Prevent modems rather than detect them (Was: tool for detect modems in a lan)

    Inspired by the previous thread, I am asking myself (but my experience of
    telephony is way too outdated to answer my own question...): do "modern"
    (whatever that means) private exchanges have a feature to distinguish between
    true voice calls/fax AND data calls? If so, one could just configure them to
    block data calls whether inward or outward.

    Another way to prevention would be to provide non-standard telephone lines to
    the desktops. I once worked for a company where the extensions where provided
    with digiltal lines that where proprietary. No ISDN TAs and no analog modems
    would work.

    The other side of the coin is of course... money. Non standard telephone
    terminals are probably going to be more expensive than standard ones, but you
    may end up spending less money than chasing modems throughout a large
    organization and with more peace of mind that your company security policies
    are enforced (at least on this particular modem issue).
