I have a Magix R4 with a 391C power supply and all MLX phones that I think is haunted...not really, but doing weird things.
Phones will die and then start to work again when you plug/unplug them. This is random - not in a specific board. Ditto with static that appears and then disappears. Plus phones will click like they do sometimes when you do a system restart; again, random with no pattern I can see. And finally, incoming callers will hear a busy signal when all lines are available (I have not witnessed this myself but have seen all the other things happen.) I have replaced the processor and a couple of boards with no improvements. Any thoughts?
