My video is tested against my Asterisk and softphones, by doing a  plain old
call to a Playback extension playing this video.

According to me, that's the point. I don't really mind having canreinvite
set to "yes" or "no" for now. If canreinvite is set to "no", then Asterisk
can't inject video in the ongoing session. If canreinvite is set to "yes",
then the fact that Asterisk is not in the media path should not be a problem
as it can perform a reinvitation to enter this path. So the problem remains.

Thank you for your answers.
