Or you could be lenient. Because the port is zero, the PTs don't matter.
So you can treat it as a valid offer with a zero port.
Then, as I mentioned earlier, you still need to decide what you want to
do. You can accept the call and see what happens, or you can reject it,
probably with a 488 or 606.
