CX93010-CallerId-Monitor

CX93010 has some problems to detecting CID but by seting Country of installation and activating reporting can fix them.

1. You must set Country of Installation to B5 by AT+GCI=B5 I got it after a three weeks of investigations (It may defer in your country it can be 00 or B4 or B5 but B5 for works for most of land lines):

   

2. Then enable CID reporting by AT+VCID=1 or AT+VCID=2 as it said in manual:

   

3. And then it works flawlessly:

   

And this is the final code based on this rules:

    {
        public partial class Form1 : Form
        {
            public Form1()
            {
                InitializeComponent();
            }
    
            SerialPort sp;
            private void Connect_click(object sender, EventArgs e)
            {
                sp = new SerialPort(textEdit1.Text);
                sp.BaudRate = 11500;
                sp.NewLine = "\r\n";
    
                sp.Open();

                sp.WriteLine("AT+GCI=B5"); // can be 00 or B4 or B5
                sp.WriteLine("AT+VCID=1");
    
                sp.DataReceived += new SerialDataReceivedEventHandler((object _s, SerialDataReceivedEventArgs _e) =>

                    consoleOut.Invoke((MethodInvoker)delegate {
                        // Running on the UI thread
                        consoleOut.Text += newData+ "\r\n";
                    });
                });
            }

        }
