It needs to be dialable... You likely have an extension conflict as this should show up after an Import/Export... Do a full Import/Export to the node in question then examine the system logs on both to see where the conflict is and rectify it so the extension of the CRA is dialable, then it will work.
Basically, the CRA isn't seen because it wasn't imported into the system so it "knows" what it is, likely due to an extension conflict. Just because the phones are dialable, doesn't mean everything is.
