Hi, an exotic case:

- For domain example.org there is a NAPTR record pointing to SIP+D2U
_sip._udp.example.org.

- But for domain example.org there is no SRV record for _sip._udp.

- And there is A record for example.org.


So if a proxy receives a request with RURI "sip:[email protected]" (no
port, no transport), and it performs NAPTR/SRV stuff, should it fail
(maybe reply 404)? or should it perform DNS A query?

Thanks.
