Description
After enabling the 3G network, you can initiate an H.323 or SIP
video conference using the terminal over the 3G network.
This specifies the mode for obtaining an IP address. The default
value is Dynamic. It is recommended that you use the default value.
l Dynamic: The terminal obtains an IP address dynamically and
automatically from the network.
l Static: The terminal uses an assigned IP address to connect to a
specific server.
l If IP address type is set to Dynamic, the IP address assigned
by the server is displayed in this text box only after a Point to
Point Protocol (PPP) connection is established successfully.
After being registered with the GK using the assigned IP address,
the terminal can call remote sites using the relevant numbers,
names, or IP addresses over the 3G network.
l If IP address type is set to Static, you can enter the IP address
manually.
When the terminal is connected to a 3G network in PPP dial-up
mode, the authentication mode can be set to PAP or CHAP to
prevent the access by unauthorized users. The default value is
CHAP. It is recommended that you use the default value.
l If you set the authentication mode to password authentication
protocol (PAP), the user name and the password are transmitted
over the network using plaintext. If the user name and the
password are captured during transmission, the network security
is at great risk. Thus, you can use the PAP mode when the
network security requirement is comparatively lower.
l If you set the authentication mode to the Challenge-Handshake
Authentication Protocol (CHAP), only the user name is
transmitted over the network. Thus, this authentication mode
provides a higher security level than the PAP mode. In CHAP
authentication mode, each inquiry message for authentication is
unpredictable and unique, thus preventing recurring network
attacks.
