Supported Versions of Expressway for Hybrid Services Connectors
For a new hybrid connector host, we recommend that you register an Expressway box with the latest software release to the Webex cloud. For existing connector hosts, we support previously released versions of Expressway, with specific versions mentions in this article. You'll also receive notices in the Expressway interface when it's time to consider an upgrade. Make sure that you update the Expressway software on your connector hosts as often as possible.
Supported Versions
Hybrid Call Service on the Call Connector architecture has gone End of Life (EOL), so the service is no longer officially supported.
You must keep your Expressway-C connector host for hybrid services up to date. You can download the latest Expressway software, free of charge, from software.cisco.com.

For existing Expressway connector hosts that are already registered to the cloud, we recommend that you upgrade your Expressways as soon as possible after a new version is released, but we support as early as version X8.11, and any minor or maintenance release built on top of the supported releases. |
Upgrade Reminders
For Expressways that are at risk of being unsupported for hybrid services, you'll receive advanced notice in the Expressway interface that reminds you to upgrade to the latest version. The Expressway version your hybrid deployment is running on determines the reminder that you see; both cases are covered in the following table.

For Expressways that are one release behind the latest, you'll receive advanced notice on the Expressway that reminds you to upgrade the latest version. Connector software still automatically downloads, installs, and runs, and your deployment is still supported, but we recommend that you upgrade to the latest version at your earliest convenience.
