I have a Norstar-Plus Compact ICS system model #NT7B58AA with an LS/DS card model #NT7B75GB. This sytem currently has 2.0 Expanded software w/IRAD .
The question I have is what caller id cards are compatible with this system and if I were to upgrade the software to say 4.1 or higher, would that make a difference as to card compatibility.
A little background... I was given this system by a friend who closed a business and it is being used in my house which is a rather large 150 year old home with 4 generations (thus the convenience of having such a system).
Thanks in adavnce for any help!
