NAPT
1.1 Introduction
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 DT800/DT700 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.
The router that the SV9100 resides behind still requires Port Forwarding
statements. However the router that the IP terminal/terminals reside behind may
not require any port forwarding.
Due to the fact that there are many manufacturers producing routers there may
still be times when port forwarding is required.
This feature is only effective when PRG 15-05-45 set to a "1" (ON).
In all software versions, SIP ALG’s (Application Level Gateway) or other SIP
Applications MUST be disabled in all routers. If a SIP ALG or a similar SIP
application is enabled, IP phone service WILL be interrupted.
