Install multiple voice modems

I have multiple modems installed, but it seems the system only recognize the first one. What should I do?

1. First, please make sure all modems are firmly pushed into the PCI slots.

2. Then make sure the correct voice modem driver is installed. For details please see: modem FAQ #5

3. Go to Windows Control Panel > Phone and modem options, then choose the modems tab. If there is only one modem listed, please click the Add… button to have the Windows OS to recognized the rest of the installed modem.

4. If you have an old computer, the PCI slot might have some problem. Try to clean it or change to a different one (if there is another one available)
