You can configure a Cisco Webex board, room, or desk device running RoomOS to use a Proxy server for HTTPS and WebSocket traffic.

You can add your Proxy Server details manually or by using Auto Discovery. Auto Discovery uses a URL to locate a configuration file containing the relevant Proxy Server details.

RoomOS supports the following types of authentication:

  • None

  • Basic

  • Digest


Proxy server support is only for HTTP(S) signalling traffic. Media traffic (UDP/TCP/TLS) still needs direct access to the internet. For more, see Network Requirements for Cisco Webex Services.

Manual Configuration

If your device is new or has been reset:

  • Room or desk device: Choose the Cisco Webex call service in the First Time Setup Wizard. On the registration screen, select Proxy options.
