[asterisk-users] SendImage on SIP channel

[Danny Nicholas]

This may be a "left-field" .02, but it seems that you would need the JPEG
codec up on the channel to send an image.

SendImage != video.  There are features in IAX2 that are not present in any
other protocol.  One of these is the ability to send a snapshot image across
the protocol.  Video is something completely different.  For video to work
on
SIP, you must negotiate it on call setup.
