I support an office that has been experiencing a great deal of static on all analog phones in their Magix system. They have (2) 016 TRR cards that are both at issue. All MLX cards\extensions are fine.
I sent them (2) replacement 016 TRR cards to try and both had the same results. There aren't any power cables draped over it or anything that is an obvious source of noise interference.
At one point the customers were complaining of a VERY annoying pulsing static sound, but I think that has gone away with a reboot and its back to just the normal background static that is annoying but mostly just to those who are complainers.
They are in another state, and I'm just helping support our local IT technician there on the front lines.... so I don't have a whole lot of infomation. I just figured I'd post a comment here in hopes that someone would have other suggestions.
