TODO:
        We need to create a structure with the TDD stuff and malloc that
        structure when needed. We can't continue to expand the SIP_PVT with
        new variables for every possible scenario out there.

	Look at how we handle REFER. We need to do the same with 
	things like session timers and subscriptions too, things that
	are not needed in each and every in-memory instance of the
	sip_pvt.
