Can't loggin

Hello, I just installed the Trixbox (latter Version) and I follow all the instructions published about the subject. The problem is that I create a extension (just for testing) then I try to use X-lite to connect and it says 404 - Not found. Then I try to use a Ovislik Phone 1000S and I have the same problem. I already check the network and I have the firewall disconnected. Can someone help me? I cannot find any help and I’m trying for too long. Thanks in advance.
