Ok, I am pretty sure I know the answer to this. However, my boss is adamant about the capabilities of this unit as sold to him. I have a UC520, it has 4 FXO ports, and 4 FXS ports. From what I understand, this unit only supports a total of 4 POTS lines coming in. Boss is telling me he was told that it supports 8, and in fact it DID have all 8 lines working at one time. Is this possible?
Yes it was me I believe, since I opened this new thread as to make things easier to search for anyone else in the future. The full SKU tells me that it's a 4FXO port model, and I will need to get the 4 port expansion card to make it 8.
