Addressing

Regarding addressing of IP packets exchanged between IPT and the main system unit, the following restrictions are normally applied.

NAT (Network Address Translation)/NAPT (Network Address and Port Translation) devices NAT/NAPT devices must not be used for communication between the “IPT Anywhere” terminal and the interface card. The original IP header and UDP header must not be revised.

VPN Tunneling – By making the private IP address a capsule of the global IP address, the private IP address can be used to tunnel through the global IP network. Using tunneling makes communication between the “IPT Anywhere” telephone and the interface card transparent. Tunneling use requires that the carrier or the provider that the user is in contract with provides a tunneling device or that the user installs his/her own tunneling device separately.

Address system – It’s important to devise a control system to prevent the private IP addresses of the network for the “IPT Anywhere” telephone and the network to which the interface card installed in this terminal belongs from overlapping.
