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 On 26/01/2017 11:34, Casco, Alessio wrote: > 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 > > On Wed, Jan 25, 2017 at 8:06 PM, Jeremy Gadd <jeremyg...@gmail.com > <mailto:jeremyg...@gmail.com>> wrote: > > 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). > > On Wed, Jan 25, 2017 at 1:05 PM, Jeremy Gadd <jeremyg...@gmail.com > <mailto:jeremyg...@gmail.com>> wrote: > > Put the hostname in dispatcher (no port) and enable these: > > > On Wed, Jan 25, 2017 at 9:30 AM, Casco, Alessio > <alessio.ca...@nexmo.com <mailto:alessio.ca...@nexmo.com>> wrote: > > 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.
