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. I'm using WebRTC (JSSIP) as a client to start the calls. :-) *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_> 2014-09-23 18:07 GMT-03:00 Bruno Emer <brunoe...@gmail.com>: > Hello Guys! > > Good news about my tests here! > I found some configurations relative to Outbound proxy and I get this > working.
