I've encountered two of these voice mail systems of the many that we are supporting where the customer claims that they either receive a call indicating that the system's capacity is at 80% or in extreme instances, they can't record or change greetings, take messages, etc. One that I found was definitely hacked and a number from the Philippines was entered for notification. I cleaned all of that mess up, but when I look at a memory report, it still shows no memory available. I was able to make the customers delete all of their saved messages, which made a little bit of room to allow for a greeting change, but even that was tight.
Is there a utility where I can go to dump garbage files, like error logs, etc? I was thrown to the wolves on these things with my new job and I don't have a clue.
