Hello, I have the Elastix box located in a private network with my router DMZ setup to forward all the packets to the Elastix box. This means I can now access Elastix from internet. It's the first time I am setting up Elastix and I setup few Extensions 3000,3001 etc. I then tried to connect using Xlite (from the internet) but it won' connec't. The error is REGISTER 404 not found for user 3000@<ipaddres>. Is it possible to connect a SIP phone in the configuration above or only within the local network ? I did not setup endpoint configuration as the scan box only showed the local network. Is this step required to connect a phone ? Regards.
