I am having bad luck with both the flash and hard drive voice mails. They seem to go down whenever they feel like it. If you shut the system down and turn it back on, it will work fine for days, weeks, or months (you just never know when it's going to happen again). I have talked to Comdial tech support and get different answers. One told me to edit the diskm.bat file and another told me to NEVER change it. But, they can never tell me why. I've also had them go down and not come back up. I then send them away for repair, but no one will tell me what the problem is with them. Has anyone else had problems with the voice mails? It doesn't matter if they are old or the newer ones.
