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 Alessio

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).

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?
