Thanks a lot TJ, I really appreciate your reply. The client sent me a picture of the CPU card and I can see a black round plug with 8 holes in it. What kind of cable would I need to connect between the MOH unit which has a standard RCA audio output jack and the MOH port on this phone system? Do you also know if the MOH feature comes enabled by default on this phone system?

Thanks in advance for your help.
