The specification doesn't explicitly state that the connection/conference
is driving a media stream to the dialog, but this is a reasonable 
However, other interpretations are also possible, because the specification
states that the connection/conference is "associated" with the dialog.
For example, connection/conference could be the one specified in 
or <dialogstart> although it doesn't drive a media stream to the dialog.

There are still no input and output properties in <dialogprepare> and 
I think that the specification should introduce these properties instead of
connectionid / conferenceid.

I agree.
