Hi -
From the Unity 4.2(1) release notes - Changed Functionality section, page 31, "The hunt order for MWI voice messaging ports has changed when port memory is enabled. If the MWI device is not yet assigned to a specific MWI port, Cisco Unity will hunt for the next available MWI port in an ascending round-robin order. In earlier versions, Cisco Unity hunted for the next available MWI port in descending order beginning with the last MWI port."
