SDK 3.x support for Savi 400 Series headsets

Hi,

    In  http://developer.plantronics.com/community/catalog/  the Savi 400 Series is shown as supported by SDK 3.x.

    When clicking on it and going to http://developer.plantronics.com/community/catalog/savi-400-series   only the Savi 440 model is shown.

    So the question is: SDK 3.x supports ALL of the models of the Savi 400 Series (410, 420, 430, 440, 445, standard and -M)  or only the specific model Savi 440  ?

Thanks in advance.
