MCU open caveats are included in the following categories:

General

Interoperability

Web/Control

Encryption

H.239 Dual Video

General

Dual protocols (SIP and H.323) can be simultaneously used on hardware versions ending in B06 or later. The hardware version number is displayed in the Hardware version field of the Basics tab in the MCU Board interface.

The EMP (E) card cannot occupy a system slot in the chassis.

Not all the participants are displayed when using auto-switch in a CP cascaded conference and then switching to a full screen display.

When cascading two conferences with auto-switching enabled in the service definition, you must manually start auto-switching from the Conference Control web interface.

When changing the user name or password used to log in to the system, it is impossible to perform chairman operations in the conference control until logging out and logging in again with the new user information.

When changing the MCU security mode from High or Maximum to Standard, an MCU restart is required to be able to connect to the MCU using Telnet.

Dynamic layout does not work for a child view when Preserve Local View is applied to the child view.

If video output is set to more than 1000 Kbps, video input can be limited for some specific layouts. For more information contact your local Cisco Customer Support representative.

If you use a layout with 10 or more sub-frames with video output of 704 Kbps or higher, video input is limited to 320 Kbps when using the H.261 codec.

When connecting to an empty Transcoded see you see me cascaded conference, the first participant may experience:

seeing him/herself but video is frozen when dialing in to the master conference/

occasional "slow entrance" (the video is built slowly) when dialing in to the slave conference.

When using the Transcoded see you see me option, text overlay does not function correctly.

Working with VPS may prove to be unstable and is strongly discouraged. Please contact your local Cisco Customer Support representative for a possible migration plan.

Interoperability

ISDN endpoints cannot send a 4CIF stream.

There is a big delay when sending Far Endpoint Camera Control (FECC) data via a gateway.

Video freezes repeatedly on the ISDN side of a 1920 Kbps call.

The Cisco MCM does not support service prefixes which include the asterisk character (*).

The video image may freeze on TANDBERG endpoints working in asymmetric video encoding mode (sending H.261, receiving H.263). To resolve this issue, ensure that the H.263 scheme on the MCU is set as the first priority, and H.261 is set as the second priority.

Use the mc:g728nonstd Advanced Command if you experience audio problems when using VCON endpoints with the G.728 audio codec. Disable the G.728 codec via the mc:g728std Advanced Command. The default setting for the mc:g728std Advanced Command is Disable. Use the default setting with all endpoints except VCON endpoints.

Far End Camera control (FECC) may not work properly when sent to Aethra endpoints.

Web/Control

We recommend that you use Microsoft Internet Explorer version 5.5 and above. You may encounter some interoperability issues when using Microsoft Internet Explorer version 7 and Netscape Navigator version 7.

When N/A displays in the Customize Views list of the Participant List tab and Statistics tab in the Conference Control interface, statistics reporting is not available for this channel.

Do not manually refresh the Conference Control web user interface between inviting a cascaded conference and until it connects, wait for the auto refresh of the conference control.

In a 4 + 3 layout (Continuous Presence 2 x 2 in one quadrant of another Continuous Presence 2 x 2 layout), video positions are not displayed correctly in the web interface.

We recommend that you do not configure more than 50 services in the Services tab.

The CP4 layout works only with the H.261 video codec. The web application does not enforce the H.261 video codec in cases where you configure the H.263 codec with single screen geometry in the main layout, then add a presentation layout, and then change the video geometry of the main layout to CP4.

Encryption

Encryption does not work with H.323 tunneling.

H.239 Dual Video

When Polycom VSX-7000 does not transmit a presentation, change the presentation layout in the MCU service to 30 fps.

Older versions of Sony endpoints implement a non-standard H.239. Due to this non-standard implementation, the presentation channel will not open when working with endpoints of other vendors.

In a Sony-only environment via the MCU, we have implemented a workaround for this issue. Contact Cisco Customer Support for information on how to enable this workaround.

Sony PCS-1 version 3.01 works with the standard H.239 implementation and the workaround is not necessary.

Resolved Caveats

The following caveats have been resolved since Cisco Unified Videoconferencing 3500 MCU Release 4.4

Improved Conference Control for MCU cascaded conferences.

Voice Activated changes in cascaded conferences are properly handled.

Stable functioning of H.239 in MCU cascaded conferences.

Improved H.239 interoperability with ISDN endpoints joining via the Cisco Gateway.

H.239, H.264 and encryption interoperability with Aethra endpoints operates correctly

Dual video to VCON HD3000 endpoints operates correctly.

H.264 Voice Activated Switching operates correctly.

Border/frame switching on/off operates correctly in Voice Activated conferences.

Reduced MCU vulnerability to Denial of Service-type attacks.

Support for %23-type expressions (instead of #) as defined in RFC 2396.

The Upgrade Utility target IP address is cleaned when the Upgrade Utility is restarted.

Stable functioning of the Administrator web user interface.

SIP registration works correctly.

Improved SIP interoperability with Windows Messenger.

Support for more than two SCCP conferences with the EMP (E).

The MCU no longer intermittently sends out a silent payload.

Troubleshooting

If an error message reports no resources available when trying to create a conference, check whether the appropriate MPs are registered or online including EMP (E) and local MCU MP unit in the Registered MPs tab. Working with VPS may prove unstable and is not recommended.

When the Windows Start Navigation sound is enabled, a continuous clicking sound is heard when the Conference Control interface automatically refreshes. Disable this sound in the Sounds and Multimedia configuration of the Control Panel.

The Conference Control web interface operates in polling mode with updates every 10 seconds. To refresh information on the screen, reselect the tab you are currently viewing. Pressing the browser Refresh button causes you to exit from the Conference Control and displays the login screen.

The Conference Control and Login screens are best viewed in full screen mode (1024 x 768 fps).

The MCU allows you to open multiple Conference Control browser screens at the same time. It is recommended that you close screens in which you are not currently working to avoid confusion and performing operations on the wrong conference.

Cascading between version 4 and version 5 MCU units requires the Cisco Unified Videoconferencing Manager or the Video Administration for Cisco Unified MeetingPlace. Please contact your local Cisco Customer Support representative for additional details.
