As a quick Google search reveals¹, this most probably identifies as
PCI vendor ID: 127A, PCI device ID: 2013 ; data/fax PCI vendor ID: 127A, PCI device ID: 2014 ; data/fax/voice PCI vendor ID: 127A, PCI device ID: 2015 ; data/fax/voice/speakerphone
and therefore should qualify as a fax modem. The way I see it every modem should, but I'm not definitely sure about this.
