asterisk users - Apr 2018 - Asterisk behind NAT Early Media Video

My understanding based on Wireshark analysis is that the signaling works
(also the recipent phone is displaying the video frame before accepting the
call), also the calling phone send video (i see that also via Wireshark)
but the recipent phone doesn't get any video from the Asterisk before the
call.

wohoo, so if I unterstand it correctly with that patch early media video
works over the Asterisk server? In other words the Asterisk server get's
able to (process/)forward the early media video stream with that patch?
