<p>Hello,</p>
<p>if you expect that dispatcher module will list the associated ip
addresses with the hostname after a DNS SRV lookup, then this is
not available.</p>
<p>Dispatcher module will still use the single hostname to set r-uri
(or dst uri) and then TM module does the lookup before sending,
inside t_relay(). Also, irc, the keepalive is sent only to the
first ip resolved for a hostname.</p>
<p>If you want to relay on DNS SRV for loadbalancing, you don't need
dispatcher at all, everything is done transparently for
configuration file by tm and core.</p>
<p>Maybe you can detail a bit more what you want to achieve with
dispatcher on this topic and we can think of alternatives,</p>
<p>Cheers,<br>
Daniel<br>

<div>Unfortunately with kamailio 4.4.4, dispatcher module and
your suggestions, I still don't see the SRV record picked up
(at least using the kamcmd dispatcher.list command).

<div>I didn't try the LCR module yet, I want to be sure first
that dispatcher is not able to handle SRV first</div>

<div dir="ltr">Hello Guys!
<div><br>
</div>
<div>I'd like to be able to use SRV
records inside dispatcher groups, so
I can automatise the discovery of
new backends on my network using DNS</div>
<div><br>
</div>
<div>I've tried with the following
formats into the dispatcher.list
file:</div>
<div><br>
</div>
<div>$group
_sip._udp.sip-voice_backends<br>
</div>
<div>$group sip-voice_backends<br>
</div>
<div><br>
</div>
<div>and none looks to be working,
running the kamailio_ctl
dispatcher.list won't show me the
group set with SRV records. ( I also
try NAPTR records, with no luck as
well.)</div>
<div><br>
</div>
<div>* Does the dispatcher module
support SRV or NAPTR records? (maybe
my format is not correct) <br>
</div>
<div>* If not, do you have any other
idea on what I could do to achieve
what I'd like to do?</div>
<div><br>
</div>
<div>Thanks</div>
