Re: [SR-Users] Need help on WebRTC with Kamailio as proxy
Kamailio is just acting as a proxy and protocol modifier so to say. It is workin with rtpengine from sipwise to handle media as evident from he logs. This architectue uses a TURN server and the browser is chrome with latest updates. The only thing whih I haven't done is enable TLS in kamailio and create certs. (which I'm not completely sure how to do).. Also, does it necessitates to have Apache ruuning https on 443 ?

Are you running a very old OpenSSL version by any chance?

Hi Rahul, Don't take me wrong, but you still have some homework to do. Apache is not a requirement for webrtc ( apart hosting the website ). The only difference between using http and https is that by default on http, most browsers will always ask for the user to confirm usage of the mic/cam. WS and WSS works with Kamailio, it's only a question of configuration ( for which there are many examples, most are broken but easily fixed, for example for https://github.com/caruizdiaz/kamailio-ws , it's only fixing the record routes to get sip2ws signaling working ). Regarding rtp, you have to use rtpengine ( master from repo, not a release, dtls broken in latest 3.7.1, fixed in 3.8 ) or something else to be able to terminate ICE/DTLS when remote endpoints don't support them ( most of SIP ua's today unfortunately ), again, read, experiment, you'll eventually get it and the most important, know how your platform works ! Start with basic browser to browser calls, without a rtp proxy, it should work almost out of the box, then you can add some functionnality to the basic scenario, and I'll be glad to point you to the right direction ! Good luck ! Le 27/01/2015 03:21, Rahul MathuR a écrit :
