configuring/updating a plantronics voyager legend headset is quite a pita:

  • you need windoze
  • install some software which has no startmenu-entry, does not start after install
  • does not demand admin-rights when you start the .exe by hand w/o admin-rights
  • does not show up anywhere (but task-manager) after beeing started, so you can not shut it down the normal way
  • the configuration runs via a web-interface (http://www.plantronics.com/us/support/myheadset/updater/) which then talks to the running process which listens on 0.0.0.0/[::]:8011
  • this the updater-website then runs some javascript which talks via XML with the local process and plantronics.com. in a ugly way (okay it is XML…)

Here some examples:

As that seems not to be enough we have an GET request to an statistics/tracking-interface by plantronics (URI decoded):

So what is this? Modern software-design?
