<tt>Hi Nabeel,</tt><tt><br>
</tt><tt><br>
</tt><tt>According to RFC3263 (</tt><tt>Locating SIP Servers</tt><tt>),
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
.<br>
<br>
In your case, there is no proto, proto. No NATPR either, so UDP is
assumed as default.<br>

Please let me know how I can specify the URI for TLS in

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:</p>

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.<br>
<br>
