I think that is not correct. If the request contains a contact, this mean you want to register this contact (or deregister if expires=0). If you send a request with an special contact (I think it was a *) and expires=0 this means you want to unregister all. If you send no contact header at all you just poll.
The 200 Ok response always contains a list of registered contacts. M. Rangnathan schrieb: > Here is a guess : > > expires=0 implies you want to remove a specific contact.
