I apologize already for raising this question, but does cabling not matter when coming out of your phone going into a handset or headset? I know there is a difference between a phone jack and a ethernet jack, but is there a difference in the size of the end of a RJ-11 vs. RJ-22? One of my collegues is looking at getting a system so that he can interview people on air and go through his sound board. The system that he is looking at has RJ-22 jacks on the front, but I was really of the opinion that we have RJ-11 jacks on our phones. Am I just really confused or am I correct that you cannot use an RJ-22 cable where a RJ-11 goes?
