    profile: missing personal data                
                
    Hello,
  
                  
                                                                                            Some personal data are not visible to the user and have to be distributed separately via email. Users often forget those and this generates support efforts. 
  It would be very helpful if the following personal data are displayed for example at the profileapp:
  - full telephone number (main number plus extension)
  - domainname
  - prefix for fax, voicemail, conference, mobility
