    AFAIK this phone does not provide full XML services support per the SDK.  It may provide it's own flavor - probably for built-in services/features.

    The new SPA 500 series claim to support XML applications:

    But the documentation withing the SDK do no mention them as the supported phones. We have customers who are running SPA phones with Broadsoft IP PBX and want our applications ported to support those phones. 
     
    Do these phones support XML applications? If so, even when using a 3rd party IP PBX (no JTAPI involved, just data XML apps)?
     
    Thanks
