[Freeswitch-users] ESL API command to get the status of Freeswitch

[Ramesh Kandasamy]

Thanks Anthony for the response!

I am using ESL library that comes with Freeswitch source code.
I am trying to use C# ESL APIs as below to send the 'api status' command to
the Freeswitch VM from a remote server.

            //Initializes a new instance of ESLconnection, and connects to
the host $host on the port $port, and supplies $password to freeswitch
            ESLconnection eslConnection = new ESLconnection(hostName,
"8021", password);

            if (eslConnection.Connected() != ESL_SUCCESS)
            {
                Console.WriteLine("Error connecting to FreeSwitch");
                return null;
            }

            Console.WriteLine("successful connection");

            ESLevent eslEvent = eslConnection.SendRecv("api status");
            if (eslEvent == null)
            {
                Console.WriteLine("Error sending command");
                return;
            }
            if (eslConnection.Connected() == ESL_SUCCESS)
            {
               eslEvent = eslConnection.RecvEvent();
               Console.WriteLine(eslEvent.Serialize(String.Empty));
            }

With this am able to connect successfully. But unable to see any response.
I see the same symptoms 'conference xml_list' etc.

But If I subscribe for HEARTBEAT event as below instead of 'api status'
shown above, I see the events coming at regular intervals.
            ESLevent eslEvent = eslConnection.SendRecv("event xml
HEARTBEAT");

Am I using something wrong above?

Thanks
Ramesh
