Try testing your modem. Use this: http://www.majorgeeks.com/Passmark_Modem_Test_d326.html Install it and run the diagnostic with the phone line plugged in to the modem. Click Config first and set the test to run on the same COM port that your modem is on; usually COM2. I usually use the Local Diagnostic option (I think... It's been awhile since I've tested a dial-up modem). But you can try all three different tests... if one doesn't seem to work right, try another.... good luck!

Here's another: I've never used it, but it looks OK: http://www.majorgeeks.com/Modem_Doctor_d309.html
