That's right. They only work on IP Office. They're 4600 phones but for whatever reason at some point in time Avaya was pushing 1600/9600 on the big systems and was dumping the old inventory as 5600 models for IPO only. At least that's what I think the story was. Anyway, they'll never work on your system.

54xx is the IPO version of 24xx and 56xx is the IPO version of 46xx.

I think the 5-series were cheaper than their CM counterpart and that's why they don't work.
