Learn about the system requirements for the Cisco Webex Video Platform.

Microsoft Internet Explorer

The minimum supported OS for Internet Explorer 10 is Windows 7. If you are on an earlier version of IE or Windows then you need to update.

The following combinations of Internet Explorer and Windows OS version will not be able to connect after TLS 1.2 enforcement:

  • Versions lower than IE11 on Windows Vista, XP or earlier OS will not be able to connect.

  • IE7 or earlier on any Windows OS will not be able to connect.

  • IE10 on Windows 7 or 8 may be required to enable TLS 1.2 in the browser settings in order to continue to connect after TLS 1.2 enforcement. To enable TLS 1.2:

  1. Go to Tools, choose Internet Options, and then select the Advanced tab.

  2. Check TLS 1.2 and then uncheck SSL 3.0 for additional security.

  3. Click Apply, and then OK.

Google Chrome

The minimum supported version for use with Webex Meetings is Google Chrome 65. If you are on an earlier version you should update to avoid interrupted service. Google Chrome versions earlier than 33 will not be able to connect to Webex Meetings after TLS 1.2 enforcement.

Mozilla Firefox

The minimum supported version for use with Webex Meetings is Firefox 52. If you are on an earlier version you should update to avoid interrupted service. Firefox versions earlier than 27 will not be able to connect to Webex Meetings after TLS 1.2 enforcement.

Microsoft Edge

The Microsoft Edge browser is compliant with TLS 1.2 and users can continue to use it to start and join Webex meetings after Aug 03, 2018.

Java

Java version 6 and Java version 7 users must enable TLS 1.2 manually from the Java Control Panel:

  1. From the Windows Start Menu, select the Java Control Panel.

  2. Select the Advanced tab.

  3. Scroll down and select the Use TLS 1.2 box.

Java version 8 already has this setting enabled.

Android and iOS

No interruptions are expected when joining meetings with Cisco Webex Meetings for Android or iOS.

Cisco Webex Web Application

Same browser support applies if joining from the Webex Web app.

XML and URL APIs

Application calls to the Cisco Webex API must use TLS 1.2. After TLS 1.2 enforcement, applications won’t be able to connect to Webex Meetings using protocols lower than TLS 1.2.

Cisco Directory Connector

If you use Cisco Directory Connector to sync your users, you must upgrade to Cisco Directory Connector 3.0 before Cisco starts enforcing TLS 1.2 connections. After TLS 1.2 enforcement begins, Cisco Directory Connector versions earlier than 3.0 won’t work. If you don’t upgrade then the provisioning and deprovisioning of users won’t occur in Cisco Webex Teams. Cisco Directory Connector 3.0 relies on Microsoft .NET Framework 4.5 and later versions. Please also make sure your VM or Windows OS has Microsoft .NET 4.5 or later installed. To Learn more, check out https://collaborationhelp.cisco.com/article/nqvsbmq.
