Hello,
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.
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.
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.
Maybe you can detail a bit more what you want to achieve with dispatcher
on this topic and we can think of alternatives,
Cheers,
Daniel

Thanks for your help,
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).
I didn't try the LCR module yet, I want to be sure first that
dispatcher is not able to handle SRV first
Thanks

Holy cow, sorry about that!
Put the hostname in dispatcher (no port or _sip._udp) and enable
these:
use_dns_cache=on
use_dns_failover=on
dns_srv_lb=on
That's how I got it working (using the LCR module).

Hello Guys!
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
I've tried with the following formats into the
dispatcher.list file:
$group _sip._udp.sip-voice_backends
$group sip-voice_backends
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.)
* Does the dispatcher module support SRV or NAPTR records?
(maybe my format is not correct)
* If not, do you have any other idea on what I could do to
achieve what I'd like to do?
Thanks
Alessio
