[Freeswitch-users] Possible to communicate with FS using event_socket without ESL?

Thanks for the clarification.  I too suspect something in my communications.
Just wanted to make sure I was not missing something. Will move my
communication app to a separate machine from the FS server and run
Wireshark.  Thanks for recommendation.

Without the use of the ESL *protocol* - no. Without the use of the supplied
ESL *libraries* - correct.

You're along the right lines on implementing your own protocol. If you can
connect and authenticate via telnet from the same computer you're trying
your app from then there should be no problem with FS.

The fact you say it takes 10s for FS to respond indicates you're not sending
the auth line. You should get either a success or failure message straight
away in reply to that. So it sounds like the auth isn't getting sent at all.

Try using Wireshark to view what's going over the network to check it's what
you expect.

Am I correct in assuming that an app can talk directly to FS using

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
