Video over Asterisk using IAX

Hello to everyone,
I’m trying to send an audio+video stream from an asterisk server to another one using IAX…
I have seen in examples that in configuration files (both iax.conf and sip.conf) I’ve to add the following lines:

. videosupport = yes . . allow = h261 allow = h263 . .

The audio work well with dial(console/dsp) sintax in extension.conf.

How can I send also the video (that comes from /dev/video device) ???

:wink: Thanks a lot for any help !!! :wink:
