October 2020 (40.10) Announcements

Firefox Proxy Configuration Change

Starting with this update, we will no longer support proxy setup within the Firefox browser, and instead will follow the system proxy settings.


Users who previously managed their proxy setting in Firefox will need to set up their proxy in the system proxy settings to start and join meeting.

Simplified Auto-Delete Meeting Logic

Starting with the November 2020 (40.11) update, site administrators will have the ability to configure the automatic meeting deletion policy for non-recurring meetings. Hosts will not need to update the meeting auto deletion behaviors.

Support for Additional Platforms in VDI

In the October 40.10 update, we are excited to announce the availability of Citrix for iGel for the Cisco Webex Meetings desktop app on Virtual Desktop Infrastructure (VDI) environments. As a reminder, Citrix for Windows and Linux, and VMWare for Windows was available in the 40.8 update.

Host Key Rotation

To prevent unauthorized use of the host key, the host key for a meeting will now automatically renew when a meeting ends after its scheduled time. This change is applicable for all Webex sites for meetings, events, and training sessions and will take effect on October 16, 2020 during your site's change window. This change will apply to all existing and new sessions scheduled after October 16, 2020, including any recurring sessions.

If for some unexpected reason we have to revise the date for this change, we will update this announcement in What's New for the Latest Channel of Webex Meetings and What's New for the Slow Channel of Cisco Webex Meetings.

End of Support for Cisco Webex Scheduler with Google Chrome Extension, Webex Scheduler for Internet Explorer, Webex Integration to IBM Lotus Notes, Skype for Business, and IBM Sametime

We will be officially retiring support for the Cisco Webex Scheduler with Google Chrome Extension, Webex Scheduler for Internet Explorer, Webex Integration to IBM Lotus Notes, Skype for Business, and IBM Sametime on December 31, 2020. They will no longer be available for download from January 1, 2021. Users of Cisco Webex Scheduler with Google Chrome Extension should move to the newer version of Cisco Webex for G Suite add-on.

September 2020 (40.9) Announcements

MP4 Recordings Default in Webex Meetings 40.10

In the upcoming October (40.10) update, all new recordings in Webex Meetings will be stored in MP4 format, either in the cloud or locally as selected at the site or host level, with a video-centric experience. By standardizing the recording format, you'll have a wider choice of playback tools, better security and an easier collaboration experience even after your meetings. Existing ARF and WRF recordings can still be downloaded or played at the Webex site. For more information regarding video centric recording, go to Video-Centric Network-Based MP4 Recordings in Webex Meetings and Webex Events.

Attendee ID Length Changes

The minimum length of the Attendee ID is now 6 digits. Attendee ID is used to bind a PSTN caller's Audio to the Meetings client presence. The longer ID length provides better security and decreases the chances of rogue caller binding with someone else's Attendee ID.


This change will be applicable to Webex Meetings, Webex Events, Webex Support, and Webex Training.

Short Video Address as Default

Short video addresses have been available since the 39.11 update and have been instrumental in making it faster to join meetings using a video system. However, it has been an opt-in capability so far. In the upcoming October (40.10) update, we will switch to a short video address format as the default. Site administrators will always be able to control the enablement of this feature.

August 2020 (40.8) Announcements

End of Support for Windows 7 and Internet Explorer 10

In the upcoming September 2020 (40.9) update, Cisco Webex will officially end support for the Windows 7 operating system and the Internet Explorer 10 browser.

Cisco will no longer provide bug fixes or updates for this operating system and browser. While users on these platforms will not be prevented from joining or starting meetings for now, we can no longer guarantee a fully functional operation. To have the best meeting experience possible, plan to upgrade your operating system and browser.

Please note that we are actively working on establishing dates to prevent the users on these platforms from joining Webex meetings in the future. We will provide advanced notice once we have the dates.

Classic View Deprecation for Meetings

Starting with the September 2020 (40.9) update, we will be deprecating our Classic View portal for all Webex Meetings capabilities. Customers will continue to have access to the Webex Events and Webex Training capabilities, however they will no longer be able to access their Webex Meetings-specific functions through the Classic View interface. See details for What's Supported in Modern View.

July 2020 (40.7) Announcements

End of Support for Windows 7

In the upcoming September 2020 (40.9) update, Cisco Webex will officially end support for the Windows 7 operating system and the Internet Explorer 10 browser. To have the best meeting experience possible, plan to upgrade your operating system and browser in advance!

