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
