A request should only have a To tag if it is an in-dialog request. REGISTER is not part of a dialog. A REGISTER request never has a To tag.

REGISTER-----------------------------> with Expires 0 and Contact * Is it ok for this de-REGISTER request not to have the 'To' tag as received in the 200 ok response?
