Hallo Vince!   
      
    VC> I am considering getting one or more phones for voip and if   
    VC> successful kill off the land line.   
      
   Check out https://www.linphone.org as they are not only opensource but have   
   runtimes available for mobile, tablet and desktop.  Also ports for OS/2,   
   Windows and Linux, although the Linux port is probably native and not really a   
   port.  ;-)   
      
   My best guess is that it is probably the best thing going in VoiP land.  Your   
   milage may vary.   
      
   Het leven is goed,
