Hello

First of all , check your bind server that listens port 53 by netstat -nat

Secondly , check your resolv.conf that nameserver is your bindserver.

Lastly , you can check your domain with dig command

Dig @bindserverip A pcscf.kamailio-ims.org Or you can see ur server query which ip by dig pcscf.kamailio-ims.org For naptr Dig napt domain-name.org For srv Dig srv domain-name.org

Good luck.

Hello, I am trying to implement Kamailio as IMS system. I have followed tutorial linked below:

https://www.kamailio.org/wiki/tutorials/ims/installation-howto

When I try to configure my DNS, I cannot ping cscf modules on my local network, however when I'm on wireless, I can ping them.

Config:

kamailio-ims.org.dnszone

$ORIGIN kamailio-ims.org. $TTL 1W @ 1D IN SOA localhost. root.localhost. ( 2006101001 ; serial 3H ; refresh 15M ; retry 1W ; expiry 1D ) ; minimum
