Re: [MEDIACTRL] Weird stuff in RFC 5552

VXML2 does define a si (screening indicator) property in each element in
the session.connection.redirect. But you are correct that RFC4244 makes
no reference to screening indicator at all for Histroy-Info header so
our implementation ends up always setting it to undefined.
