I checked with the seller and it was new, unopened, but older (5 years or so). I have a 6 conductor phone cable, but it’s longer than the original. 10ft vs 2ft stock cable. Would that work?

That 1% is probably gonna bite me.. ;-) The only way to know is to buy another one, put a tape cover over the AIU OUT, and see if it works.
