Thanks mayamatakeshi. I added flushes after each send, but still not working. Setting up packet capture now.

I am attempting to do this, but having trouble authenticating. I wanted to make sure I was not overlooking something basis in my approach. I have successfully loaded FS on a windows XP server and can register phones and make calls. Further I can talk to the server, authenticate and make calls using telnet, but when attempting to do the same via an app written in .net and using a socket, I am unable to authenticate. Running my app using a tcpSocket, I receive the "Content-Type: auth/request" upon connection of the socket, but when sending "auth password\n\n" it appears that the connection times out after about 10 seconds and I receive: "Content-Type: text/disconnect-notice" & vbLf & "Content-Length: 67". mod_event_socket is enabled in modules.conf.xml . Is there something obvious that I am missing conceptually, or should this work? Maybe the .NET component is set to buffer data before sending it. There might be some method to flush the data immediately. If this doesn't solve it. I would get a packet capture. r, takeshi
