    I had this problem where my modem (USR 5699B) would connect fine and the next time would fail to train/negotiate a speed with the same fax machine. After trouble shooting with tech support at USR, I thought maybe it’s a problem with the modem it’s self. I purchased another USR modem (5660C). This FIXED the problem and I have not had a failed connection since!

    Its possible by simply changing the modem drivers support in Windows, you corrected the issue. Here is what US Robotics has to say about different types of modems that you can buy, I always recommend Controller-Based type modems as they are the most reliable.

    Controller-based modems

    Modems are distinguished from one another by their architecture, that is, where the processing takes place: in the modem or in the PC. A hardware modem is a “Controller-based” modem, and it does all of the work. This type of modem provides the best power and performance, and it does not utilize the PC’s processing power. All three components (MCU, DPU, and DAA) are in the modem itself. It can work with many operating systems, and functionality may be upgradeable through ROM uploads.

    Controllerless or Winmodemsâ„¢

    Controllerless modems (or Winmodemsâ„¢), as the name implies, do not have an onboard Microcontroller. As a result, data compression and the generation of AT commands are performed by the PC. Since most PCs sold today run the Windows operating system, the microcontroller program is usually written specifically for Windows, hence the name “Winmodem.” They are useful in laptops, as they tend to use less power. Winmodems are usually software upgradeable.

    Softmodems

    Softmodems are, quite simply, Software Modems. All processing is done by the PC, and the “modem” is little more than an interface to plug in the phone jack. These modems require the PC to do all of the work, and they will only run in the Windows Operating System. Many PC makers put Softmodems in the PCs that they sell to consumers, as they are extremely inexpensive. They are upgradeable.
