For incoming faxes, the fax-modem must obviously discriminate between analog voice and digital fax so that the phone rings with an incoming voice message and does not with a fax. Can I assume this capability is now present in all fax-modems, whether an external modem or an internal card?
As far as I know, the ring is indistinguishable for fax or voice. Whoever wants to know must pick up and listen to the line to know what kind of signal it is. And even after that, most faxmodems are not smart enough to know it is human voice or fax/modem signal. They just assume the other sides are its peers and talk happily along. Tim Yang
