How to get incoming phone number from modem

<p>I use mscomm to listen to all incoming phone calls, could you tell me how to get the incoming number?

<pre>
Could you show me two problems in OnComm event
private void com_OnComm(object sender, System.EventArgs e)
{
try
{
// all incomming phone will add to a list (multiline TextBox)
}
catch(Exception ex){
}
}
</pre>
<p>1. Get the phone number from incoming phone<br>
2. If the phone my modem received 5 times ring, it auto hangup (or auto reply by playing a sound to the phoner who called to me if possible).

<p>thanks.
