Damn the Fax Machines

In the modern world of communication, why do people still uses modems and fax machines??? I been trying to get modems and fax machines to work over your VoIP system over fiber…. and it sucks!!!…. what I am doing is just not natural. I just don’t think you suppose to convert a digital signal to an analog signal then to another digitial signal and then send it off. It just seems wrong.