Easy Access to End-to-End Encryption Session

Cisco Webex has always supported end-to-end encryption for meetings. Around mid-July we will enable the end-to-end encryption session type for all sites. Only administrators will see this new session type in the Webex Control Hub or site administration portal. Administrators must make the end-to-end encryption session type available to users if needed. With this change, you will not need to contact customer care if you would like to use end-to-end encryption for your meetings. We will shortly publish the exact availability date for this new session type. Please note some meeting features are not supported with end-to-end encryption. Read full details here.

Directly Get July Update (40.7) Due to Delay In June Update (40.6)

As you know, Cisco Webex delivers new and enhancements to customers in monthly updates. We have experienced a delay in delivering our June update (version 40.6). And as a result, some of our customers may directly get our July update (version 40.7). You can view the monthly maintenance and upgrade schedules for your site (based on your cluster) here at Service Upgrades and Scheduled Maintenances.

Meetings update to AES-256-GCM Cipher Suite and Mobile apps-

In the coming weeks, we intend to enable support for AES-256-GCM cipher suite for the Webex sites. Precise scheduling will be announced shortly. When your site is enabled for AES-256-GCM support then all of your Webex mobile users lower than the 40.6.1 version of the mobile app will be prompted to upgrade to the latest mobile app version before joining their next meeting. Customers using mobile device management (MDM) must deploy the new app prior to the AES-256-GCM cipher suite enablement, or their meeting join experiences will break on their MDM controlled devices.

Classic View Deprecation

Starting with the September 2020 (40.9) update, we will be deprecating our Classic View portal for all Meetings capabilities. Customers will continue to have access to the Events and Trainings capabilities, however they will no longer be able to access their Meetings specific functions through the Classic View interface. More details to follow in a later release.

WBS40.6 Announcements

WBS40.4 Announcements

Meeting Number Size Increase

Due to unprecedented circumstances resulting from Covid-19, a large number of educational, commercial, and public institutions have turned to the Webex Meetings business suite for remote working. With a tremendous increase in meeting traffic, Cisco Webex is quickly running short of meeting numbers. To address this challenge, Webex Meetings, Events, Training and Support sessions will now be increased from 9-digits to 10-digits first, and then will expand to 11-digits shortly afterwards.

Cisco will ensure that desktop apps, mobile apps, web app, video devices, our APIs, and our out-of-the-box integrations with Jira, Microsoft Teams, Slack and others are fully compatible with the meeting number increase. If you are using Webex APIs with your applications, we request that you test and ensure your applications are working with this change. This change to 10-digit meeting numbers is scheduled to begin on May 15th, 2020, and you can find the date for your site based on it's cluster at status.webex.com/maintenance.

WBS40.2 Announcements

Version Numbering Change for the Next Webex Meetings Update

We’re changing the Webex Meetings version numbering to better align with the calendar month when the update is generally available to customers. With the new version number format, the WBS40.3 version number will be skipped, and the update following WBS40.2 will be WBS40.4.

The version number format is <major version>.<minor version>, with the minor version indicating the month when an update first becomes generally available to customers, per the deployment schedule. For example, WBS40.4 will be generally available to customers in April.

Hosts on New Webex Sites Can't Edit Event and Training Session Email Templates

Hosts on newly provisioned sites are no longer able to edit their Webex Events or Webex Training email templates. Existing Webex sites aren’t impacted by this change, and hosts on these sites can continue editing their templates as before.

Automatic Linking of Sites and Users to Cisco Webex Reminder

As of our WBS40.1 update, we announced that your site and users will be automatically linked with Cisco Webex Control Hub. The WBS40.1 update is expected to begin deployment on Jan. 17, 2020 and will continue deployment based on the normal update schedule. Approximately a week after your site is updated to WBS40.1, it will be automatically linked to Cisco Webex Control Hub. The exact schedule for WBS40.1 and automatic linking will be published later.


If your site is hosted in one of Cisco’s EU data centers, then this notification doesn’t apply to you. We’ll send another notification with the details of automatic linking specific to Webex sites hosted in EU data centers. Additionally, this notification is not applicable to “Shared Sites” managed by Cisco partners.

Linking your sites and users to Webex Control Hub is necessary for getting the best out of Webex Meetings. Through linking, administrators get access to excellent analytics to better understand the utilization of their Webex Collaboration portfolio. They can also troubleshoot Webex Meetings problems in near real-time. Also, your users get exciting features like People Insights, the ability to search for video devices to connect to, and RESTful APIs.

