I have some sage advice¡¡
Never try to control a Cisco room device with a non-native comm port.
Original config was VC4 with CEN-IO3-4 with com 3 card. I was getting very erratic behavior. Codec would not stay initialized.
Once I was able to obtain a CP4 with a native comm port, my troubles were over.
Anyone else had this problem?
