Assuming you have a dial-up account with your ISP, just set up your DUN connection to use the "bluetooth modem."  Works just like your normal dial-up but slower.  But I have to admit, it has helped me a time or two out at customer locations with digital PBX lines only.

 

I wish it was that simple for me.  Yes, I do have a dial up ISP.  The computer dials the number through the cell phone but then I get this 3 tone sound, same as dialing a non working number.  I can dial the ISP number manually on the cell phone and the call  goes through.  Any thoughts on what is causing the problem with the computer generated calls?

Are you sure that you aren't adding a 1 or 9?  Or more succinctly put, that you are dialing the right number (area code?)  Check the DUN settings again and make sure they are correct.  It really sounds like an extra digit is being added.  Does your Motorola BT Phone let you see the actual number dialed in the history?  This may help point you to where you need to go.  THe very fact that you are getting the service tones back tell me your BT connection is working for you!
