Hi, RFC 3261 says:
21.4.14 416 Unsupported URI Scheme
The server cannot process the request because the scheme of the URI
in the Request-URI is unknown to the server
But imagine these requests arriving to a proxy which just can talk SIP
over UDP/TCP (and TLS over TCP):
a) INVITE sips:[email protected];transport=udp
(note that transport=udp is not valid por sips scheme).
b) INVITE sips:[email protected];transport=sctp
(note that proxy does not speak SCTP neither SCTP over TLS)
c) INVITE sips:[email protected];transport=tcp
Route: <sips:other-proxy.org;transport=sctp>
(note that proxy does not speak SCTP neither SCTP over TLS)
d) INVITE sip:[email protected]
Route: <http://google.com>
(note the ugly HTTP URI in Route)
Which should be the proxy rejection response in each case?
Thanks a lot.
