Using SIP in the network architecture you describe requires some
"extensions" to the protocol.  There is a solution to the situation in your
example though.  That is to use the SIP INFO method to carry ISUP messages.
See http://www.ietf.org/internet-drafts/draft-ietf-sip-info-method-03.txt
and http://www.ietf.org/internet-drafts/draft-ietf-sip-isup-mime-02.txt.
