New and Changed Features for Cisco Webex Meetings Server Release 4.0MR4
CWMS to Cloud Meetings Migration
We've made migrating to the cloud even easier. Use the Cloud Migration Tool to move scheduled meetings to the cloud, so that your users don't have to reschedule them. Provision your users on Cisco Webex cloud, and then use the tool to step through the process. For more information, see the Administration Guide for Cisco Webex Meetings Server.

What's New in Cisco Webex Meetings Server Release 4.0MR2
This section describes what is new for Cisco Webex Meetings Server Release 4.0MR2.
Important |
The 4.0MR2 software update is only for systems that are currently running Cisco Webex Meetings Server Release 4.0.1.19 and later, or 4.0.1.1110 and later. For information about important new upgrade considerations, see Webex Productivity Tools and Supported Upgrade Paths. |
Health Checker for Mac
To match the functionaly avaible for Microsoft Windows, this maintenance release includes Health Checker for Mac.
Reduced Requirements for Maintenance Mode
To help reduce system downtime, we've further reduced the number of audio settings that require Maintenance Mode for changes. Put the system into Maintenance Mode to change the following audio settings:
- Voice connection using computer
- Transport
- Port Number
- IPv6 Teleconferencing
- System Audio Language
You can change any of the other audio settings, without putting the system into maintenance mode.
Removal of Special Character Support
Webex follows a new approach to generating Personal Room IDs. If a Personal Room ID contains special characters (non-Latin codes), Webex drops the special characters in the string, and keeps only the valid characters.
If the resulting Personal Room ID exists in the system, Webex appends a number to create a unique ID.
For example, “p&hil” become “phil”. If "phil" is in use, the system changes it to something like “phil423”.
Monitor VM Time Synchronization
Cisco Webex Meetings Server now monitors time synchronization for each virtual machine (VM) in the deployment. The primary Admin VM controls and runs the monitoring process every five minutes. The time difference between the primary Admin VM, and any other VM in the deployment, should be less than five seconds. If the time difference is more than five seconds, the system sends an email alert to all Administrators. The email specifies which VM has the problem and what to do, to avoid issues. The system sends an email alert every four hours, until the problem is fixed. This feature can help you to avoid many issues caused by time synchronization problems.
Optimized Grid-View for Low Bandwidth
A low-bandwidth warning appears if your network connection falls below the minimum requirements for video. During low-bandwidth conditions, you may not receive all participant video streams. Prior to this release, the available streams appeared sporadically in the grid view. Cisco Webex Meetings Server now prioritizes the available video streams at the top of the grid.
Updated Browser Support
This maintenance release adds support for the following browsers:
Microsoft Windows
-
Chrome versions 77 and 78
-
Firefox versions 69 and 70
Mac
-
Chrome versions 77 and 78

This section describes what is new for Cisco Webex Meetings Server Release 4.0MR1.
Important |
The 4.0MR1 software update is only for systems that are currently running Cisco Webex Meetings Server Release 4.0.1.19 and later. |
Administrative XML Web Service Failover
We have added a background job to support Administrative XML Web Service (AXL) failover. This feature ensures that if the CUCM Publisher goes down and CUCM subscribers takes over AXL service, CWMS automatically switches to subscribers. This feature eliminates the need to change the LDAP integration for CUCM in Webex Site Administration.
Cisco Webex Meeting Mobile Version
To start and join meetings hosted on a 4.0MR1 site, we strongly recommend that mobile users upgrade their Webex Meeting Mobile applications:
-
Webex Meeting Mobile for Android 39.6
-
Webex Meeting Mobile for iOS 39.6
Health Checker
The in-meeting Health Checker provides an intuitive and easy way to understand the status of your meeting and system performance.
The Connection and Device status indicators are green (good), yellow (there may be potential issues), or red (issues have been found). You can hover over the status for more details. You can even send a problem report directly from the Health Checker. We moved the Audio & Video Statistics link from the Meeting menu to the Health Checker.
When the Health Checker identifies a problem, it provides and summary of the problem and a list of actions that you can take to help solve the problem.
Problem Reporting for Mac OS
This release adds Mac support for Cisco Webex Meetings Problem Reporting. If Mac users experience issues with the Webex Meetings desktop app, they can generate problem reports to assist with troubleshooting.
