Hi All,<br>
<br>
I am experiencing an issue when i try to contact <a class="moz-txt-link-abbreviated" href="mailto:xy@cisco.com">xy@cisco.com</a>.<br>
I found that kamailio/sip-router can't resolve by default resolving
way a TCP + SRV records from domain cisco.com.<br>
<br>
e.g. cisco.com<br>
<blockquote><tt>misi@alma:~$ host -t NAPTR cisco.com</tt><br>
<tt>cisco.com has no NAPTR record</tt><br>
<tt>misi@alma:~$ host -t SRV _sip._udp.cisco.com</tt><br>
<tt>Host _sip._udp.cisco.com not found: 3(NXDOMAIN)</tt><br>
<tt>misi@alma:~$ host -t SRV _sip._tcp.cisco.com</tt><br>
<tt>_sip._tcp.cisco.com has SRV record 1 0 5060 vcsgw.cisco.com.</tt><br>
<tt>misi@alma:~$ host -t SRV _sips._tcp.cisco.com</tt><br>
<tt>_sips._tcp.cisco.com has SRV record 1 0 5061 vcsgw.cisco.com.</tt><br>
</blockquote>
<br>
I can't call <a class="moz-txt-link-abbreviated" href="mailto:xy@cisco.com">xy@cisco.com</a> because it does not exists an NAPTR record
in domain cisco.com, <br>
and furthermore no SRV with udp. <br>
<br>
But it exists sip+tcp record <br>
and also exists an secure sip SRV, so sips+tcp record!<br>
<br>
I read rfc3263 <br>
I find kamailio dns resolver is not working as it should according
RFC3263.<br>
<br>
<a class="moz-txt-link-freetext" href="http://tools.ietf.org/html/rfc3263">http://tools.ietf.org/html/rfc3263</a><br>
<blockquote><u>If no NAPTR records are found, the client constructs
SRV queries for those transport protocols it supports, and does
a query for each.</u><br>
</blockquote>
<br>
So kamailio should query all (udp, tcp, tls, sctp whatever)
protocols.<br>
<br>
Can anyone help/guide me to create a fix to this issue? <br>
My plan is to create a patch to kamailio resolver, to correct and
behave according RFC3263.<br>
<br>
Any help or guidance appreciated!<br>
<br>
Thanks,<br>
Misi<br>
