Hello Nick! I'm still learning more about Kamailio and how it works. This is being a lil bit hard to me because I don't understand too much about programming and all those "if's" and "else's", but I'll be happy to help you and provide you the information that I used to have y scenario working fine.
I spent a lot of time to have this scenario up and running in the way that I need, but here are the main documentation which I used: This link here explain how to have Registrar and Proxy in different servers. It helped me a lot to understand the message flow between the servers: http://www.kamailio.org/dokuwiki/doku.php/tutorials:openser-modular-install This here, shows how to enable the websockets in Kamailio. I think that is a good point to start: http://nil.uniza.sk/sip/kamailio/configuring-kamailio-4x-websocket Here I found a good example that shows how to have an Edge Proxy with websockets support: https://github.com/kamailio/kamailio/blob/master/examples/outbound/edge_websocket.cfg So, I got a mix of information and a lot of attempts and errors. BTW, many thanks to Daniel and Frank Carmickle that helped me a lot with my questions! If you need more help, please let me know! :-) *Bruno Emer* Mobile: +55 11 96540-0044 email: brunoe...@gmail.com <https://www.facebook.com/bruno.emer.5> <https://www.linkedin.com/profile/view?id=86461237&trk=spm_pic> <https://twitter.com/brunoemer_> <https://www.flickr.com/photos/122070309@N03/> <http://google.com/+BrunoEmer> <http://instagram.com/brunoemer_> 2014-09-24 10:52 GMT-03:00 Bruno Emer <brunoe...@gmail.com>: > Thanks again for your help, Daniel! > > Now my scenario is working! > I have two Edge Proxies and a single Registrar server pointing to a > external PostgreSQL database. > > My two users (alice and bob) are authenticated each one in a Edge Proxy > and I can start a session between then using WebSockets.
