December 2021 (41.12) Announcements for Slow Channel

End of Support for Windows 7.x and Windows 8.x Operating Systems

In the January 2022 (42.1) update, Webex will officially end-of-life support for Windows operating systems earlier than Windows 10. Users on Windows 7 and Windows 8/8.1 may continue to be able to start or join meetings. However, for the best experience, we recommend upgrading to the latest version of Windows. We’ll no longer provide bug fixes or updates for operating systems earlier than Windows 10. To have the best experience possible, plan to upgrade your operating system before October 2021. See our system requirements help article.

End of support for Internet Explorer 11

In the January 2022 (42.1) update, Webex will officially end-of-life support for Internet Explorer 11. While users may still be able to start or join meetings using this browser, we’ll no longer provide bug fixes or updates, and recommend using a supported browser version for the best experience.See our system requirements help article.


For webcast attendees, starting February 2022, Internet Explorer 11 is no longer supported. Attendees are prompted to change to a supported browser, when necessary.

Video mesh Cloud Cascade port changes

Video mesh is pushing an update in early January 2022, which requires open destination port ranges UDP 50,000 - 53,000 for the Media Cloud Cascades. Make sure that the UDP 50,000 - 53,000 port ranges are opened up in your firewall configuration. Failure to do so results in service disruption of the Video mesh solution when the software update with the new port ranges for cloud cascade is pushed out.

Today these port ranges are utilized by the Expressway to Webex Cloud (Webex destination port range): UDP 49152-59999 (Network Requirements for Webex Services), so these port ranges should already be opened. If that is the case, no action is required, but in case they aren't, make sure that they are opened up by January 2022, to avoid any disruption in the proper function of the video mesh solution.

August 2021 (41.8) Announcements for Slow Channel

Easy to Use Audio Mute State Management Between Webex Devices and Apps

We’re happy to announce the BETA of a much-improved audio mute state management between on-premises registered Webex devices and the app.

You have probably experienced the dreaded double-mute situation, so as a host on the Webex app you’re trying to unmute a user on a video device who has also muted themselves using the mic button on their device. They will see a message to unmute themselves using DMTF-*6 command and will also need to use their device's mic button to unmute.

We’re improving this experience where you won’t have a double-mute situation again. If you want to unmute a video device user, simply tap the mic button on your app's participant list. Users on Webex video devices see a request to unmute themselves, and they can choose to do so as they see fit. When they do unmute themselves, their status on the app's participant list will be updated accurately.

When a meeting is setup in moderated unmute mode, hosts on Webex app can continue to mute and unmute video device users directly from the app. There is no request to unmute and response flow. Keep in mind that in this mode, if a user on a video device uses their local mic button to control their mute state, this isn’t reflected on the Webex app participant list.
