I have a customer with a Norstar 824 system & Startalk voicemail. I went onsite around a week ago and the entire system was reset back to factory settings ... DNs changed, phone templates changed, etc. I reprogrammed the system to get it back like it was before (the Startalk settings were correct). This morning I got another call, and the system was reset again. I think they may have lost power over the weekend, but I don't understand why the system is not saving the settings. The biggest pain is that they cannot even use it until I reprogram it b/c they have a T1 and the default settings for the lines are rotary dial (which is not supported).

Any help on this issue would be greatly appreciated.
