1.1.6 Other Network Settings

1.1.6.1 Global Address Detection

If the unit is connected to a network that uses a NAT router and a private IP address is assigned to each
terminal on the network, you must configure the STUN (Simple Traversal of UDP through NATs) function for
the unit so that the units can find the public IP and the new address will be registered to the SIP server. However,
if your phone system supports the SBC (Session Border Controller) function, it is not necessary to configure
these settings.
For details about the SBC function, consult your phone system dealer.
For details about specifying this setting through the Web user interface, see 4.3.8 Global Address
Detection.
Note
•For details about server information, consult your network administrator.

1.1.6.2 802.1x

802.1X provides port-based authentication, which involves communications between a Supplicant,
Authenticator, and Authentication server. The supplicant is often software on a client device, such as a laptop
or a VOIP phone, the authenticator is a wired Ethernet switch or wireless access point, and an authentication
server is generally a RADIUS database. The unit supports various EAP-methods including
EAP-MD5-Challenge, EAP-TLS, EAP-PEAP/GTC, EAP-PEAP/MSCHAPv2, EAP-TTLS/EAP-GTC, and
EAP-TTLS/EAP-MSCHAPv2.