To generate a report, open the Webex Meetings desktop app and go to
.Restart and Exit Maintenance Mode
After updating the system, Administrators can choose between the following options:
-
Restart—Restarts the system and requires that an Administrator manually turn off maintenance mode.
-
Restart & Exit Maintenance—Restarts the system and turns off maintenance mode, which saves time.
Sign-in History

-
The IP address for their last sign-in
-
The time of their last sign-in
-
The time of their last sign-out
-
The number of unsuccessful sign-in attempts since their last successful sign-in
Take Virtual Machine Snapshots
You can use Webex Site Administration to take snapshots of the system virtual machines. After you put the system in maintenance mode, and specify the vCenter URL and credentials, you can take a snapshot of each virtual machine in a vCenter. If your IRP virtual machines are in another vCenter, you can specify the URL and credentials for the other vCenter and take all snapshots at the same time.
Using vSphere Data Protection to take snapshots is still supported.

Supported Upgrade Paths
This release of Cisco Webex Meetings Server supports upgrades from release 1.5 to 3.0. The following points apply:
-
An upgrade is a replacement of the system to deploy major modifications that we made to the system.
-
An update is an incremental modification of the system. Updates deploy fixes and minor improvements.
-
An update retains all data from the original system. An upgrade retains all data from the original system, except for the logs.
-
You can't change the audio encryption type (Audio Encrypted -AE/Audio Unencrypted -AU) for the system, during an upgrade or during an update. After deployment, the only way to change a system from one type of audio encryption to the other is to deploy a new system.
-
When upgrading, you can't skip a major version of the software and go directly to a companion maintenance release (MR). For more information, see the following table.
Use the following table to determine your upgrade path to Cisco Webex Meetings Server Release 4.0.
Installed Release |
Path to Release 4.01
|
||
---|---|---|---|
2.8 2 |
|
||
3.03 |
|
||
4.0 |
|
The Webex Meetings desktop app replaced Webex Productivity Tools for Cisco Webex Meetings Server 4.0. If you require Productivity Tools as part of your upgrade strategy, only version 2.82.7000.1229 or later is compatible.
Note |
All updates require downtime. For Multi-data centers, you update both data centers simultaneously. |
Caution |
Don't click Restart for one data center until the update for the other is complete, and both display the Restart button. |
Updating Your High-Availability System
For systems with an existing High Availability (HA) system already attached, the HA system automatically updates when you update the primary system. Ensure that all HA virtual machines are turned on and running before you start the update process.
To add a High Availability (HA) system to your primary system, first deploy the HA system. Then update the HA system to the same version as the primary system. The HA system restarts at the end of the update process. We recommend that you wait an extra 15 minutes after the restart, before you begin to add the HA system to the primary system.
For more information, see the Cisco Webex Meetings Server Administration Guide for your release:
Limitations and Restrictions
Audio-only Meetings
Under the following circumstances, a meeting can continue for more than the 24-hour maximum meeting duration:
-
All attendees for a regular Webex meeting are dial in (audio-only).
-
No attendee starts the web portion of the meeting.
In this case, the meeting continues as long as one attendee remains in the conference. If all dial-in attendees disconnect from the conference, the meeting ends within 24 hours of the start time. The meeting ends immediately if the meeting ran past the scheduled end time.
Note |
This scenario applies only to regular Webex meetings joined only by dial-in participants. This scenario does not apply to Personal Conference Number (PCN) meetings, or to regular Webex meetings joined by web participants. |
Internet Reverse Proxy Removal
As part of the Internet Reverse Proxy (IRP) node removal process, the Admin virtual machine sends a remove message to the IRP server. The message removes the IRP server and therefore all external access to the system. The message is sent as clear text, and it is unauthenticated. Well-crafted malicious code could replicate this behavior and lead to a denial of service.
We recommend that you limit access to port 64616, on the IRP node, to the Admin virtual machine only.
macOS 11.x Big Sur
CWMS supports macOS 11.x, subject to the following limitations:
-
The Webex Meetings client application for CWMS isn’t designed for macOS 11.x. We tested for compatibility and made fixes to provide best-effort support.
-
M1 chip support is pending validation testing.
Microsoft Edge Browser
The Microsoft Edge browser does not support the playback of Webex recordings.
