In that case an identification is not needed. Identification is required only when the message returns from the AS, as in to resume IFC matching. Also, I would recommend that you send that "1st" message from the AS to the S-CSCF, but that you always you normal SIP loose routing when originating requests from the AS towards an IMS core. Search our lists for details on how to send initial requests from the AS towards the core network in either origination or termination modes.
