You can if it the volume is interfering with your own service, I
believe (though IANAL, either) -- see this text from
http://www4.law.cornell.edu/uscode/18/2511.html

        It shall not be unlawful under this chapter for an operator of
        a switchboard, or an officer, employee, or agent of a provider
        of wire or electronic communication service, whose facilities
        are used in the transmission of a wire or electronic
        communication, to intercept, disclose, or use that
        communication in the normal course of his employment while
        engaged in any activity which is a necessary incident to the
        rendition of his service or to the protection of the rights or
        property of the provider of that service, except that a
        provider of wire communication service to the public shall not
        utilize service observing or random monitoring except for
        mechanical or service quality control checks. 

Note carefully that the second part applies to a "provider of wire
communication service", which is a phone company, not an ISP -- ISPs
are providers of "electronic communication service".  (Just to make
life fun -- if you're a VoIP *provider*, you probably fall under both
sections, but if you're just carrying VoIP traffic I don't think you
are).
