If you are running anything less than 8.6.1 on your UC box, check your flash storage usage and upgrade before you run out of space.

I got hit with this and lost all of our voicemails

The scary part of this is how many of these boxes are installed in small businesses without any sort of knowledgeable IT staff on hand. Hiring outside help to fix a busted box and upgrade would be quite costly. How many of them regularly back up their voice mails too? Probably near zero.

This one bit me as I was walking out of the office for Christmas vacation. I literally had my hand on the door when I heard "Hey I cannot get into my voicemail"

8.5 hours later the entire voicemail/auto attendant system had been rebuild from scratch as none of the backups would take with the required upgrade of the software. Needless to say I was not a happy camper.

Did not know about this bug though. I thought it was just a quirk with all the changes going on. Not that it makes me feel any better.

Thanks for the link.
