Re: [Freeswitch-users] event socket

25 Oct 2011

      Sorry still no progress, code as follows

               if (eventHandle.getType() == "CHANNEL_STATE" && eventHandle.GetHeader("Answer-State") == "ringing")
                {
                    eslConnection.Execute("answer", null, CallID);
                }
Thank you,

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 receiving events. However when I try to execute "answer" application it's 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 advise

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: http://wiki.freeswitch.org/wiki/Event_Socket_Outbound#Examples

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,
