I've verified with multiple accounts - we are currently seeing login/registration errors from the Jabber Video client (4.6 for Mac, and 9.3.5 for iPad).
The client responds with "Login failed due to registration error."
I suspect this was for the free Cisco Jabber Video beta service.
Login issue has been resolved.
Thanks Jason - You're right, this is for free Jabber, thanks for checking and clarifying.
Unfortunately, it still appears to be an issue from my end. Same error message.
Thanks - Craig
