The phone only supports wired network connections. The phone USES an IP network
connection to provide services. Unlike traditional telephony based on circuit technology,
IP telephony exchanges packets and data over a network based on the IP address of the
telephony.

To enable the phone, the network configuration must be configured correctly; The default
network mode of the device is DHCP/IPv4.The client wants to modify the other modes
and needs to go to the device's web configuration interface.
Web interface: [network] >> [basic] select network mode

When using DHCP mode, phone will get the IP address from DHCP server (router).

⚫ Use DHCP DNS: It is enabled as default. “Enable” means phone will get DNS

address from DHCP server and “disable” means not.

⚫ Use DHCP time: It is disabled as default. “Enable” to manage the time of get

DNS address from DHCP server and “disable” means not.

When using PPPoE, phone will get the IP address from PPPoE server.

⚫ Username: PPPoE user name.
⚫ Password: PPPoE password.

When using Static IP mode, user must configure the IP address manually.

⚫ IP Address: Phone IP address.
⚫ Mask: sub mask of your LAN.

11.11 Network >> VPN

Virtual Private Network (VPN) is a technology to allow device to create a tunneling

connection to a server and becomes part of the server’s network. The network

transmission of the device may be routed through the VPN server.
For some users, especially enterprise users, a VPN connection might be required to be

31

established before activate a line registration. The device supports two VPN modes,
Layer 2 Transportation Protocol (L2TP) and OpenVPN.
The VPN connection must be configured and started (or stopped) from the device web
portal.
◼ L2TP

NOTICE! The device only supports non-encrypted basic authentication and
non-encrypted data tunneling. For users who need data encryption, please use
OpenVPN instead.

To establish a L2TP connection, users should log in to the device web portal, open
webpage [Network] >> [VPN]. In VPN Mode, check the “Enable VPN” option and select

“L2TP”, then fill in the L2TP server address, Authentication Username, and

Authentication Password in the L2TP section. Press “Apply” then the device will try to
connect to the L2TP server.
When the VPN connection established, the VPN IP Address should be displayed in the
VPN status. There may be some delay of the connection establishment. User may need
to refresh the page to update the status.
Once the VPN is configured, the device will try to connect with the VPN automatically
when the device boots up every time until user disable it. Sometimes, if the VPN
connection does not establish immediately, user may try to reboot the device and check
if VPN connection established after reboot.
◼ OpenVPN
To establish an OpenVPN connection, user should get the following authentication and
configuration files from the OpenVPN hosting provider and name them as the following,
OpenVPN Configuration file: client.ovpn

CA Root Certification: ca.crt
Client Certification: client.crt
Client Key: client.key

User then upload these files to the device in the web page [Network] >> [VPN], select

OpenVPN Files. Then user should check “Enable VPN” and select “OpenVPN” in VPN
Mode and click “Apply” to enable OpenVPN connection.

Same as L2TP connection, the connection will be established every time when system
rebooted until user disable it manually.

11.12 Network >> Advanced

◼ LLDP
Link Layer Discovery Protocol. LLDP is a vendor independent link layer protocol used by

32

network devices for advertising their identity, capabilities to neighbors on a LAN
segment.

Phone could use LLDP to find the VLAN switch or other VLAN devices and use LLDP
learn feature to apply the VLAN ID from VLAN switch to phone its self.

◼ CDP
Cisco Discovery Protocol. CDP is a not-for-profit charity that runs the global disclosure
system for investors, companies, cities, states and regions to manage their
environmental impacts. According to the CDP, Cisco devices could share the OS version,
IP address, hardware version and so on.

the Dial Peer rules.
In prefix matching, only part of the number is
entered followed by T. The mapping with then
take place whenever these digits are dialed.
Prefix mode supports a maximum of 30 digits.

Note: Two different special characters are used.

◼ x -- Matches any single digit that is dialed.
◼ [ ] -- Specifies a range of numbers to be matched. It may be a range, a list of ranges separated

by commas, or a list of digits.

Destination

Set Destination address. This is for IP direct.

Port

Set the Signal port, and the default is 5060 for
SIP.

Alias

Set the Alias. This is the text to be added,
replaced or deleted. It is an optional item.

Note: There are four types of aliases.
◼ all: xxx – xxx will replace the phone number.

43

◼ add: xxx – xxx will be dialed before any phone number.
◼ del –The characters will be deleted from the phone number.
◼ rep: xxx – xxx will be substituted for the specified characters.

Suffix

Characters to be added at the end of the phone
number. It is an optional item.

Length

Set the number of characters to be deleted. For
example, if this is set to 3, the phone will delete

optional item.

This feature allows the user to create rules to make dialing easier. There are several
different options for dial rules. The examples below will show how this can be used.

Example 1: All Substitution -- Assume that it is desired to place a direct IP call to IP
address 172.168.2.208. Using this feature, 123 can be substituted for 172.168.2.208.

Picture 21 - Dial rules table (1)

Example 2: Partial Substitution -- To dial a long distance call to Beijing requires dialing
area code 010 before the local phone number. Using this feature 1 can be substituted
for 010. For example, to call 62213123 would only require dialing 162213123 instead of

01062213123.

Src Address

Source address can be host address, network address, or
all addresses 0.0.0.0; It can also be a network address
similar to *.*.*.0, such as: 192.168.1.0.

Dst Address

The destination address can be either the specific IP
address or the full address 0.0.0.0; It can also be a
network address similar to *.*.*.0, such as: 192.168.1.0.

Src Mask

Is the source address mask. When configured as

255.255.255.255, it means that the host is specific. When
set as 255.255.255.0, it means that a network segment is
filtered.
