I am trying to use my modem to dial out of my office. However, if I use my phone, I need to dial a "9" first before I can dial out of my office. In this case, how to tell my modem dial a "9" first and then go to my ISP? Every time, I click on the dial up icon in Windows 95. It keeps tell me that I don't have dial tone and it stop there. How can I fix this problem?
