Some SIP systems will not accept INVITEs from phones that are not registered with the system. This is not a requirement of SIP, but it appears that your system enforces this requirement. In regard to the specific "487" response, its purpose is to report that the processing of a request was terminated by a CANCEL. So it appears that that response code is being used incorrectly here.
