This looks like a third party register sent on the ISC interface.
AFAIK, the behavior you are seeing is normal. The original REGISTER is
not proxied: a new dialog between S-CSCF and AS is started instead (the
S-CSCF becomes the UAC). The IMPU of the user that is triggering the
third party register cans be seen in the To: header field, and the
original Contact URI info is lost.
