Where is the UAS running that the client is communicating too?
The re-INVITE should have the same call-id, branch and to tag, so I'm
thinking the UAS will pick up the IP change which is ultimately what you
want.

I don't know SIP beyond a magazine article, but at a higher level it
sounds like you need something like a mod_conntrack_sip that would
know how to parse the SIP reinvite and tweak the proper kernel entries
accordingly.
Or you might be able to find a module that can track the DHCP
conversations similarly. That being older it's more likely to exist
and would be protocol-generic, so probably better.
Either way, it sounds like you probably need a kernel module that
understands that kind of traffic and can adjust the NAT tables.
