Unfortunately the answer is facetious, if you have a existing registration i.e. the To header and one of the Contact headers match it's a renewal, otherwise it's a new registration. Call-ID and CSeq are really just for transaction matching. If you want to renew a registration as I think you mean, you need a wildcard registration with an Expires of zero first and then register the Contact(s) you want to use.
