This is news to me. What book?
RFC3959 defines the early-session content-disposition, for purposes of
negotiating an early media session prior to answer that is distinct from
the eventual session. In principle this can result in two SDP body parts
in the same sip message. But I have never heard of this RFC having been
implemented.
