You can also reboot a telephone by unplugging the power connector
from the telephone and then plugging it in again.
NBX system software (release R4.2 and higher) supports Network Address
Port Translation (NAPT, also called NAT overloading). NAPT allows you to
put an NBX 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
NBX Telephone directly to one of the Ethernet ports. Another option is
use the pcXset soft telephone application instead of an NBX Telephone.
This section summarizes the tasks you must complete to configure an
NBX Telephone for operation behind the NAPT device. Because the
configuration interface on each device varies, detailed procedures for
NAPT device configuration are beyond the scope of this document. For
information about configuring the NAPT device, see the documentation
for that device.
To add a broadband connected telephone behind a NAPT device:
1 Make sure the NBX system is set up for IP operations, either Standard IP
or IP On-the-Fly. If you are not using a VPN connection to establish access
from your home system to the NBX system network, the NBX system
must have a public IP address.
2 Use the NBX NetSet utility to enable Auto Discover Telephones (System
Configuration > System Settings > System-wide) and then connect the
NBX Telephone to the NBX system.
Auto discovering the telephone while it is connected locally to the NBX
network allows the system to configure the phone in the database and
assign an extension number. You could manually add the telephone to
the database instead of using the Auto Discover feature.
3 Move the telephone to its intended location. Connect it to power and
then use the telephone Local User Interface (LUI) utility to program these
settings:
and then click OK .
