RFC 3263 5.
....
If, however, the sent-by field contained a domain name and no port,
the server queries for SRV records at that domain name using the
service identifier "_sips" if the Via transport is "TLS", "_sip"
otherwise, and the transport from the topmost Via header ("TLS"
implies that the transport protocol in the SRV query is TCP). The
resulting list is sorted as described in [2], and the response is
sent to the topmost element on the new list described there. If that
results in a failure, the next entry on the list is tried.
This is last processing bullet and no more comments, from there comes my
question:
If no SRV records ?
(Try domain with default port ? or generate transport error)
Any comment would be welcome.
That does appear to be a bug in RFC 3263. I assume that (in parallel
with other cases) if an SRV lookup of the domain name fails, you then
do an A/AAAA lookup.
