I have an SX-200 bay off a 3300. One of the bays, the analog phones on it stop audibly ringing after a couple rings.
I have tried changing COS on phones on the bay, I have swapped working ONS cards, I have tried 3 different power supplies.
- I have not (recently) replaced the bay control card in the bay, I have not tried swapping out the cabinet of the bay.
The bay itself does have a glitch where it continually indicates there is an incorrect card installed:
"No card should be at location 05 01 07 incorrect card installed = 12 Port ONS" <- it has been saying this for about a year however, today after swapping power supplies it has decided the imaginary card isn't 5/1/8 anymore but is now 5/1/7.
The bay itself has 6x ONS cards in it.
I'm thinking of going back to the office for another cabinet.
I'd appreciate any of your guesses.
