[SR-Users] switch kamailio to domain

Hello Sirs, The RLS module is eating my life. I just managed to make it work 2 months ago and now is not working anymore after I tried to put the kamailio under domain (until now it was simple ip). I don't understand why is not working but I saw a big difference that I don't understand: My environment: - the domain "domain.com" is pointing to the web server - kamailio is hosted under sip.domain.com - DNS has domain.com A record for web server's ip, sip.domain.com A record for kamailio's ip and SRV record for _sip._tcp.domain.com poting to sip.domain.dom Problem: kamailio presence is not working anymore and I think, the error is: grep_sock_info - checking if host==us: 11==14 && [domain.com] == [xx.xx.xx.xx witch is the sip.domain.com IP] If, I change domain.com in DNS to point on the same ip as sip.domain.com RLS is working. This, I can't understand. Can anyone explain me why is not working using this configuration? Also, the RLS is working if i change my domain to be sip.domain.com (ex: sip:user@sip.domain.com). Thank you. Best regards, Mihai M
