Hi Charles,
Sorry for my late reply.
I have tried that parameter but seems that for the dmq FQDN kamailio doesn't send a NAPTR query.
Even for the SRV query, the kamailio makes it without service associated(_sip._udp).

Thank you.

Best regards
José Seabra

Hello,
I have a doubt related with DMQ dns behavior, I noticed that when kamailio starts, it tries to resolve DMQ name configured on parameter notification_address as the following sequence:
  1. SRV 
  2. A
  3. AAAA

Isn't supposed kamailio  try first resolve the  NAPTR DMQ name, and then SRV?


Can you confirm you set dns_try_naptr = yes?



Cheers,
Charles
