To access VOSS12’s VoIP servcie from external, the VOSS12 should have
public IP address. So if a company has enough public IP address, can assing a
public IP address on VOSS12 according to the above instruction. However, a
company uses NAT for using DHCP, then use DDNS to assign a Domain
Name as a public IP address on VOSS12.Assigned IP addresses of IP routers
can be changed if a service provider provides dynamic IP’s of DHCP types to
users.But, if saving IP address as Domain Name, the problems caused by
changing IP addresses can be resolved because changed IP address can be
identified by DNS. This type of service is called DDNS, and the service can
be easily used by subscribing to DynDNS.org, etc. (
