The originate from the ARI is working much better, I can now add RTSP-SIP channel with video to the bridge. I have made a Python script here: https://pastebin.com/iyWPdNJp There is one last problem though, it seems that the video does not connect right away, it is only a black screen. If I press "hold" on then off with videophone or if I stop/start video (also from videophone) then the video starts working. I think the key here is a re-INVITE. I looked at the SIP packets and the initial INVITE looks okay, so I am thinking something is not quite right with Asterisk and it needs a little kick? Here are the packets showing first and second INVITE: https://pastebin.com/xKwNb1nt I have found this here, maybe related? https://community.asterisk.org/t/ari-add-channels-to-a-bridge-with-video-source/88959 Is there some way to execute re-INVITE from ARI? Thanks, Ryan
