This is NOT good from my point of view.

The above situation is the smallest reproducable situation that I could find.
That did not involve a lot of detail.

What I am trying to do is use call files (which have NO video just like P1 above)
and call a video phone, then call another video phone. The result is NO VIDEO.
Since the first session (call file to video phone) did not have video the second
session video phone to video phone does not either.

How can this get fixed?
