Open Caveats for Cisco Unified Videoconferencing 3500 MCU Release 5.0

Open Caveats for Cisco Unified Videoconferencing 3500 MCU Release 5.0

This section lists possible unexpected behaviors by Cisco Unified Videoconferencing 3500 MCU Release 5.0.

MCU known issues are included in the following categories:

Endpoint Information Display in MCU Conference Control

Local View

H.243

DTMF Conference Control

Encryption

Configuration

Video Quality

H.239

Gateway Connectivity

Cascading

SCCP

T.120

Endpoint Information Display in MCU Conference Control

The information icon for participants in child conferences does not function. Clicking on it does not perform any action.

SIF resolutions appear as CIF resolutions on the statistics page.

Connections with asymmetric resolution (4CIF/CIF) inaccurately show 4CIF for both directions.

Local View

Local view, defined in the custom layouts section of the advanced video settings, does not appear in the conference control and cannot be used.

H.243

If the H.323 registration mode is set to gateway when enabling H.243, then in cascaded conferences endpoints appear twice in the conference control. To resolve this, either disable H.243 or change H.323 registration mode to MCU.

H.243 conference control may not function with some ISDN endpoints that are connected through a gateway.

When H.243 is enabled, Far End Camera Control (FECC) to some TANDBERG endpoints may not function. To resolve this, disable H.243.

DTMF Conference Control

In some cases, the MCU spontaneously announces the conference control menu. When this occurs, press `#' to exit the menu.

Encryption

Encryption does not function with TANDBERG endpoints that support both AES and DES and that are configured to only enable DES. To resolve this, enable AES in the endpoint.

Encryption and H.239 do not function together.

Configuration

Using `0' as the service prefix causes unpredicted results. Refrain from using `0' as the service prefix.

Using special characters (`<', `>', `&') in the service description causes unpredicted results. Refrain from using those characters in the service prefix.

Video Quality

Joining more than 12 4CIF endpoints into a full-screen conference may result in significant delays.

H.239

When working with H.264 and presentation view enabled services, some TANDBERG or Aethra endpoints may stop sending the main video when the presentation channel is opening. Use the relevant workaround for the following endpoints

TANDBERG MXP-Enable H.239 on the endpoint.

TANDBERG classic-Remove H.264 from the service or the endpoint.

Aethra-Remove H.264 from the service or the endpoint.

In cascaded conferences with H.239, make sure that only one presenter is active at any given time. Having simultaneous presenters in a cascaded conference may result in the display of more than one presentation to participants. To immediately solve this issue, keep one presentation open and close all other presentations. For details about how to fix this issue permanently with an advanced command, contact Cisco Technical Support as described at "Obtaining Technical Assistance" section.

Some ISDN endpoints connected to the MCU via a gateway may fail to send the presentation channel when using H.239 XGA.

When working with H.239 XGA in a conference including Sony and Polycom or Sony and TANDBERG endpoints, the presentation video from the Polycom or TANDBERG endpoint may not appear on the Sony endpoint.

Gateway Connectivity

This version of the MCU does not function well with ISDN gateway downspeeding or resync. Make sure to disable downspeeding on the gateway.

Cascading

In a cascaded conference, the conference control of the child conference does not indicate the identity of the active speaker. A workaround is to view the conference from the parent MCU that does display this correctly.

SCCP

When connecting Sony PCS1 in SCCP mode using H.264, video may not open. A workaround is to use H.263 when connecting Sony PCS1 using SCCP.

Using the TANDBERG Transfer button in an SCCP conference with only one participant results in a video freeze or no video. This does not happen in conferences with more than one participant.

When adding a new SCCP service, an irrelevant error message may display. To resolve this issue, and enable the creation of the service, open the Advanced management and security dialog box, and then press OK.

Configuring SCCP services to work in audio mode only may result in an MCU crash. Please note that this does not apply to a video SCCP service that can accept audio calls.

T.120

T.120 does not function across cascaded conference

The Join Data Conference button on the MCU conference control page allows users to join T.120 data conferences from the computer running the conference control. This button is currently not available in V5.0 and will be re-added in a later patch.

Troubleshooting

For troubleshooting information, see the Troubleshooting chapter in the Administrator Guide for Cisco Unified Videoconferencing 3515 MCU12 and MCU24 Release 5.0 and Administrator Guide for Cisco Unified Videoconferencing 3545 MCU Release 5.0 at the following URL:

http://cisco.com/en/US/products/hw/video/ps1870/prod_maintenance_guides_list.html

Tips

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.
