Hi, I don't understand it. As I said, the symbol "_" is *not* a valid
symbol in a domain name, so for sure "_sip._udp.kamailio.org" should
not be considered as a whole domain (if so, it should be discarded as
invalid domain).

I will do some network traces and inspect what the DNS server replies.

Regards.
