Kamailio IMS Implementation DNS Problem - sr-users

8 Jan 2019

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
