SV9100 Networking Manual
Programming Example
NAPT, or Network Address Port Translation, is a method by which a private address
or addresses and their TCP/UDP ports are translated into a single public address and
its TCP/UDP ports. In the case of IP phones with the SV9100 it allows their
connection to a public (internet) IP address which is then converted back to the
private (non-internet) IP address on the customers network. The translation is
available at the SV9100 end as well as at the remote IP Phone end of the connection
if required. The feature is NOT available for IP-CCIS and Netlink connections.
Note 1: The NAPT feature requires the following licenses to be loaded to the CPU: IP
Terminal (5111), Version 1000 (0411), VoIP Channel (5103), and System Port (0300).
