    Is the primary extension associated with the device itself?  Or only thru the user to the device?  I've found tkDnUsage in endusernumplanmap and applicationusernumplanmap, but I've found it nowhere else and nothing to indicate that there is a device-level primary extension.
     
    Any help will be appreciated.
     
    Thanks,
