Re: [Freeswitch-users] Custom Channel Variables via C#

2 Dec 2010

      Thanks, the link was very helpful

I have taken a look at the link that you provided

I assume now that I can use uuid_setvar to accomplish what I want

Assuming that the uuid is 53d37581-1f90-44bf-860a-addbc8430e3a, it seems that my code would need to change to

private void injectCdrCode_ExecuteCode(object sender, EventArgs e)
{
  try
  {
    TcpClient newClient = new TcpClient();

    newClient.Connect("127.0.0.1", 8021);

    NetworkStream tcpStream = newClient.GetStream();

    byte[] sendBytes = Encoding.ASCII.GetBytes("api uuid_setvar 53d37581-1f90-44bf-860a-addbc8430e3a myChannelVariable 12345");

    tcpStream.Write(sendBytes, 0, sendBytes.Length);

    tcpStream.Close();

    newClient.Close();
  }
  catch(Exception ex)
  {
    throw ex;
  }
}

My question now becomes, how do I go about finding out the uuid for the session ? Is that obtainable via mod_event_socket or is there another way ?

Thanks

Hi,

You can't send XML dialplan actions on the socket and expect FreeSWITCH to understand it, you must follow the event socket protocol.

See http://wiki.freeswitch.org/wiki/Event_socket for more information.

I can set a custom channel variable in my incomming dial plan like this...

<action application='set' data='MyChannelVariable=12345' />

And it shows up fine in the CDR

I am now attempting to use mod_event_socket to set a custom channel variable and have it appear in the CDR

Here is the C# code so far, the code is part of a Microsoft Speech Server application that is answering the call

private void injectCdrCode_ExecuteCode(object sender, EventArgs e)
{
  try
  {
    TcpClient newClient = new TcpClient();

    newClient.Connect("127.0.0.1", 8021);

    NetworkStream tcpStream = newClient.GetStream();

    byte[] sendBytes = Encoding.ASCII.GetBytes("<action application='set' data='MyChannelVariable=12345' />");

    tcpStream.Write(sendBytes, 0, sendBytes.Length);

    tcpStream.Close();

    newClient.Close();
  }
  catch(Exception ex)
  {
    throw ex;
  }
}

After the call is answered, the C# code seems to run fine, but I dont see the custom channel variable in the resulting CDR

I figure I am not setting it correctly

Can anyone advise on what I am doing wrong ?

Thanks

Brian
