Indirt. Well my offiice is going to talk to CETEK. In the mean time here is the story. Duplex Ultrons have been ending in the overhead for at least since 2012 according to onsite callback charts. Previous service companies have changed all the boards minus the backplane. The issue got much worse because one car has been turned off for a cab refurb. Since I took the non zoning floors off under the com tables menu at the least tge car doesn't zone to the top and then end up on the final when it flakes. Now it stays at the last call and then will will intermittantly act like it is taking a call to a above the top floor and go into nts and then reset. Any ideas I will gladly check into. Thanks Mike
