Rickman, Thanks for the reponse. Slot 1 has ESIE-8 (looks like a piggyback card on it also), slot 2 is empty, slot 3 (B4-U10 ETU), slot 4 (NEC 180365-001, DTI U40).Slot 5,6,&7 are empty. Slot 8 Elite Mail (which will not be used)
I just want to be able to add 2 C.O. lines into the system, where they can make and receive calls
