[Freeswitch-users] event socket

[Hynek Cihlar]

You also have to provide the UUID of the channel, so freeswitch knows which
one to answer.

Hi,



Thanks for the reply. Yes my application is listening on the port and I’m

not working. I’m trying to execute “answer” application when I receive
“CHANNEL_CREATE” event on inbound calls. Please see code below. Could you

Please confirm: are you sending the call to the "socket" application in your
dialplan? If so, then your ESL app needs to be listening on the TCP port
specified. See the examples here:

Hi,



I’m trying to build an IVR application around freeswtich. I’m using
freeswitch event socket in C#. I’m intercepting inbound calls in the dial
plan and sending them to my application via outbound socket. Could someone
please explain how to execute “answer” application through event socket.



Eg – I’m sending the command as below and it’s not working.



ESLConnection eslConnection = new ESLConnection(server, port, password)

ESLEvent eventHandle = eslConnection.SendRecv(“event plain ALL”);



eventHandle = eslConnection.RecvEvent();

string uniqueCallID = evenHandle.GetHeader(“Unique-ID”);



*eslConnection.Execute(“answer”, string.Empty, UniqueCallID);*





I believe I’m doing something wrong as I can’t find required information.
Could someone please let me know where to find more information about
freeswitch event socket in .Net. (Google not giving me required information)



Thank you,
