[reSIProcate-users] NAPTR for TLS only

[Daniel Pocock <daniel@xxxxxxxxxxxxx>]

I'm just wondering if anyone can comment on expected and actual behavior
if there is only a NAPTR record for TLS, e.g. I have:

sip5060.net.         IN    NAPTR    10 0 "s" "SIPS+D2T" ""
_sips._tcp.sip5060.net.


and I don't have any entry for "SIP+D2U" or "SIP+D2T"

If some third party repro instance (e.g. sip-server.example.org)
receives a request from a user trying to call sip:user@xxxxxxxxxxx, with
a sip: rather than sips: URI, should it use the "SIPS+D2T" result, if no
other result is available?

Or should it ignore the NAPTR record and try to find the default SRV
record such as _sip._udp.sip5060.net ?

Should there be another NAPTR record to translate sip: to sips: using a
regex perhaps, or would such a NAPTR be a bad thing?
