Jay,

The principles in the tutorial hold true today, and yes, kamailio does
support WebRTC. Assuming you want your video conference to have more
that two parties, you will also need a media server in addition to Kamailio.

Kamailio does not handle the mixing, timing, etc of media to enable
multi-person video conferencing. So, you will need this being done
either by a separate media server or endpoint capable of doing this.

There are some products like Jitsi Video Bridge and FreeSWITCH that
support video conferencing "out of the box." You can combine these with
Kamailio as well to handle additional security, authentication, etc.
