I hope this helps. I haven't figured out how to hangup AND how to capture events (dialed a busy line or fax) from the modem yet. If you do please let me know.
This works if the modem is hooked up to the server. I am having problems writing this into .NET 2.0 web page as a javascript so the modem on the client machine will dial instead.

<asp:Label ID="lblModem" runat="server" Text="Label">

<asp:TextBox ID="txtModem" runat="server">

<asp:TextBox ID="txtPhoneNumber" runat="server">

If the line was found, then make a call

// Make the call
pCall.Connect(true);
