Table 1 Known Issues for Cisco IPVC 35xx MCU Release 4.2

Category
Description

Encryption

Encryption does not work with H.323 tunneling.

General

You can simultaneously use dual protocols (SIP and H.323) on hardware versions ending in B06 or later. View the hardware version number in the Hardware version field of the Basics tab in the Cisco IPVC MCU board interface.

General

EMP card cannot occupy a system slot in the chassis.

General

When connecting a Cisco IPVC MCU configured as MP only to MCU-15, MCU-30 or MCU-60, the maximum call capacity is 26, 45 and 90 respectively, not 150.

General

Web conference control performance on PCs with low CPU and very large conferences may be slow.

General

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

General

When changing the user name or password that is used to log in to the system, you cannot perform chairman operations in the conference control until logging out and logging in again with the new user information.

General

When changing the Cisco IPVC MCU security mode from High or Maximum to Standard, you must restart the Cisco IPVC MCU to be able to connect by using Telnet.

General

When Preserve Local View is applied to the child view, dynamic layout does not work for a child view.

General

If video output is set to more than 1000 Kbps, video input can be limited when using H.261 and H.263 or both codecs with specific layouts.

General

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.

General

When connecting to an empty Transcoded see you see me cascaded conference, the first participant experiences the following behaviors:

When dialing in to the master conference, the user sees self-view, but video is frozen.

When dialing in to the slave conference, the user experiences occasional slow entrance (video builds slowly).

General

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

H.239 Dual Video

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

H.239 Dual Video

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

In a Sony-only environment via the Cisco IPVC MCU, a workaround for this issue has been implemented.

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

Interoperability

ISDN endpoints cannot send a 4CIF stream.

Interoperability

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

Interoperability

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

Interoperability

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

Interoperability

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 Cisco IPVC MCU is set as the first priority and that H.261 is set as the second priority.

Interoperability

When using multiple video encoding modes, we recommend that you define codecs in decreasing numerical order. For example, in the View Settings dialog box of the MCU Services tab, define an H.264 video scheme before you define an H.263 video scheme.

Interoperability

If you experience audio problems when using VCON endpoints with the G.728 audio codec, use the mc:g728nonstd Advanced Command. To disable the G.728 codec, use 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.

Interoperability

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

Web Control

To reconfigure the service profile processor definition from MP to Auto in the Conference View settings, you must delete the current service profile and create a new service.

Web Control

We recommend that you use Microsoft Internet Explorer version 5.5 or a later version. You may encounter some interoperability issues when using Netscape 7.0.

Web Control

When logging on to the Cisco IPVC MCU web interface, you may hear the Windows operating system audio error indication.

Web Control

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.

Web Control

Do not manually refresh the Conference Control web user interface between inviting a cascaded conference until it connects; wait until the conference control auto-refreshes.

Web Control

In a 4 + 3 layout—Continuous Presence 2 x 2 in one quadrant of another Continuous Presence 2 x 2 layout—video positions do not display correctly in the web interface.


Troubleshooting

If an error message reports no resources available when trying to create a conference, check in the Registered MPs tab whether the appropriate MPs are registered or online, including VPS, EMP, DCS, and local MCU MP unit.

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 and updates every 10 seconds. To refresh information on the screen, choose again the tab that 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 Cisco IPVC MCU allows you to open multiple Conference Control browser windows at the same time. To avoid confusion and performing operations on the wrong conference, we recommend that you close windows in which you are not currently working.
