Thanks to all your help, you who you all are (PD Thanks!), I have made some significant progress. The next step in my PBX challenge is to find a way to connect a Voice Mail Application Module to the KSU. I need to know how the NAM interacts with the KSU. On the NAM i have 2 boards with 2 copper ports each with RJ 11 pigtails attach to the boards. I am having difficulties understanding how the voice mail is intergrated with the entire system. I was hoping someone can walk me through the process of connecting the NAM to the system. What are the RJ11 Pigtails for? I would appreciate all the help i can get. Thanks all!!!
