Inter-Tel is always a little excentric on their cabling. With the Axxess it's needing a 2 pair cord for a one pair connection. :bang: They chose to us the orange pair to power the phone and leave out the blue pair. The only advantage to that is being able to use either a direct trunk or the station line at any jack in the house if you choose to wire it that way. Sorry, that was a side rant. Back to your issue.
On the Premier you have to purposely wire a pair backwards. What that means is that somewhere along the way, you have to flip that pair and connect the w/b to where the b/w goes and vice versa. Some prefer to do it at the jack, others at the station block. I often did it at the jacks so that the station blocks were consistent, but Merritt pointed out that he prefers to do it at the station block so he can test the phones right there using a mod-tap.
Here's a good thread for you that talks about it.
