We get this message on several of our endpoints and most recently I logged in and started extended logging and started a webex call. Looking at the capture I see ports UDP 5004 and 9000 in the pcap, so I'm still puzzled where and how these messages are generated. I've looked at the network requirements and been through that with out network security team I'm close to having it memorized (smile).
I know the endpoint does a diagnostics test, but what I don't know is the frequency and what part of the diagnostics test would trigger this message. If any one knows how this message is generated that would be helpful for me at least.
