Hello
I am trying to set up webRTC video calls from my Chrome webbrowser (Fedora) to my Chrome webbrowser (Windows 10).
There is local video input (I can see myself), but never video on the receiving side.
This is the case in both directions (so it makes no difference which peer is calling which peer). 


Both webRTC SIP peers have opus and H264 codec in their peer definition :

  Video Support: Yes
  Prim.Transp. : WS
  Allowed.Trsp : WSS
  SIP Options  : (none)
  Codecs       : (opus|h264)
  Status       : OK (75 ms)
  Useragent    : SIP.js/0.12.0
  Reg. Contact : sip:llghjqha@192.0.2.239;transport=wss
  RTP Engine   : asterisk
  Encryption   : Yes
  RTCP Mux     : Yes


  Video Support: Yes
  Prim.Transp. : WS
  Allowed.Trsp : WSS
  SIP Options  : (none)
  Codecs       : (opus|h264)
  Status       : OK (47 ms)
  Useragent    : SIP.js/0.12.0
  Reg. Contact : sip:6ltm4mqe@192.0.2.7;transport=wss
  RTP Engine   : asterisk
  Encryption   : Yes
  RTCP Mux     : Yes


In general sip.conf I have :

videosupport=yes
disallow=all
allow=alaw
allow=opus
allow=h264
When one peer makes a SIP INVITE for a video call, it is clear to me that the necessary codec information is present (this all looks fine to me) : 

(calling webRTC client)
