[asterisk-users] Asterisk behind NAT Early Media Video

[Benjamin Marty]

I just noticed, the calling device isn't even sending the early media video
stream. It just sends an early media audio stream. Is there propably a
change in the signaling needed?

(On another P2P SIP Server the early media video works.)
