    "It's worth noting that since VoIP is a digital emulation of a system
    that functions, in part, on old analog rules, it can be attacked in both
    modes. The POTS (plain old telephone system) was vulnerable to attack
    many ways, for example, through "phreaking," as in the classic story of
    the toy whistle that was packaged in boxes of Cap'n Crunch cereal that
    could emit a tone that would put the phone in operator mode, at which
    point the caller could call anywhere.

    "There also are VoIP-specific protocols, such as the ultra-important SIP
    (session initiation protocol) architecture, which can have their own
    vulnerabilities. These protocols transport over IP networks, typically
    in UDP packets, so certain classic networking vulnerabilities may come
    into play. VoIP hardware devices, too, may have their own peculiar
    vulnerabilities"


    How safe is VoIP?
