Introduction

The Cisco Unified Videoconferencing 5000 Series MCU is a high-performance, multipoint video conferencing and media processing system that provides extensive audio and video processing capabilities and web-based conference monitoring and management.

---

Note Web user interface Conference Control functions are not supported for Skinny Call Control Protocol (SCCP) conferences.

---

The Cisco Unified Videoconferencing 5000 Series MCU supports a wide range of telephony protocols and media communication networks and is interoperable with other video conferencing network devices.

Cisco Unified Videoconferencing 5000 Series MCU provides a new level of media processing and density. The new platform supports video conferencing from entry-level desktop systems to high-end High Definition room systems, providing a true High Definition solution.

For information about all available features and benefits, see the data sheet for Cisco Unified Videoconferencing 5000 Series MCU at

Resolved Caveats

This section lists caveats that are resolved but that may have been open in previous releases.

Defects are listed in order of severity. Because defect status continually changes, be aware that this document reflects a snapshot of the defects that were resolved at the time this report was compiled. For an updated view of resolved defects, access the Bug Toolkit (see the "Using Bug Toolkit" section).

Table 1 Resolved Caveats for Cisco Unified Videoconferencing Manager Release 7.2  

Identifier	Severity	Component	Headline
CSCti03754	1	mcu	CUVC not accepting calls.
CSCtg53466	2	mcu	No video send from MCU to Tandberg endpoint.
CSCtg68494	2	mcu	Black Screen on Speaker's screen when she or he speaks.
CSCth46813	2	mcu	GT: Continuous lipsync - All CTS endpoints had lipsync issues.
CSCtf18316	3	mcu	CTMS-CUVC link fails with 503 error when CUVC maxed VC endpoints.
CSCtf31876	3	mcu	Slow/no switching of active speaker VC endpoint.
CSCth52901	3	mcu	Conference failed when BW is set to 384k.
CSCti95943	3	mcu	Video bitrate not sustained on calls to CUVC (RTT goes very high)
CSCtj33500	3	mcu	Poor video quality seen on certain TBG EPs with processing "restraints".
CSCtn17984	3	mcu	Advanced Invitation - gives an error.
CSCtf64195	4	mcu	Audio packets counts stays at 1 for MCU to endpoint streams.
CSCth14914	4	mcu	MVP restarted during conference.

Closed Caveats

These caveats have been closed, which means that Cisco acknowledges that there is a problem but chooses not to fix it. See the "Using Bug Toolkit" section for information about accessing these caveats.

Table 2 Closed Caveats for Cisco Unified Videoconferencing Manager Release 7.2

Identifier	Severity	Component	Headline
CSCtn15503	2	mcu	MCU failed to reboot. Workaround: Reboot the MCU manually.

Troubleshooting

Firefox Support

When using the Firefox web browser to access the CUVC MCU, a rare access error might be seen. Logging in again to the CUVC MCU resolves it.

E-20 Operation

E-20 works incorrectly towards the MCU. There is a workaround on Cisco Unified Communications Manager. A configuration note has been included in CSCtn47361.

Omissions

Setting the Maximum MTU Size on the CUVC

The CUVC's maximum MTU size determines the largest size of the data packets that can be sent by the CUVC. If the size of the data packet is larger than the maximum allowed by your network routers, the packet is split. This fragmentation can significantly impact video quality. Therefore it is important to set the MTU size of the CUVC to be in step with the router size. For example, if the CUVC's MTU size is set to 1500 while the network routers are configured to 1360 packet sizes, you can improve video quality by setting the CUVC's MTU size to 1360 to match the routers.

Procedure

---

Step 1 Select the icon.

Step 2 Select Advanced Parameters.

Step 3 Locate the CLI section and select More.

Step 4 Enter setmtusize in the Command field.

Step 5 Enter the value of the maximum size of the CUVC's data packets in the Value field.

The default value is 1360.

Step 6 Select Execute.
