Hello, I want add more Digital Phones to my IP OFFICE 500 v2, I've seen this card on ebay http://goo.gl/n4zGLR

is this compatible and could support Avaya 1408 Phones?
I need buy licences or something or just Plug and Play?

That card is for Nortel TDM phones only, not the 1400 series that you are asking about. You want 700417330. Yes, it is plug and play. Power off, insert card, power up, and you have 9 new extension and users.
