A sticker on the mounting bracket says Conexant CX-9Z-NR0134 Alatel. This particular modem is a PCI Express card, if that makes a difference. It came in an HP Pavilion m8530f preloaded with Vista. I downgraded to XP Pro and have all drivers except the modem.

Vista reported it as "PCIe Soft Data Fax Modem with SmartCP".

The ListMDM program says:
MODEM #1:
