresence Systems" in the WebEx Participants list of a CMR Hybrid meeting.

        

      
  •    

    Exceptions to a recurring meeting series using WebEx Productivity Tools  

      

    Although recurring meeting exceptions for CMR Hybrid meetings are now supported in WebEx Productivity Tools. "Orphan" meetings are not yet supported. For example, you cannot add a WebEx meeting and TelePresence rooms to a single occurrence of an Outlook-only meeting series. If you want to make these features available for a single occurrence, make the whole series a WebEx and TelePresence meeting.

      

    Edits to a meeting series with exceptions that were changed before version WBS30 follow Microsoft Outlook's rules, where possible, regarding treatment of the exceptions' properties.

      

    If a host edits the subject or changes the meeting time of a single occurrence of a recurring CMR Hybrid meeting series by editing it directly in the Microsoft Outlook calendar, and then removes WebEx from the entire series, the WebEx meeting information still appears in the exception meeting.

      

    If the host scheduled a recurring CMR Hybrid meeting series, and the date of the first occurrence has passed without that meeting being started, the host cannot update the date of that individual occurrence. However, the host can change the date for the entire meeting series.

      

    If you remove the WebEx meeting from an individual occurrence of a CMR Hybrid meeting series, you change it to a TelePresence-only meeting. However, the Cisco TelePresence Management Suite (Cisco TMS) still shows WebEx information for that exception meeting.

      

    If you change all the individual meeting occurrences within a meeting series into exceptions, and you then attempt to add a TelePresence meeting to the entire series, Cisco TelePresence Management Suite for Microsoft Exchange (Cisco TMSXE) assumes the series in the past and does not give adequate warning messages to the meeting scheduler or host. Users can work around this issue by deleting the current series and creating a new series that has TelePresence added, and then editing the exceptions to that series individually, as exceptions, or deleting all the exceptions and creating individual meetings.

      

  •    

    Exceptions to a recurring meeting series using WebEx Productivity Tools  

      

    Although exceptions to a recurring meeting series are supported for WebEx-only meetings on CMR Hybrid sites in WBS29.11, exceptions to recurring series are not supported in WBS29.11 for CMR Hybrid meetings. Creating an exception meeting in a meeting series either using Cisco TelePresence Management Suite (TMS)-based scheduling methods (Cisco TelePresence Management Suite Administrator, Cisco Smart Scheduler, and so on.), or using mobile calendars synced to Microsoft Exchange that connect to TMS may result in meetings where the WebEx portion of the meeting cannot be joined through WebEx applications if the exception falls beyond the last regular meeting occurrence in the meeting series.

      

    The following issues exist for exceptions to a recurring meeting series using CMR Hybrid meetings and Productivity Tools:

      

    •  

      Exceptions to a recurring meeting series for CMR Hybrid meetings are still NOT supported as of WBS29.13, and users are warned accordingly (for example, unsupported editing options are disabled, and error messages are included in email invitations) when they attempt to schedule them using Productivity Tools.

        

    •  

      WebEx meeting applications and TelePresence devices can join the same CMR Hybrid meeting, even if a normal exception to a meeting series has been created. WebEx does not support creating orphan meeting exceptions, such as adding WebEx to a single occurrence of a meeting series.

        

    •  

      Hosts can still edit the following items for a CMR meeting series that does not have exceptions: WebEx special properties, such as alternate hosts, audio options, and the WebEx meeting password; Microsoft Outlook common properties, such as subject and attendees; and TelePresence properties.

        

    •  

      Once an exception has been made to a CMR Hybrid recurring meeting series, the following conditions exist:

        

      •  

        The Outlook common properties can still be edited for both the exception and the meeting series.

          

      •  

        The TelePresence properties cannot be edited for either the exception or the meeting series (the panel for editing TelePresence settings is disabled).

          

      •  

        The WebEx special properties cannot be edited for either the exception or the meeting series.

          

        
    •  

      If a WebEx-only meeting series has exceptions, TelePresence cannot be added to it.

        

    •  

      Unlike prior releases, in WBS 29.11.3 and later, the following features are not available for CMR Hybrid users:

        

      •  

        CMR Hybrid users cannot edit the TelePresence properties or WebEx special properties in a CMR Hybrid series that has exceptions.

          

      •  

        CMR Hybrid users cannot add or remove TelePresence or WebEx entirely from a series if it has exceptions.

          

        
    •  

      The Mac version of Productivity Tools, which is new in WBS29.13, is expected to have similar limitations for exceptions to a meeting series.

        

      
  •  

    Making someone presenter 

      

    A TelePresence system becomes the presenter when a VGA cable is connected to the laptop. In a standard WebEx meeting, a user has to ask the host to make him or her the presenter. By default, the ability for anyone in the meeting to "grab the ball" or request to be the presenter is enabled for CMR Hybrid users. Starting in WBS29.11, the Anyone Can Share feature allows anyone to share without requesting to be the presenter. This option is also enabled by default for CMR Hybrid users. If you are connected to both Cisco Jabber and WebEx on the same computer and try to share content from Jabber, you get repeating share windows. We recommend that you always share from WebEx if you have both Jabber and WebEx on your computer.

      

  •  

    Time zone 

      

    The time zone for the WebEx site must match the time zone for the Cisco TelePresence Management Suite; otherwise the meeting time is not synchronized.

      

  •  

    Leaving a meeting 

      

    Unlike WebEx-only meetings, which have an option to automatically extend if attended by audio-only callers, when all TelePresence endpoints leave a CMR Hybrid meeting, if there are no users of WebEx applications to pass the host role to (or if audio-only endpoints are the only other attendees of a CMR Hybrid meeting), and capacity constraints on the TelePresence Management Suite do not allow the TelePresence side of the meeting to automatically extend beyond the scheduled end time of the meeting, the meeting ends.

      

  •  

    File sharing and whiteboard sharing 

      

    File sharing and whiteboard sharing are not supported in CMR Hybrid meetings. We recommend that you use screen sharing or application sharing instead.

      

  •  

    Audio codec 

      

    Cisco recommends the G.722 audio codec on the CMR Hybrid link for the best user experience. The G.711 codec is also supported as an alternative. We do not recommend or support use of the G.729 codec on the CMR Hybrid link.
