Hi Kenny,
actually is a routing problem. the NOTIFY hits the lookup("location")
and because there is no username in RURI, "404" is returned.
these requests are only ping from the phone, so your proxy should just
reply them. Do something like this: if it's notify for my domain and
there is no username, send stateless 200 OK.
regards,
bogdan
