Compatibility Matrix and Supported Upgrades
We recommend that you run upgrade and downgrade procedures from a machine located on the same network as your MCU to ensure that there are no failures due to network connectivity problems.
Do not simultaneously run more that one upgrade utility per PC.
Upgrading from a previous build of MCU Release 5.x to MCU Release 5.6
All products working together with MCU Release 5.6 must be upgraded to Release 5.6.
You cannot upgrade directly from MCU Release 5.0 to Release 5.6. Upgrade initially to Release 5.1.1 and then to Release 5.6
Step 1 Save the current MCU custom configuration by clicking Export on the MCU web user interface toolbar to export the MCU configuration to a *.ini file.
Step 2 Burn the MCU Release 5.6 application with the MCU default configuration.
a. Run the MCU v5.6 Upgrade Utility.
b. Provide the target IP address.
c. Click Customize.
d. If you are upgrading from MCU versions prior to MCU version 5.5.3, ensure that MCU Factory Default Configuration option is not selected.
e. Ensure that all other Customize options are selected, including the Default MCU Configuration option but only one of the additional fonts if desired.
f. Click Upgrade to perform the upgrade procedure.
g. Wait while the MCU performs the upgrade procedure and resets.
Note This might take a few minutes. Please wait until the procedure is fully completed and the Upgrade Utility reports that the upgrade has been performed successfully.
After reset, the latest version is installed on the MCU.
Step 3 (Optional) Restore a previously saved MCU custom configuration by clicking Import on the toolbar of the MCU web user interface to import a previously saved MCU Release 5.x configuration .ini file.
Upgrading from a previous build of EMP Release 5.x to EMP Release 5.6
Step 1 Use the EMP Upgrade Utility to burn the version of the EMP software that operates with the version of the MCU.
After burning, the Upgrade Utility will reset the platform.
Step 2 After reset, the latest version is installed on the EMP.

New and Changed Information
Cisco Unified Videoconferencing 3500 MCU Release 5.6 introduces these features:
•Simplicity—Auto Attendant and Video IVR allowing direct dialing to the MCU using a leading number or an IP address. The use of video messages makes the process simpler than ever.
•Video quality improvements and additional resolutions support.
•Lecturer Mode—Enables all participants to see the conference lecturer in a full screen HD display, while the lecturer sees all the other conference participants in a HD Auto Switch display.
•Support for call rates of up to 4096 Kbps.
While configuring Cisco Unified Videoconferencing 3500 MCU Release 5.6, observe these recommendations:
•The number of prefixed services—This number should not exceed 30. Defining a higher number of MCU prefixed services may prevent you from properly saving the MCU configuration to file.
•In order to assure successful IP dialing when MCU is not registered with a gatekeeper, configure the MCU as follows:
–Disable the Register Conf ID option
–Use a Gatekeeper IP address different than 0.0.0.0 (or ending in .0); for example, 126.96.36.199.
For information about all available features and benefits, see the data sheet for Cisco Unified Videoconferencing 3500 MCU at http://www.cisco.com/en/US/products/hw/video/ps1870/products_data_sheets_list.html.
Note We recommend that you set the Ethernet port speed and duplex parameters of both the MCU/ EMP boards and the switch to Auto. Set these parameters to 100 Mbps full duplex only if you experience port speed negotiation problems. Ensure that the Ethernet port speed and duplex parameter values on the MCU and the switch are identical.
Using Bug Toolkit
Known problems (bugs) are graded according to severity level. These release notes contain descriptions of the following:
•All severity level 1 or 2 bugs.
•Significant severity level 3 bugs.
•All customer-found bugs.
You can search for problems by using the Cisco Software Bug Toolkit.
Before You Begin

The caveats in Table 1 describe possible unexpected behavior in the latest Cisco Unified Videoconferencing 3500 MCU release. These caveats might also be open in previous releases. Defects are listed in order of severity and then in alphanumeric order by defect identifier.
This section lists caveats that are resolved in Release 5.6 but that might have been open in previous releases.
Defects are listed in order of severity and then in alphanumeric order by defect identifier. 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 2 lists the caveats that were resolved in Release 5.6.

See the Troubleshooting Guide for Cisco Unified Videoconferencing 3500 MCU Releases 5.5 and 5.6 at: http://www.cisco.com/en/US/products/hw/video/ps1870/prod_troubleshooting_guides_list.html
In the "Enabling and Disabling High Definition Continuous Presence" section of the Configuration Guide for the Cisco Unified Videoconferencing 3545 MCU Release 5.6 (http://www.cisco.com/en/US/docs/video/cuvc/5_5/mcu/3545/configuration/guide/basic_v5_5.html#wp1054554), this information was omitted:
Note High Definition Continuous Presence is disabled by default. After enabling it, you must change service prefix 81 to 720p resolution. Enabling HDCP alone results in the service limiting the resolution to 4CIF.
This information was omitted from the Configuration Guide for the Cisco Unified Videoconferencing 3545 MCU Release 5.6 and from the Configuration Guide for the Cisco Unified Videoconferencing 3515 MCU12 and MCU24 Release 5.6:
•MCU registrar or proxy registration to Cisco Unified Communications Manager is not supported. All SIP MCU deployments with Cisco Unified Communications Manager are to be by SIP trunk only.
You must configure the SIP trunk on Cisco Unified Communications Manager to interoperate with SIP MCU.
•Under certain conditions sub mode control (SMC) interaction with the LifeSize HD endpoints running v3.5 software is suboptimal, which results in not being able to lock in the correct frame rate and resolution. In this case, a black screen for a particular endpoint video is displayed.
To solve this problem, disable the SMC function on the MCU by sending the enablesubmodecontrol advanced command with parameter set to 0 to the MCU. This action stops reliance for the endpoint to provide SMC information.
The correct supported combination for SMC use is to upgrade the LifeSize endpoint software version to v3.6 and use the MCU with enabled SMC function.
This information was omitted from the Installation and Upgrade Guide for Cisco Unified Videoconferencing 3545 MCU Release 5.6 and from the Installation and Upgrade Guide for Cisco Unified Videoconferencing 3515 MCU12 and MCU24 Release 5.6:
•Due to a time error between password timeout and password creation time, if the password expiration timeout is set to 1 day, you cannot log in for a short time because the MCU considers the password expired before the timeout actually elapses.
To troubleshoot, enable security via MCU web interface, and set password expiration to 1 day. Log off, wait approximately 22 hours, and then log on to MCU. After you log on, a message is displayed informing you that your password has expired, but there is no need to change the password immediately. If you attempt to change the password, this error is displayed: "Your password can't be changed because it has been changed within the last 24 hours".
