It was unable to set Hybrid/PBX mode in Magix processor CKE 5, R5, V7. The boards allow you to switch between key and behind switch mode. I bought 9 processor from internet, 4 has this type problem, even default to factory setting. Is any jumper setting on the board needed to change.
Thanks,

on the processor there are two dip switches,both closed is permanent key mode,both open is hybryd/pbx mode.

You are right!
Thanks,
