I have had to add new software to the older systems to beat this problem at more than one location. The system actually never dumps so the storage capacity continues to fill up until you can't leave any messages for anyone. You will get cut off. After uploading the new software the prompts will need to be re-recorded. I have downloaded all prompts and then uploaded them after upgrade of software, but the personal greetings all have to be re-recorded. The software update is on the resellers site. This sounds identical to the problems I've had. Chris in tech support is very good with this problem at ESI. Good Luck...