Recording Limitations
The maximum recording size, per recording, is 2.2 GB (existing system limit). For Multi-data Centers, ensure that there is sufficient storage capacity available for all data centers. The maximum number of recordings depends on your storage server capacity. You can estimate the required storage server size for a typical five-year period using the following formula:
Estimated hours of meetings that you expect to be recorded per day * 50-100 MB per hour of recording * five years * 24 hours per day * 365 days per year
There are no per-user storage limitations. The system stores recordings indefinitely until users delete them. To prevent important recordings from being accidentally deleted, there is no setting to enable the automatic deleting of recordings. The storage server retains recordings marked for deletion for up to six months. During that time, users can still archive the recordings to other media.
When you configure a storage server and check Record under , the Record setting is a system-wide setting. There are no individual meeting settings or preferences for recordings. You can also enable or disable recording by Session Types, which you assign to users.
Session Types
A session type is a predefined bundle of features and options (a profile) that site administrators can customize and assign to users. The default session (meeting) type is the PRO session type. Because of the relationships between the PRO session type and the custom session types, we recommend that you do not modify the PRO session type. The best practice is to create a custom session type to modify.
SSO and Email Address Changes
With this release, the Identity Provider (IdP) server can use any unique and static Active Directory (AD) field as the NameID for SSO configuration. If you plan to use the email address change feature, the email AD field is not static. Change the mapping for the NameID field on the IdP server to a unique AD field other than email. If you do not plan to use the feature to change email addresses, there is no requirement to change the mapping for the NameID field.
Caution |
If the NameID field is mapped to the email AD field and you change user email addresses, the system creates a new user account for each changed address. If you plan to change the NameID field mapping from email to another field (such as EmployeeNumber), users must prepare for the change. After you update the NameID fields in AD, have the users log in to CWSM before you change the email addresses. Otherwise, when both the NameID and email address change, no attribute matches the CWMS profile. In this scenario, the existing profile loses the ablity to log into the system and the system creates a new profile. |
Outlook synchronizes with the Exchange server once a day. If you change an existing user’s email address on the Exchange server, the change does not immediately propagate to Outlook. Until synchronization occurs, the system receives the user’s former email address and issues a notice that the user cannot be found. A delegate (proxy) user cannot schedule a meeting for the user, or identify them as an alternate host, until after Outlook synchronizes with the Exchange server.
Manually synchronizing the systems does not solve this issue. This limitation is not a CWMS issue; it is the result of Outlook and Exchange design.
See also About SSO Configuration.
TLS Support
This release supports TLS 1.1 and later; TLS 1.0 is not supported, with one exception. Client connections from Cisco Webex Meetings Server (CWMS) to an SMTP server using TLS 1.0 are supported.
vCenter 6.5 Support
When you deploy the CWMS OVA file on vCenter 6.5, the following restrictions apply:
-
Because of browser limitations and the CWMS OVA file size of 16GB, you must deploy the OVA file by using the URL and not the local file upload.
-
Choose the vCenter FLASH based client. This selection is required to successfully populate the vApp properties for VM configuration: hostname, domain, IP address, subnet and DNS configuration.
Virtual Desktop Infrastructure
The following limitations and restrictions are known to affect virtual desktop infrastructure (VDI) environments.
-
Citrix Virtual Apps and Desktops is the only desktop virtualization software supported for this release of Cisco Webex Meetings Server.
-
An architectural limitation of the virtual desktop environment can affect video quality. The frame rate may be low, causing a suboptimal experience when sending video.
-
Some video files cannot be shared in a virtual desktop environment.
-
Remote Access and Access Anywhere are not supported in virtual desktop environments. The underlying Citrix platform removes the Remote Access and Access Anywhere agents after the operating system restarts.
Webex Meetings Desktop Application
The Webex Meetings Desktop Application has the following limitations. Users cannot perform the following actions:
-
Schedule a yearly meeting.
-
Join a meeting using a video address.
-
Schedule or join Personal Room meetings from the Webex Meetings Desktop Application.
-
Schedule Personal Room meetings from Microsoft Outlook.
-
Connect and join meetings from video devices.
-
Connect and share to cloud-registered video devices.
-
Connect and share to Webex Share devices.
-
Receive a callback to a video device during a meeting (Call My Video System).
