Video Endpoints and Cisco Spark




I’ve recently spent more time testing video endpoints with Cisco Spark (SX10, SX20, Spark Board, Spark Room Kit, DX80, etc.) with my customers and have run in to several things that I think many others probably encounter as well.

  1. Check support Spark endpoints – https://help.webex.com/docs/DOC-4205
  2. Is your endpoint running the right software version to avoid certificate validation errors when attempting to register for the first time? (To activate your room device on Cisco Spark, the device must run software version CE8.2.0 or later.) https://help.webex.com/docs/DOC-7709
    1. To upgrade the codec it’s a simple process of downloaded CE software 8.2 or higher and then logging in to the web interface of the codec to complete the manual upgrade.
  3. If you plan to use a Touch 10 with any endpoint you must pair it to the codec BEFORE you register it to Spark – https://help.webex.com/docs/DOC-11657

Before I upgraded my SX20 to CE 8.2 I was seeing errors in the logs similar to

2017-12-09T09:51:08.966-06:00 a8 appl[1796]: 762.54 Wx2Http W: HTTP(2) Error: NetworkError (Peer certificate cannot be authenticated with given CA certificates)

The basic issue is that in releases of CE software prior to 8.2 the necessary CA certificates were not installed so the certificates presented by the Cisco Spark registration system weren’t able to be validated.
