    Ok how about using a phone wire tester. It's a little device that you can
    get from a hardware store. It costs about $3.00 or so. It has an idiot
    light,not saying you are one, that's just what it's called, that is green
    for good line, red for crossed polarity and no light for no power. Sounds
    like to me that it's crossed polarity. Many modems won't connect when
    polarity is wrong and most phones will work.

    Sujay, If you have a tip and ring reversal, only an old rotary dial
    phone will work. I haven't seen one of those for a while. A touchtone
    phone will not work with them reversed

    You can record a log of the modem's activity which
    may give you a clue about what is happening. Look
    up "Log and view modem commands" in Help and

    Dave Smith might have something. You need to find out which COM port is
    being used. You need to change it ! This should take care of the issue. Your
    client must have been playing with the settings or something they were doing
    had changed the settings. There are several COM ports that you can try....
    when you change it try to dial out.... keep trying til you through... one of
    those port should work... ok?!

    It really depends on the modem. I've found some that just wouldn't work
    with. One customer in particular had a new line run to their computer and
    it wouldn't work with the ISP that I work at. I went out and plugged in my
    tester and told them what the problem was. After the phone guy came out and
    corrected the problem it worked fine.
    BTW it worked fine with my old 33.6 external modem on the same line. I love
    that old thing. I can plug it into any computer with a serial port and it
    will auto detect and let me check to see if there is a software problem.
