Sarika, A REGISTER with no Contacts is a "Fetch" request which returns all bindings (Contacts) for the address-of-record (AOR) in the To header. The response will be 200-OK, and all registered contacts/bindings for that AOR are returned in the Contact header. If there are no bindings for that AOR, the response will not have a Contact header.
