I don't think StingRay can do anything with IPSec.

IPSec is only secure if it is end-to-end. Clearly SOME part of calling isn't end-to-end. IPSec is only secure from man-in-the-middle attacks if you have some robust authentication of the endpoints. Setting up a reliable distribution system for authenticators isn't easy.
