anyone know anything about land line business phones?

We have a pretty simple setup, 4 phones in our office. 3 lines through an old phone system. I am pretty clueless about all this, but we need to replace 1 or 2 phones. If I were to buy a simple 3 line phone, theoretically should I just be able to plug in and away I go? No voice mail, call display or anything like that, just the 3 lines.



We have old Panasonic's right now and was thinking of just getting a new 3 line phone:
