When using Super Copy to copy a device, the original copied device rings fast busy until a change is made on that device and reset. Example: I have a 7941 phone with extension 1234 on it. I do a Super Copy on it and create a new 7941 with extension 5678 on it. 5678 will work fine and can make inbound and outbound calls. Extension 1234 will ring fast busy on incoming calls but can make outgoing calls. The fix is to make a change on Extension 1234 and reset the phone through CM. Simply resetting the phone (without making a change to the phone) through CM will not correct the issue. I can recreate this issue at will. I just thought I would throw the question out here before I open a TAC case.
