The reason that the Call-Id's on successive registrations are the same is so that the registrar can update the previous registration's record rather than creating a new one. I have seen some instances where UAs generated new Call-Id's for each registration, and the registrar's database did get cluttered with old registrations (which it kept around for an hour or so after they expired).