-
Start or join a meeting from Microsoft Word, PowerPoint, or Excel.
Attention |
Scheduling and editing meetings from Microsoft Outlook for Mac is not supported. As a workaround, users can schedule, edit, and start meetings from your Webex site. |
Upgrade Considerations
The Webex Meetings Desktop Application is not backwards-compatible with earlier versions of Cisco Webex Meetings Server.
After you upgrade your system to CWMS 4.0, you can choose whether to push the application to end users, or to permit them to download it themselves.
If you push the Webex Meetings Desktop Application to users, they must sign in to the application with their existing credentials. This is true, even if they previously chose the remember me and auto sign-in options for Webex Productivity Tools.
If you permit users to download and install the application themselves, Microsoft Windows users must first uninstall Webex Productivity Tools.
If permitted, some users may opt to continue using Webex Productivity Tools. These users will not be able to start instant meetings by clicking the Start Meeting button. A hotfix is available to fix this issue.
Important Notes
About Using Self-Signed Certificates
We strongly recommend using a publicly signed certificate instead of the provided self-signed certificate. User’s browsers trust publicly signed certificates because the list of Root Certificate Authority certificates installed on the computer establishes trust.
For Multi-data Center systems using self-signed certificates, the user receives multiple certificate warnings and must trust and install all certificates to use the system.
When using self-signed certificates, some users might have difficulty joining meetings because browsers by default do not trust such certificates. Users are required to explicitly establish trust in this case before they can proceed to join a meeting on your site. Some users might not understand how to establish trust with such a certificate. Others might be prevented from doing so by administrative settings. Use publicly signed certificates whenever possible to provide the best user experience.
The User Guide provides more information about this issue for users. See the "Meeting Client Does Not Load" topic in the "Troubleshooting" chapter of the Cisco Webex Meetings Server User Guide at http://www.cisco.com/en/us/products/ps12732/products_user_guide_list.html.
Hypervisor Support
Cisco Webex Meetings Server runs on VMware virtual machines.
-
Both VMware vSphere and VMware vCenter are required to deploy Cisco Webex Meetings Server. Using the vSphere client, you deploy the Cisco Webex Meetings Server OVA file on an ESXi host managed by vCenter.
-
Purchase VMware vSphere 5.5, 6.0, or 6.5 for use as the hypervisor platform for Cisco Webex Meetings Server.
-
Buy vSphere directly from Cisco on the GPL (Global Price List). Cisco is an approved VMware partner and distributor. This is convenient for those who want to purchase everything from a single vendor.
-
Purchase vSphere directly from VMware, through enterprise agreements you have directly with VMware.
-
-
Cisco Webex Meetings Server does not support other hypervisors.
-
For more information about hypervisor requirements, see the Planning Guide and System Requirements for Cisco Webex Meetings Server at http://www.cisco.com/en/US/products/ps12732/prod_installation_guides_list.html.

SRTP SIP Call Signaling
Cisco Webex Meetings Server also supports the following crypto ciphers for SRTP calls over SIP line and SIP trunk:
-
AEAD_AES_128_GCM
AEAD is Authenticated-Encryption with Associated-Data, and GCM is Galois/Counter Mode.
-
AEAD_AES_256_GCM
-
AES_CM_128_HMAC_SHA1_80
-
AES_CM_128_HMAC_SHA1_32
Important |
If you have SRTP and AES-GCM configured, check the firmware versions for your IP Phones, before you upgrade to Cisco Webex Meetings Server Release 4.0MR3. Ensure that the IP Phones have the latest firmware—version 12.7.1 or later, or 14.0.1 or later, depending on the model. |
About SSO Configuration
This release supports using any unique Active Directory (AD) field as NameID for SSO configuration. We recommend following AD attributes for NameID for SSO configuration:
-
Email
-
SAMAccountName
-
UserPrincipalName (UPN)
-
TelephoneNumber
-
EmployeeNumber
-
ObjectSid
Mandatory SAML Assertion Attributes
The following SAML assertion attributes are required for the Auto Account Creation feature:
-
lastname
-
firstname
-
email
Important
The email attribute is always required, even if Auto Account Creation and Auto Account Update are disabled in the SSO configuration.
Expanding Your System
If you have VMware snapshots on your existing (pre-expansion) system, remove them before beginning the expansion.
