I have an 8x24 , Centrex software , ports 101 - 112 equipped and working . I tried to add 8 new phones but they would never sync up , just flash forever . I can get on ports 101 - 112 with one of my new phones and it will sync up , but when I try 113 - 124 it will not sync up . I have replaced the 25 pr cable and 66 block , rebooted system , disabled and enabled ports in question , set relocation is off , still no change . Everything else on this system works fine . Am I doing something wrong or do I just have a bad KSU ?
