im haivng TP Link 1043ND ver1.6, klseet website stated ver1.8, my question is ver1.6 can use the firmware? does it matter?

KLseet's website quoted a user with ver1.6 reported the firmware is working fine.
So it should be no problem

On the phone number issue, u can choose to keep your old number, but Unifi will still give you a new number, no more using copper line.
However, to use the new number with your alarm system is still workable. You must ask the phone line contractor to link the new line to your existing phone line in your house. This is not 100% workable though, depending on how ur house line is connected at the DB (Distribution Box) and also where unifi cables are coming in.
On a side note, any Unifi users playing Black Ops on PS3? Do you ever get 4 bar for your connection? i am always stuck at 3 bars while every other players are 4 bars. Always die before i can shoot.
