NBX system software (release R4.2 and higher) supports Network Address
Port Translation (NAPT, also called NAT overloading). NAPT allows you to
put a 3Com Telephone behind a device that applies network address
translation at a remote location, such as a home office, and connect to
the NBX call processor through an Internet connection. One typical
configuration is to connect a cable/DSL modem to a small office/home
office router that includes a firewall and Ethernet ports. You connect the
3Com Telephone directly to one of the Ethernet ports. Another option is
use the pcXset soft telephone application instead of a 3Com Telephone.
For information about installing a remote telephone, see Chapter 3,
"Device Configuration," in the NBX Administrator's Guide.