After site and user linking, Control Hub becomes the single starting point for all administrative tasks. You can cross launch from Control Hub into Webex Site Administration for simplified site and user management.

As announced earlier this year, Cisco has acquired an artificial intelligence technology company called Voicea. Cisco is working on enhancing Webex Meetings to include voice-driven automatic meeting notes and highlights. This offering is expected to be available shortly and will only be delivered to linked sites.

We’re fully committed to providing the most secure meetings with the best cutting-edge technology in the industry. To fully serve you with that goal, linking your site and users with Webex Control Hub is now a mandatory requirement.

If your site users aren’t linked, please review the scenarios below, as your site will fall into one of these scenarios and the appropriate action will happen automatically:

  • Your site is linked but all the users aren’t linked- the new automatic linking flow will automatically link the remaining users. Click here for more information

  • Your users and site aren’t linked, and you see a new UI in Webex Site Administration for selecting an organization- linking your site and users with Webex Control Hub requires the existence of a Control Hub organization. Our algorithms determine your potential organization based on your orders of Cisco collaboration services, your administrators’ email addresses, and your users’ email addresses. However, based on your specific situation, we need your input on selecting the organization that you prefer. As advised in the WBS39.9 release notes, by Dec. 15, 2019, site administrators will see a new UI in Webex Site Administration to select the target organization for site linking. Select the appropriate organization and continue linking before the WBS40.1 update. After the update, if your site isn’t linked, the automatic linking flow will pick the organization that our algorithm determines as the default. Click here for more information

  • Your users and site aren’t linked, and you don’t see a new UI in Webex Site Administration for selecting an organization- Cisco’s algorithms can accurately determine a target Webex Control Hub organization for your site. Your site and users will be automatically linked about a week after the WBS40.1 update. The exact schedule will be published later. Click here for more information on what to anticipate.

Contact your Customer Success Manager or Cisco Support for any questions or concerns.

WBS39.11 Announcements

Reminder for Enterprise Deployment Configuration Requirements

In preparation for exciting new features that we’re releasing in the upcoming updates, we would like to remind administrators to verify the following configurations in their networks:

  • Allow access to the Webex IP blocks as documented in our network requirements. If some IP blocks aren’t reachable from your network, then upcoming features won’t work and will result in one-way media issues.

  • Ensure Expressway-E’s are configured with TLS connection in the DNS zone pointed towards Webex. This ensures that a secure connection from the enterprise uses SIP TLS for signaling and sRTP for media.

Reminder for Mandatory Password Enforcement


This announcement only applies to the latest Webex Meetings sites. Lockdown sites aren't affected.

Users must have Webex Meetings Productivity Tools WBS39.10.2 to avoid impact on their existing meetings.

As announced on Nov. 6, 2019 with the WBS39.10 release notes, starting from Jan. 10, 2020, all Webex sites are going to be configured to automatically add passwords for any new meetings, events, or training sessions. Below is the relevant section copied from the WBS39.10 release notes, and this article has the full details of password enforcement.

The most effective step to strengthen the security of your meetings is to create a strong password. Passwords protect against unauthorized attendance, so only users with access to the password can join the meeting.

Starting from Jan. 10, 2020, all Webex sites are going to be configured to automatically add passwords for any new meetings, events, or training sessions.

Password enforcement doesn’t affect the meeting join experience of attendees. Participants can easily join a meeting by clicking on the URL in the meeting invitation through email or the Webex Meetings mobile app, without requiring passwords. Users who enter the meeting number on the web page to join a meeting are required to enter passwords.

Password enforcement is only available for meetings scheduled after Jan. 10, 2020.

Cisco won’t enforce password requirements for attendees dialing in to the meeting through a phone or video device. We highly recommend that administrators configure their sites to require passwords for attendees joining through phones or video devices as well.

To support this change, with the WBS39.10 update, site administrators can’t disable passwords for meetings, events, and training sessions if their site has enabled passwords for them.

Early Announcement - Version Numbering Change for Webex Meetings

We’re changing the Webex Meetings version numbering to better align with the availability of updates to our customers. With the new version number format, the next monthly update will be WBS40.1 instead of WBS39.12.

The version number format is <major version>.<minor version>, with the minor version indicating the month when an update first becomes available to customers, per the deployment schedule. For example, WBS40.1 will begin customer deployment in January, and will be deployed to the different clusters as scheduled.

Early Announcement - Automatic Linking of Sites and Users to Cisco Webex
