It doesn't *need* to, but in normal cases it would be expected.
The response to the register request is the set of contacts that are
currently registered at the time the response is generated. Assuming you
supplied a contact in the register request, with a non-zero expiration
time, then you would expect that the response would contain that
contact. If it *doesn't* contain the contact, then you must presume that
you are not registered.
