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
