An sdk for Magic Jack?

Is there an SDK for Magic Jack?  (VB.NET)

If not, can someone help get me started?  I want to program my own interface ( to make VoIP calls to land lines (so the user dials by clicking a button, etc..).
Are there any free or if not, small fee software/services to help me get started?

Thanks in advance.
