Trying to program a station number into a 2400 IPX. ASDT gives the error message: Station Cannot be Assigned. Double Assignment. DSTN gives the same error message. The station does not appear in the Lens print out. I ran the command to show all appearances of the phone number on any station. I believe this was LMLA4 or something similar. It pulls up four stations but this number is not actually programmed on any of them. I checked ASPA but the digits I am using for the numbers are only assigned for stations in this building. No routes or anything like that are using them.
