Hi Nabeel,
According to RFC3263 (Locating SIP Servers), if no proto/port
indications are found in the URI, a NAPTR lookup should be tried (to
determine the protocol). If no luck, UDP is assumed. And it proceeds
with port discovery - doing an SRV lookup .
In your case, there is no proto, proto. No NATPR either, so UDP is
assumed as default.

I think the routing URI should be "sip:mydomain.com
<http://mydomain.com>;transport=tls". Please let me know how I can
specify the URI for TLS in OpenSIPS.
I have an SRV record at my domain for TLS, but not a NAPTR record.
In the log below, OpenSIPS first looks for NAPTR record, doesn't find
it, then looks for SRV record, but it is for UDP so it fails:

Hi,
What is the complete SIP URI that OpenSIPS tries to resolve ? What
kind of query (NATPR , SRV, AAA) and the query string depends on
the RURI you have.

I'm running OpenSIPS with TLS support compiled and enabled. The
first SRV record OpenSIPS searches for when connecting is
_sip._udp. (as shown below).
It should be _sips._tcp. How can this be fixed?
