Say you have 3 phones. ceo phone, sec1 phone and sec2 phone.
if ceophone is in use, can sec1 or sec2 phones see that ceophone is in use? Like how you had 3 phone lines and all you had to do was look to see which phone line was in use.
If the answer is yes, what's the technical term for that because I am not having any luck trying to setup an obi to do this and I really need to read up on this part.
