As of 11am this morning (and continuing to at least 11:30am, and for all I know still going on), Vidyo is refusing all connections from the conference bridge. That is, if you dial the 800 or 650 number, you cannot join a conference. Reported already to #servicedesk, who told me to file a bug here.
This was resolved with a reboot of the system. You had left the channel by the time I joined. Investigating root cause with Vidyo.
This was a bug that is fixed in the new version of VidyoGateway. Work around is regular reboot.
