right you can reply 484 in your dp at any time
<action application="respond" data="484 Address Incomplete"/>

then it should try again.

The bit i can't remember is if we committed a certain 1 line patch that
makes sofia parse the next invite to the same call properly, the patch was
to the sofia lib itself so test it and see.  I may need to dig up the answer
again from the sofia dev.
