Yes, I think BYE is only for terminating the dialogs created by INVITE as per RFC 3261. Returning 481 Transaction doesn't exist is appropriate one

As we know, when a new SUBSCRIBE occurs, it creates a dialog. But what should one do when a BYE is received on a SUBSCRIBE dialog? I don't think "405 Method Not Allowed" is right but maybe "481"? I can't believe that BYE should clear the dialog because, IMO, BYE is only valid for INVITE-created dialogs.
