title: Bluetooth communication from PC to mobile phone, use laptop speaker and mic during voice call
body: <p>I am using 32feet.net library for connecting with Bluetooth mobile phone.
  I have successfully discovered devices, successfully paired with device.
  I have successfully made a call using AT command with the help of 
  <a href="https://stackoverflow.com/questions/5960208/bluetooth-dial-with-32feet-net-and-c-sharp">Bluetooth dial with 32feet.net and c#</a></p>
  
  <p>I want to use the speaker and mic of laptop during the voice call going on the mobile phone.</p>
  
  <p>My C# code for dialing a call is </p>
  
  <pre><code>BluetoothEndPoint bep = new BluetoothEndPoint(phone.DeviceAddress,BluetoothService.Handsfree);
  
  cli = new BluetoothClient();
  
  cli.Connect(bep);
  peerStream = cli.GetStream();
  peerStream = Listofdevices.cli.GetStream();
  String dialCmd4 = "ATD"+txtdialer.Text+";\r\n";
  Byte[] dcB = System.Text.Encoding.ASCII.GetBytes(dialCmd4);
  Listofdevices.peerStream.Write(dcB, 0, dcB.Length);
  
  Byte[] sRes = new Byte[200];
  peerStream.Read(sRes, 0, 199);
  </code></pre>
  
  <p>How can I use my speaker and mic of laptop for communication on the call?</p>
