I am trying to configure a CP8841 in call manager 12.5. As soon as I save the configuration, the config rejects. If I delete the new device config to start over and instead do a copy from a same model that is registered, I still get rejected on the copied device. The MAC first character is D and, for no other reason than to see if it makes any difference, I changed that first character to A, saved, then B, saved, etc.. Rejected status clears if I use any other A-F character besides D.
Can someone tell me what this is telling me is wrong?