System expansion requires Virtual Machine Disk (VMDK) attaching, from the original system to the target (expanded) system. If you leave snapshots on the original system and attach it to the target system, the target system won't power on because of snapshot inconsistency.
SNMP v2 Community Names
Translated Documentation
Translated documentation for this release of Cisco Webex Meetings Server is published 4–6 weeks after the English-language release.
Known Issues and Notices
Apple iOS 6.x and SSO
There is a known issue with Apple iOS 6.x. Single sign-on (SSO) does not work for internal users of iPad/iPhone who are using the Safari 6 web browser. An Apple defect that is fixed in iOS 7 caused this issue. The Safari bug ID is 13484525.
Audio Configuration
On your audio configuration settings, G.711 provides better voice quality than G.729. See "About Configuring Your Audio Settings" in the Cisco Webex Meetings Server Administration Guide for more information.
Cannot Share .mp4 Video File Format on Windows
When using QuickTime, the following message may appear: "QuickTime failed to initialize. Error # –2093. Please make sure QuickTime is properly installed on this computer."
-
Download the latest version of the QuickTime Player http://www.apple.com/quicktime/download/.
-
Uninstall QuickTime using the Add or Remove Programs control panel. Ensure that you select Uninstall Everything.
-
Delete the contents of the Temp folder, C:\WINDOWS\TEMP (if it exists).
-
Install QuickTime using the version of the QuickTime you downloaded.
-
Restart Windows.
Dashboard Issue Failure to Display Meetings That Have Started
In this release of Cisco Webex Meetings Server, the dashboard can fail to display certain meetings as having started. This issue occurs in the following scenario:
A meeting is scheduled with the Allow participants to join teleconference before host setting enabled. A participant joins the meeting by phone but does not join the web portion. The dashboard should indicate that this meeting has started and has one participant but it does not. This issue can cause users to schedule multiple meetings resulting in performance issues.
Dial-in and Dial-Out Connections to an In-Progress Meeting
When a meeting fails over from one data center to another, the dial-in and dial-out connections to that meeting do not automatically reconnect. To reestablish the connections, participants hang up and manually dial back in.
-
The installed system is a large MDC.
-
The meeting is started while one of the data centers is in Maintenance Mode or is powered down.
-
When, after Maintenance Mode is turned off or the data center is powered on, another data center is powered off or placed into Maintenance Mode.
IP Communicator 7.0.x Endpoints
IP Communicator 7.0.x endpoints joining CWMS meetings can introduce audio quality issues (echo and other noises) to a conference if either of the following conditions occur:
-
IP Communicator is not muted.
-
A participant using IP Communicator becomes the active speaker.
To prevent this issue, fine tune the IP Communicator environment (for example, the headset, microphone, and speaker) or use a different traditional phone.
Keeping Your Hostname While Changing Your Virtual Machine IP Address
Never change the DNS entries for the hostnames that are configured in your deployment. You can change the hostname of a virtual machine that is part of your deployment. The corresponding IP address is picked up automatically from the DNS. To change the IP address of a virtual machine and keep the same hostname, perform the following steps:
-
Configure a temporary hostname in the DNS.
-
Change the hostname of the virtual machine to the temporary hostname that you configured.
-
Take the system out of maintenance mode for the new hostname change to take effect.
Your original hostname is not part of the deployment after this change.
-
Change the IP address of the original hostname in the DNS to the new IP address.
-
Change the temporary hostname of the virtual machine to the original hostname.
-
Take the system out of maintenance mode for the hostname change to take effect.
Now the original hostname is configured with your new IP address.
Update from 3.0 Patch 1 Fails
Updating from Release 3.0 Patch 1 (3.0.1.33) fails because there is incorrect data in the cwms.pub file. Before you update from 3.0 Patch 1, apply the following workaround for this issue.
-
Go to https://bst.cloudapps.cisco.com/bugsearch/bug/CSCvj70890.
-
Download the attached file: fix_update.zip and copy it to /archive directory on the primary Admin VM.
-
Use SSH to connect to the primary Admin VM, and navigate to the /archive directory.
-
Unzip the file: unzip fix_update.zip.
-
Make the unzipped file executable: chmod +x fix_update.
-
Run the executable: ./fix_update.
-
After you see the Success message, proceed with the update.
