This may just be timer synchronization issues where the first REGISTER request took some time to be resolved via DNS long enough that the timer for retransmission has already fired. OpenSBC is caching DNS records so that the next need for DNS resoltuion would be faster. OpenSBC does not support unsolicited NOTIFY. Your provider might be using NOTIFY to maintain NAT pinholes, in which case the response is not really an issue whether it's a 200 Ok or Method Not Allowed.
