NOTIFY's are in-dialog requests. Your From and To header are missing the required tags (and look a bit suspicious by themselves too because of the double <>). The grandstream probably can't match the NOTIFY to the correct subscription and follows a code path that for some reason decides to answer 415 instead of a 481.
