services within your LAN via the domain name without needing to know your Dynamic public IP Address.
After setting DDNS, IP PBX phone services can be accessed from remote site via the domain name which your
DDNS provider supplied you. Also remote management is possible, even without a static public IP.
IPPBX system supports the following DDNS service providers:
 Easy DDNS
 PlanetDDNS.com/
 http://dyndns.org/
 http://www.noip.com/
 http://www.zoneedit.com/
 http://www.oray.com/
 http://www.3322.net
 http://freedns.afraid.org/
Sign up to one of these DDNS service providers’ website and subscribe a dynamic domain name. Once you have
your account details, register it here and you DDNS domain will work with the IPPBX system.
After completing the above, please configure port forwarding on your router/firewall, then you’ll be able to
remote access IPPBX services from the internet using this dynamic domain. For example, you can port forward
port number 443 and then you can access the IPPBX web interface by using the URL:
