Talking to local modem from a web page.

Hello Experts,

Looking for a sollution that addresses the local modem. It should work by clicking a button in a web page (ASP) I found a sollution that should do the job at


In the following example, the pager object picks up the phone (modem), dials 212-555-5555, waits about
6 seconds (each comma is about 2 seconds), then dials 1234, and then hangs up.
A possible application would be automatically sending a message to a support technician's pager when
an emergency work-order enters the system.

dim oDialer
set oDialer = server.createobject("dialer.pager")
oDialer.dial "212-555-5555,,,1234"
set oDialer = nothing

-----End of quote---------------

A downloadable code that should be compiled is privided as well:

-------------Beginning of code-----
dim oDialer
set oDialer = server.createobject("dialer.pager")
oDialer.dial "212-555-5555,,,1234"
set oDialer = nothing

Public Sub Dial(num As String)
   On Error Resume Next
   Dim Communications 'As MSCommLib.MSComm
   Set Communications = CreateObject("MSCommLib.MSComm")
   DialString$ = "ATDT" + num + ";" + Chr$(13)
   Communications.CommPort = 3
   Communications.Settings = "300,N,8,1"
   On Error Resume Next
   Communications.PortOpen = True
   If Err Then
       MsgBox Err.Description
     ' MsgBox "COM1: not available. Change the CommPort property to another port."
      Exit Sub
   End If
   ' Flush the input buffer.
   Communications.InBufferCount = 0
   ' Dial the number.
   Communications.Output = DialString$
   ' Wait for "OK" to come back from the modem.
      dummy = DoEvents()
      ' If there is data in the buffer, then read it.
      If Communications.InBufferCount Then
         FromModem$ = FromModem$ + Communications.Input
         ' Check for "OK".
         If InStr(FromModem$, "OK") Then
            ' Notify the user to pick up the phone.
      '      MsgBox "Please pick up the phone and either press Enter or click OK"
            Exit Do
         End If
      End If

   ' Disconnect the modem.
   Communications.Output = "ATH" + Chr$(13)
   ' Close the port.
   Communications.PortOpen = False

End Sub
-------------End of code------------------------------

I am not an expert in ASP or VB.
But I know that the provided answer is server-based one and I am looking for a client-based sollution.
The sollution should use the local modem in a intranet enviorment.

My question is:

Can someone please help me by providing me with a client-based sollution?

The code does not need protection an, if posible, can be used directly in the asp site. If this is not
possible a ActiveX object on the client is no problem either.

The person that profides me me with a working code will get  the points

Why not locate the modem on the server, cos you will only need one of them.  If you locate the modem on the client you will need one for each client.

While we do'nt want to use the sollution as a pager but as a replacement for the phone. And if more then one client use this funtionality I would need a modempool connected to the server. The clients have all a standard modem installed and now they use phones so the lines are at available to. The only things we need (if this would work) are headsets.

Thanks for your response,

Why not use one of the Talk Through the internet packages?

But I think that you need to get hold of the TELAPI SDK from Microsoft.

Sorry cant follow you in this one. I 've been having a sezrch at the Microsoft site for TELAPI SDK but no results come up. In Google I find only Novell results. But I think you will need a big pipeline to support this on a network.

Voice can be squished into a very small packet size and only requires a band width of just 1K bytes per second.
