Yeah. Did that once or twice for the random alarms. Which didn't seem to clear that problem although it did go away from what my friend tells me.
It just started doing the loss of changes fairly recently. But that may have just shown up since someone put the power cord on the surge only side of the UPS... ?! Just found that out today.
So it may have had this issue all along.

The DND issue. CCBS and CCNA should be on then for the DND to actually block the caller along with DNDO being on?
