Ok so I am new here, but hope to become a reliable member. I am also new to phones. I'm generally a network guy, but I got a trial by fire when my phone vendor backed out on me. So I have a CICS 7 system with 22 handsets. The customer moved locations and expanded. I could only get 13 of the original internal dns up and running. I assumed it was something I didn't know about the wiring and purchased an 8port expansion card hoping that would fix the issue. Everything looks right on the 66 block but when I tone and punch the lines the phones do nothing. I'm doing exactly as I did with the original 13 lines and have no idea what to do. Is there some setting to turn on additional internal dns?
