We are busy to develop an app to let users call eachother using webRTC. On this moment we have audio working, but video not. Now I hear that a proxy server can be the solution for this problem. But it seems a bit illogical, because what are the benefits to place a proxy server before the sip server Asterisk? Why should the video flow with a proxy but not without a proxy?
I heard of kamailio as a proxy, registrar server before asterisk. But I can't find any information about the benefits and why video stream will flow.
I hope someone can point me in some kind of direction to figure this out.
Thanks in advance.
