[Freeswitch-users] Windows-compatible FXO PCI card?

Hello For SOHO users, getting a second, Linux-based computer just to run a small voice server is overkill, so I'm thinking of selling an application based on the Windows version of Freeswitch. Instead of the Sangoma USB connector, I'd really prefer to sell them a PCI card, because it's less messy, and there's less chance of them disconnecting the hardware. I don't know of FXO PCI cards to connect an XP/Vista host to a phone line. Does someone know of such a thing? Thank you.
