The default setting of DHCP Server inside VoIP Gateway is turn ON, So please set up
your PC TCP/IP network as “Get IP Automatically” from DHCP to get internal IP from
VoIP Gateway. By default, The VoIP Gateway will become the network gateway and
default IP is 192.168.22.1 and will assign your PC IP as 192.168.22.X.
Please go to “Control Panel”→”Network”. In the “Configure” page, choose the TCP/IP of
LAN card, and press “Properties” please choose “Obtain IP Address Automatically”
Launch your browser and open the Internal UI WAP page as 24H24H24Hhttp://192.168.22.1
The default User name is voip
The default Password is 1234
Please select the type of Internet connection you have
and set up the VoIP Gateway to use the Dynamic IP
Address, Static IP Address, PPPoE, PPTP or L2TP
connection.
If your ISP has not given you an IP address, select
Dynamic IP Address (default). If you have been given
a specific IP address, select Specify an IP Address.
To use Static-IP ADSL connection, please select “Static IP Address” and enter
WAN IP settings.
9
To use PPPoE ADSL connection, please select Yes in use “PPPoE” ADSL
service and enter the “username” and “password” in the PPPoE setup
section. Most of ADSL ISPs assign dynamic-IP settings to the VoIP Gateway
when using PPPoE. Please select Obtain IP Address Automatically(default
setting). You can leave the Primary and Secondary DNS IP settings in default.
The VoIP Gateway automatically obtains these settings from your ISP when
the PPPoE connection is successfully established.

3.3 Register Server
If this VoIP Gateway wants to use SIP Proxy or GateKeeper service to transfer
the VoIP call, you can input the server information here. The VoIP Gateway can
register to up to four servers simultaneously.
This page reveals the status of the server registration information.
Here is the server configuration page, please ask the information form your
ITSP.
Remark: For Notify remark for this rule. Please use UNDERLINE to
replace the SPACE due to HTTP protocol limitation.

3.4 VoIP Call Out
User key in the phone number through phone set dial pad, then VoIP Gateway
translate the phone number by the routing table setting here to destination IP & dial
out number then Call out via network protocol
Remark: For Notify remark for this rule. Please use UNDERLINE to
replace the SPACE due to HTTP protocol limitation.
Area Code: Define the Prefix number fit this rule, any phone number
prefix digits matched with the rule will call out by this rule define. Please
Notify there is a compare order rule on this routing table. That mean the
VoIP Gateway will check the rule list from top to bottom one by one, any rule
item matched with the prefix digits that user key in will go to call out directly
no regard to the rest rules below. For Example, if a rule item for area code
8862 is on Index 5, another rule item for area code 886 on Index 6 below
that will be ignored.
Min Digits: The length of the dialed number should not less than this
digits. For example, if the field is entered into ‘3’, the length of the dial
number should be 3 digits at least.
Max Digits: The length of the dialed number should not more than this
digits. For example, if the field is entered into ‘10’, the length of the dial
number should be 3 digits at most.
a. IP Address: Define the destination IP for call out number fit this rule, user
can input below format:
1
IP address, for example: 168.56.9.22
URL, route via URL. For example: www.inphonex.com .This VoIP
Gateway can setup to register to DDNS service (/System Setup
/Advanced/ Dynamic DNS/) to let user call out to another VoIP
Gateway with dynamic IP by URL.
rsn , route via server, it will get the destination IP by server setting
(/VoIP Setup/Register server/) in advance. For example: rs1 for
server 1. rs2 for server 2. rs for all the server available ( search
sequence: rs1 > rs2 > rs3 > rs4). rs3_2_1 will try rs3 first, then rs2,
then rs1.
IP address, for example: 168.56.9.22
All the setting above can be added by port number, for examples:
168.56.9.22:8495 will call to 8495 port.
Strip: the number of digits will be ignored by user input. For example, if
user key in the number is 886212345678 and the STRIPE field is setting to
4, the first 4 digits 8862 will be truncated and actually call out number will
be 12345678.
Prefix: The numbers will be added on the prefix of user key in number.
For examples, if user key in the number is 12345678 and the PREFIX field is
setting to 0028862, the actually call out number will be 002886212345678.
Another example, if user key in the number is 90, STRIP field is setting to 2,
and the PREFIX field is setting to 0,12345678, the actually call out number
will be 0,12345678 ( ,mean wait 1 second). This example is especially for
speed dial function.
To add new rule item on routing table, please assign the item number you want to
insert before, input AREA CODE and IP address then press ADD button to add it on
the list. Then modify the necessary information on the routing table list.
Please remember to press the modify button to take it effect. For store back to flash

digits matched with the rule will call out by this rule define. Please Notify
there is a compare order rule on this routing table. That mean the VoIP
Gateway will check the rule list from top to bottom one by one, any rule
item matched with the prefix digits that user press will go to call out directly
no regard to the rest rules below. For Example, if a rule item for area code
8862 is on Index 5, another rule item for area code 886 on Index 6 below
that will be ignored.
By setting the hln (hl1 for hot line one, hl2 for hot line two) on the area code
field and enable hot line function (/VoIP Setup/Line Configure/Line
Setting/), the VoIP Gateway can service the hot line direct call.
d. Min Digits: define the minimum digits wait for user press for number fit
this rule, if user press digits less the number defined here. It will keep

2. for h323 please add h323: before ip address , for example
h323:168.56.9.22
URL, route via URL. For example: sip.fwd.com .This VoIP Gateway can
setup to register to DDNS service (/System
Setup/Advanced/Dynamic DNS/) to let user call out to another VoIP
Gateway with dynamic IP by URL.
gkn : route via gatekeeper, it will get the destination IP by gatekeeper
setting (/VoIP Setup/Gatekeeper/) in advance. For example: gk1
3
for gatekeeper 1. gk2 for gatekeeper 2. gk for all the gatekeepers
available ( search sequence: gk1 > gk2 > gk3 > gk4). Gk3_2_1 will try
gk3 first, then gk2, then gk1.
All the setting above can be added by port number, for examples:
168.56.9.22:8495 will call to 8495 port.
srn, rsn: same as gkn , basically, it is used for SIP register
server.
PSTN: route this call via PSTN line interface. This is usually used
for the backup route for the rule setting on /Routing setup /VoIP
Call out/ with “v” prefix.
ipivr: Enter the Network parameter voice interactive setting
